Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Harrison Elementary School is overcrowded with 1590 students, so 40% of the students are going to move to a new school. There are 3 grade levels, and each grade level needs one 20-person advanced class and the rest of the students divided evenly into 6 additional classes. How many students will there be in each normal class at the new school?

### Response:
 Kwanza tafuta idadi ya wanafunzi wanaohamia shule mpya: wanafunzi 1590 * .4 = <<1590*.4=636>>636 wanafunzi
Kisha ugawanye idadi hiyo kwa 3 ili kupata idadi ya wanafunzi katika kila ngazi ya darasa: wanafunzi 636 / 3 ngazi = <<636/3=212>>212 wanafunzi/ngazi
Kisha toa wanafunzi 20 katika darasa la juu: wanafunzi 212 - 20 wanafunzi = <<212-20=192>>192 wanafunzi
Kisha ugawanye idadi hiyo kwa 6 ili kupata idadi ya wanafunzi katika kila darasa lingine: wanafunzi 192 / 6 madarasa = <<192/6=32>>32 wanafunzi/darasa
