99160 divided by 90 
We want to figure out the number of times 99160 can be divided by 90.

Going ahead to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 90

Advancing to step 2:
When dividing 99 by 90, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 90 from 99 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 90

On to step 3:
When dividing 91 by 90, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 1 after subtracting 90 from 91.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 90

Step 4:
90 goes into 16 0 times with a remainder of 16.
The next digit of our result is 0. 
Result so far: 110.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 90

Going ahead to step 5:
90 can be fit into 160 1 times, resulting in a remainder of 70.
Record the quotient 1 as the next digit in the result. 
Result so far: 1101.0
The remainder is 70 after subtracting 90 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 6:
If we divide 700 by 90, we get 7 and a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 1101.7
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
If we divide 700 by 90, we get 7 and a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 1101.77
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The quotient of the division is 1101.77, and the remainder is 0.07.
