Let's divide 88516802 by 90
We want to divide 88516802 by 90.

Advancing to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 90

Let's proceed to step 2:
88 divided by 90 is 0 with a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Fetch the next digit (5) from the dividend, attach it to 88 and continue: 885 / 90

Step 3:
The number 90 fits into 885 9 times, leaving a remainder of 75.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 810 from 885 leaves us with 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 90

Going ahead to step 4:
90 goes into 751 8 times with a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we take 720 away from 751, we end up with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 90

Step 5:
90 can be fit into 316 3 times, resulting in a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 983.0
The remainder is 46 after subtracting 270 from 316.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 90

On to step 6:
90 goes into 468 5 times with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 9835.0
The remainder is 18 after subtracting 450 from 468.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 90

Step 7:
When dividing 180 by 90, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 98352.0
Deduct 180 from 180 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 90

Step 8:
If we divide 2 by 90, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 983520.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 90 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 983520.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
200 divided by 90 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 983520.02
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
90 goes into 200 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 983520.022
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 983520.022, with a leftover of 0.002.
