87928998 divided by 90 
Let's see how many times 90 fits into 87928998.

On to step 1:
8 divided by 90 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 90

On to step 2:
87 divided by 90 is 0 with a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Fetch the next digit (9) from the dividend, attach it to 87 and continue: 879 / 90

On to step 3:
879 divided by 90 is 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 69 after subtracting 810 from 879.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 90

Going ahead to step 4:
The number 90 fits into 692 7 times, leaving a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
The remainder is 62 after subtracting 630 from 692.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 90

Going ahead to step 5:
90 can be fit into 628 6 times, resulting in a remainder of 88.
Write down 6 as next digit of the result. 
Result so far: 976.0
The remainder is 88 after subtracting 540 from 628.
Append the next digit (9) from the dividend to 88 and continue with: 889 / 90

On to step 6:
The number 90 fits into 889 9 times, leaving a remainder of 79.
The next digit of our result is 9. 
Result so far: 9769.0
If we take 810 away from 889, we end up with 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 90

Advancing to step 7:
The number 90 fits into 799 8 times, leaving a remainder of 79.
The number 8 becomes the next digit in our result. 
Result so far: 97698.0
Subtracting 720 from 799 leaves us with 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 90

Advancing to step 8:
When dividing 798 by 90, we get 8 with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 976988.0
The remainder is 78 after subtracting 720 from 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
90 goes into 780 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 976988.8
Subtract 720 from 780 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
When dividing 600 by 90, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 976988.86
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
When dividing 600 by 90, we get 6 with a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 976988.866
If we take 540 away from 600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 976988.866 and a remainder of 0.006.
