We're dividing 987717 by 90 
Our goal is to divide 987717 by 90.

Advancing to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 90

Going ahead to step 2:
The number 90 fits into 98 1 times, leaving a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 90 from 98 to get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 90

On to step 3:
If we divide 87 by 90, we get 0 and a remainder of 87.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 90

Moving on to step 4:
877 divided by 90 is 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
The remainder is 67 after subtracting 810 from 877.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 90

Advancing to step 5:
The number 90 fits into 671 7 times, leaving a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 1097.0
If we take 630 away from 671, we end up with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 90

Step 6:
When dividing 417 by 90, we get 4 with a remainder of 57.
The number 4 becomes the next digit in our result. 
Result so far: 10974.0
Subtracting 360 from 417 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
90 goes into 570 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 10974.6
The remainder is 30 after subtracting 540 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 10974.63
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 10974.633
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 10974.633, with a leftover of 0.003.
