Let's divide 89510586 by 85
We want to divide 89510586 by 85.

On to step 1:
If we divide 8 by 85, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 85

Going ahead to step 2:
The number 85 fits into 89 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 85 from 89 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 85

Moving on to step 3:
85 can be fit into 45 0 times, resulting in a remainder of 45.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 85

Going ahead to step 4:
85 goes into 451 5 times with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtract 425 from 451 to get 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 85

Step 5:
The number 85 fits into 260 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 1053.0
The remainder is 5 after subtracting 255 from 260.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 85

Moving on to step 6:
85 goes into 55 0 times with a remainder of 55.
Record the quotient 0 as the next digit in the result. 
Result so far: 10530.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (8) from the dividend, attach it to 55 and continue: 558 / 85

Step 7:
When dividing 558 by 85, we get 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 105306.0
Subtract 510 from 558 to get 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 85

Moving on to step 8:
85 goes into 486 5 times with a remainder of 61.
The next digit of our result is 5. 
Result so far: 1053065.0
Subtracting 425 from 486 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
If we divide 610 by 85, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1053065.7
Subtract 595 from 610 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
85 goes into 150 1 times with a remainder of 65.
The next digit of our result is 1. 
Result so far: 1053065.71
The remainder is 65 after subtracting 85 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
If we divide 650 by 85, we get 7 and a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 1053065.717
If we subtract 595 from 650, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 12:
If we divide 550 by 85, we get 6 and a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 1053065.7176
Deduct 510 from 550 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
When dividing 400 by 85, we get 4 with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 1053065.71764
Deduct 340 from 400 and we're left 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.

Moving on to step 14:
85 can be fit into 600 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1053065.717647
The remainder is 5 after subtracting 595 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 15:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 1053065.717647
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 16:
85 goes into 500 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 1053065.71764705
Deduct 425 from 500 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 1053065.71764705 with a remainder of 7.5e-08.
