99089681 ÷ 85 
Our goal is to divide 99089681 by 85.

On to step 1:
When dividing 9 by 85, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 85

Moving on to step 2:
When dividing 99 by 85, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 85 from 99 leaves us with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 85

Step 3:
140 divided by 85 is 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 85 from 140, we get 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 85

On to step 4:
558 divided by 85 is 6 with a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Deduct 510 from 558 and we're left with 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 85

Step 5:
85 goes into 489 5 times with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 1165.0
Deduct 425 from 489 and we're left with 64.
Bring next digit (6) of the dividend behind the 64 and repeat the process: 646 / 85

Advancing to step 6:
85 goes into 646 7 times with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 11657.0
The remainder is 51 after subtracting 595 from 646.
Grab the next digit (8) from the dividend, add it to 51, then carry on: 518 / 85

Moving on to step 7:
85 goes into 518 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 116576.0
The remainder is 8 after subtracting 510 from 518.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 85

Moving on to step 8:
81 divided by 85 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 1165760.0
Deduct 0 from 81 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 9:
85 can be fit into 810 9 times, resulting in a remainder of 45.
Put 9 as the next digit of the answer. 
Result so far: 1165760.9
If we subtract 765 from 810, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
The number 85 fits into 450 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1165760.95
If we subtract 425 from 450, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 11:
The number 85 fits into 250 2 times, leaving a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 1165760.952
If we take 170 away from 250, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
When dividing 800 by 85, we get 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 1165760.9529
The remainder is 35 after subtracting 765 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
When dividing 350 by 85, we get 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 1165760.95294
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1165760.952941
If we subtract 85 from 100, we 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.

On to step 15:
85 goes into 150 1 times with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 1165760.9529411
Deduct 85 from 150 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 1165760.9529411 and a remainder of 6.5e-07.
