Let's divide 815129 by 85
Let's see how many times 85 fits into 815129.

Step 1:
The number 85 fits into 8 0 times, leaving 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 85

Step 2:
When dividing 81 by 85, we get 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (5) of the dividend behind the 81 and repeat the process: 815 / 85

Going ahead to step 3:
815 divided by 85 is 9 with a remainder of 50.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 765 from 815 leaves us with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 85

On to step 4:
If we divide 501 by 85, we get 5 and a remainder of 76.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtracting 425 from 501 leaves us with 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 85

On to step 5:
85 can be fit into 762 8 times, resulting in a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 958.0
If we subtract 680 from 762, we get 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 85

Moving on to step 6:
85 goes into 829 9 times with a remainder of 64.
The next digit of our result is 9. 
Result so far: 9589.0
Subtracting 765 from 829 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
If we divide 640 by 85, we get 7 and a remainder of 45.
The next digit of our result is 7. 
Result so far: 9589.7
Deduct 595 from 640 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
85 goes into 450 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 9589.75
Deduct 425 from 450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
85 goes into 250 2 times with a remainder of 80.
Put 2 as the next digit of the answer. 
Result so far: 9589.752
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.

Advancing to step 10:
85 goes into 800 9 times with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 9589.7529
If we take 765 away from 800, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 11:
350 divided by 85 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 9589.75294
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.

Let's proceed to step 12:
The number 85 fits into 100 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 9589.752941
Subtract 85 from 100 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.

On to step 13:
If we divide 150 by 85, we get 1 and a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 9589.7529411
Subtract 85 from 150 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 9589.7529411 with a remaining 6.5e-07.
