Let's divide 853121 by 85
We want to divide 853121 by 85.

On to step 1:
85 can be fit into 8 0 times, resulting in 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.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 85

Moving on to step 2:
If we divide 85 by 85, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 85 away from 85, we end up with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 85

Step 3:
The number 85 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 85

Let's proceed to step 4:
If we divide 31 by 85, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtracting 0 from 31 leaves us with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 85

Let's proceed to step 5:
When dividing 312 by 85, we get 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 1003.0
Deduct 255 from 312 and we're left with 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 85

Let's proceed to step 6:
When dividing 571 by 85, we get 6 with a remainder of 61.
Put 6 as the next digit of the answer. 
Result so far: 10036.0
If we take 510 away from 571, we end up 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.

Moving on to step 7:
85 goes into 610 7 times with a remainder of 15.
The next digit of our result is 7. 
Result so far: 10036.7
If we subtract 595 from 610, 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.

Step 8:
85 goes into 150 1 times with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 10036.71
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.

Let's proceed to step 9:
If we divide 650 by 85, we get 7 and a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 10036.717
If we take 595 away from 650, we end up with 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 10:
The number 85 fits into 550 6 times, leaving a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 10036.7176
The remainder is 40 after subtracting 510 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
85 goes into 400 4 times with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 10036.71764
If we subtract 340 from 400, we 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.

Advancing to step 12:
When dividing 600 by 85, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 10036.717647
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.

Moving on to step 13:
85 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 10036.717647
If we take 0 away from 50, we end up 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.

Moving on to step 14:
If we divide 500 by 85, we get 5 and a remainder of 75.
The next digit of our result is 5. 
Result so far: 10036.71764705
If we take 425 away from 500, we end up 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 quotient of the division is 10036.71764705, and the remainder is 7.5e-08.
