Let's divide 869543 by 85
Our goal is to divide 869543 by 85.

Advancing to step 1:
85 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 85

Going ahead to step 2:
86 divided by 85 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 85 from 86 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 85

Going ahead to step 3:
If we divide 19 by 85, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 19, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 85

Going ahead to step 4:
195 divided by 85 is 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 25 after subtracting 170 from 195.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 85

Going ahead to step 5:
254 divided by 85 is 2 with a remainder of 84.
The next digit of our result is 2. 
Result so far: 1022.0
The remainder is 84 after subtracting 170 from 254.
Grab the next digit (3) from the dividend, add it to 84, then carry on: 843 / 85

Moving on to step 6:
85 can be fit into 843 9 times, resulting in a remainder of 78.
The next digit of our result is 9. 
Result so far: 10229.0
If we take 765 away from 843, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 7:
When dividing 780 by 85, we get 9 with a remainder of 15.
The next digit of our result is 9. 
Result so far: 10229.9
Subtracting 765 from 780 leaves us with 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 8:
85 goes into 150 1 times with a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 10229.91
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.

Going ahead to step 9:
The number 85 fits into 650 7 times, leaving a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 10229.917
The remainder is 55 after subtracting 595 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
550 divided by 85 is 6 with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 10229.9176
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.

Going ahead to step 11:
If we divide 400 by 85, we get 4 and a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 10229.91764
The remainder is 60 after subtracting 340 from 400.
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 12:
600 divided by 85 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 10229.917647
Subtract 595 from 600 to get 5.
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 13:
50 divided by 85 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10229.917647
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.

Moving on to step 14:
When dividing 500 by 85, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 10229.91764705
Subtracting 425 from 500 leaves us 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 10229.91764705 with a remainder of 7.5e-08.
