We look at the division of 685561 by 86 
We want to divide 685561 by 86.

Let's proceed to step 1:
86 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 86

Advancing to step 2:
If we divide 68 by 86, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (5) from the dividend, attach it to 68 and continue: 685 / 86

Advancing to step 3:
When dividing 685 by 86, we get 7 with a remainder of 83.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 83 after subtracting 602 from 685.
Bring next digit (5) of the dividend behind the 83 and repeat the process: 835 / 86

Moving on to step 4:
When dividing 835 by 86, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we take 774 away from 835, we end up with 61.
Take the next digit (6) from the dividend and append it to 61, then repeat: 616 / 86

Moving on to step 5:
616 divided by 86 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 797.0
Subtracting 602 from 616 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 86

Going ahead to step 6:
The number 86 fits into 141 1 times, leaving a remainder of 55.
The next digit of our result is 1. 
Result so far: 7971.0
The remainder is 55 after subtracting 86 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
550 divided by 86 is 6 with a remainder of 34.
The next digit of our result is 6. 
Result so far: 7971.6
Subtract 516 from 550 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
86 goes into 340 3 times with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 7971.63
If we take 258 away from 340, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 9:
86 goes into 820 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 7971.639
Deduct 774 from 820 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 7971.6395
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
300 divided by 86 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 7971.63953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 7971.639534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
86 goes into 760 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 7971.6395348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 14:
When dividing 720 by 86, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 7971.63953488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 7971.63953488 with a remainder of 3.2e-08.
