686031 divided by 86 
We want to figure out the number of times 686031 can be divided by 86.

Step 1:
86 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 86

Going ahead to step 2:
When dividing 68 by 86, we get 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 86

Moving on to step 3:
86 can be fit into 686 7 times, resulting in a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 84 after subtracting 602 from 686.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 86

Let's proceed to step 4:
When dividing 840 by 86, we get 9 with a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 79.0
Subtract 774 from 840 to get 66.
Include the next digit (3) from the dividend after 66, then repeat: 663 / 86

On to step 5:
86 goes into 663 7 times with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 797.0
Subtracting 602 from 663 leaves us with 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 86

Going ahead to step 6:
The number 86 fits into 611 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 7977.0
If we take 602 away from 611, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
86 can be fit into 90 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 7977.1
Deduct 86 from 90 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 86 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7977.1
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
The number 86 fits into 400 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 7977.104
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
The number 86 fits into 560 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 7977.1046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 11:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7977.10465
Subtract 430 from 440 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.

Going ahead to step 12:
The number 86 fits into 100 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 7977.104651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
86 goes into 140 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 7977.1046511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 7977.1046511, and the remainder is 5.4e-07.
