839657 ÷ 86 
We want to figure out the number of times 839657 can be divided by 86.

On to step 1:
The number 86 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 86

On to step 2:
If we divide 83 by 86, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 86

Going ahead to step 3:
839 divided by 86 is 9 with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 774 from 839 leaves us with 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 86

On to step 4:
656 divided by 86 is 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 602 from 656, we get 54.
Bring next digit (5) of the dividend behind the 54 and repeat the process: 545 / 86

On to step 5:
When dividing 545 by 86, we get 6 with a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 976.0
Deduct 516 from 545 and we're left with 29.
Append the next digit (7) from the dividend to 29 and continue with: 297 / 86

Moving on to step 6:
If we divide 297 by 86, we get 3 and a remainder of 39.
Write down 3 as next digit of the result. 
Result so far: 9763.0
Deduct 258 from 297 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
86 can be fit into 390 4 times, resulting in a remainder of 46.
Record the quotient 4 as the next digit in the result. 
Result so far: 9763.4
If we take 344 away from 390, we end up 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 8:
460 divided by 86 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 9763.45
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 9763.453
Deduct 258 from 300 and we're left 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.

Going ahead to step 10:
420 divided by 86 is 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 9763.4534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
86 goes into 760 8 times with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 9763.45348
If we subtract 688 from 760, we 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.

Advancing to step 12:
If we divide 720 by 86, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 9763.453488
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 quotient of the division is 9763.453488, and the remainder is 3.2e-06.
