We're dividing 392992 by 86 
We're looking to find how many times 86 goes into 392992.

Advancing to step 1:
3 divided by 86 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 86

Going ahead to step 2:
86 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 86

Let's proceed to step 3:
392 divided by 86 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 48 after subtracting 344 from 392.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 86

Advancing to step 4:
86 goes into 489 5 times with a remainder of 59.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 430 from 489 leaves us with 59.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 86

Advancing to step 5:
If we divide 599 by 86, we get 6 and a remainder of 83.
The next digit of our result is 6. 
Result so far: 456.0
If we subtract 516 from 599, we get 83.
Take the next digit (2) from the dividend and append it to 83, then repeat: 832 / 86

Going ahead to step 6:
86 can be fit into 832 9 times, resulting in a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 4569.0
Deduct 774 from 832 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
When dividing 580 by 86, we get 6 with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 4569.6
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
When dividing 640 by 86, we get 7 with a remainder of 38.
The next digit of our result is 7. 
Result so far: 4569.67
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 4569.674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
If we divide 360 by 86, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4569.6744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4569.6744 and a remainder of 0.00016.
