We're dividing 3962412 by 855 
Our goal is to divide 3962412 by 855.

On to step 1:
The number 855 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 855

Going ahead to step 2:
When dividing 39 by 855, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 855

On to step 3:
When dividing 396 by 855, we get 0 with a remainder of 396.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 396 after subtracting 0 from 396.
Take the next digit (2) from the dividend and append it to 396, then repeat: 3962 / 855

On to step 4:
When dividing 3962 by 855, we get 4 with a remainder of 542.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 542 after subtracting 3420 from 3962.
Take the next digit (4) from the dividend and append it to 542, then repeat: 5424 / 855

Advancing to step 5:
If we divide 5424 by 855, we get 6 and a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 46.0
The remainder is 294 after subtracting 5130 from 5424.
Append the next digit (1) from the dividend to 294 and continue with: 2941 / 855

On to step 6:
If we divide 2941 by 855, we get 3 and a remainder of 376.
Put 3 as the next digit of the answer. 
Result so far: 463.0
If we subtract 2565 from 2941, we get 376.
Bring next digit (2) of the dividend behind the 376 and repeat the process: 3762 / 855

Let's proceed to step 7:
When dividing 3762 by 855, we get 4 with a remainder of 342.
Use 4 as the next digit of our solution. 
Result so far: 4634.0
Deduct 3420 from 3762 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 8:
The number 855 fits into 3420 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4634.4
If we take 3420 away from 3420, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
855 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4634.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 855, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4634.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4634.4 and a remainder of 0.0.
