We look at the division of 39246972 by 855 
We want to divide 39246972 by 855.

Moving on to step 1:
When dividing 3 by 855, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 855

On to step 2:
The number 855 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 855

Step 3:
855 can be fit into 392 0 times, resulting in a remainder of 392.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 392, we get 392.
Grab the next digit (4) from the dividend, add it to 392, then carry on: 3924 / 855

Let's proceed to step 4:
The number 855 fits into 3924 4 times, leaving a remainder of 504.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3420 from 3924 and we're left with 504.
Grab the next digit (6) from the dividend, add it to 504, then carry on: 5046 / 855

Step 5:
855 can be fit into 5046 5 times, resulting in a remainder of 771.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 4275 from 5046 leaves us with 771.
Grab the next digit (9) from the dividend, add it to 771, then carry on: 7719 / 855

Advancing to step 6:
When dividing 7719 by 855, we get 9 with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
Subtracting 7695 from 7719 leaves us with 24.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 855

Let's proceed to step 7:
If we divide 247 by 855, we get 0 and a remainder of 247.
Use 0 as the next digit of our solution. 
Result so far: 4590.0
The remainder is 247 after subtracting 0 from 247.
Include the next digit (2) from the dividend after 247, then repeat: 2472 / 855

Advancing to step 8:
855 can be fit into 2472 2 times, resulting in a remainder of 762.
Put 2 as the next digit of the answer. 
Result so far: 45902.0
Subtracting 1710 from 2472 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

Advancing to step 9:
If we divide 7620 by 855, we get 8 and a remainder of 780.
The next digit of our result is 8. 
Result so far: 45902.8
Subtracting 6840 from 7620 leaves us with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 10:
The number 855 fits into 7800 9 times, leaving a remainder of 105.
Write down 9 as next digit of the result. 
Result so far: 45902.89
The remainder is 105 after subtracting 7695 from 7800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Moving on to step 11:
When dividing 1050 by 855, we get 1 with a remainder of 195.
Use 1 as the next digit of our solution. 
Result so far: 45902.891
Subtract 855 from 1050 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 12:
The number 855 fits into 1950 2 times, leaving a remainder of 240.
The next digit of our result is 2. 
Result so far: 45902.8912
If we take 1710 away from 1950, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 13:
855 can be fit into 2400 2 times, resulting in a remainder of 690.
Write down 2 as next digit of the result. 
Result so far: 45902.89122
Subtracting 1710 from 2400 leaves us with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

The quotient of the division is 45902.89122, and the remainder is 0.00069.
