We're dividing 31482201 by 855 
Our goal is to divide 31482201 by 855.

Moving on to step 1:
855 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 855

Going ahead to step 2:
When dividing 31 by 855, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 855

Going ahead to step 3:
855 can be fit into 314 0 times, resulting in a remainder of 314.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 314 leaves us with 314.
Include the next digit (8) from the dividend after 314, then repeat: 3148 / 855

On to step 4:
855 goes into 3148 3 times with a remainder of 583.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 2565 from 3148 and we're left with 583.
Take the next digit (2) from the dividend and append it to 583, then repeat: 5832 / 855

Advancing to step 5:
5832 divided by 855 is 6 with a remainder of 702.
Use 6 as the next digit of our solution. 
Result so far: 36.0
The remainder is 702 after subtracting 5130 from 5832.
Grab the next digit (2) from the dividend, add it to 702, then carry on: 7022 / 855

Advancing to step 6:
7022 divided by 855 is 8 with a remainder of 182.
Put 8 as the next digit of the answer. 
Result so far: 368.0
If we subtract 6840 from 7022, we get 182.
Bring next digit (0) of the dividend behind the 182 and repeat the process: 1820 / 855

Advancing to step 7:
855 can be fit into 1820 2 times, resulting in a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 3682.0
Deduct 1710 from 1820 and we're left with 110.
Include the next digit (1) from the dividend after 110, then repeat: 1101 / 855

On to step 8:
855 can be fit into 1101 1 times, resulting in a remainder of 246.
The number 1 becomes the next digit in our result. 
Result so far: 36821.0
Deduct 855 from 1101 and we're left with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 9:
855 can be fit into 2460 2 times, resulting in a remainder of 750.
Record the quotient 2 as the next digit in the result. 
Result so far: 36821.2
The remainder is 750 after subtracting 1710 from 2460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Step 10:
7500 divided by 855 is 8 with a remainder of 660.
Use 8 as the next digit of our solution. 
Result so far: 36821.28
Subtracting 6840 from 7500 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

On to step 11:
855 can be fit into 6600 7 times, resulting in a remainder of 615.
The next digit of our result is 7. 
Result so far: 36821.287
The remainder is 615 after subtracting 5985 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

On to step 12:
855 can be fit into 6150 7 times, resulting in a remainder of 165.
The number 7 becomes the next digit in our result. 
Result so far: 36821.2877
Subtracting 5985 from 6150 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final result is 36821.2877 with a remainder of 0.00165.
