12300204 divided by 837 
We want to divide 12300204 by 837.

Step 1:
The number 837 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 837

Moving on to step 2:
837 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 837

Advancing to step 3:
837 goes into 123 0 times with a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Fetch the next digit (0) from the dividend, attach it to 123 and continue: 1230 / 837

Step 4:
837 can be fit into 1230 1 times, resulting in a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 837 from 1230, we get 393.
Append the next digit (0) from the dividend to 393 and continue with: 3930 / 837

On to step 5:
3930 divided by 837 is 4 with a remainder of 582.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 3348 from 3930, we get 582.
Fetch the next digit (2) from the dividend, attach it to 582 and continue: 5822 / 837

Moving on to step 6:
The number 837 fits into 5822 6 times, leaving a remainder of 800.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
Deduct 5022 from 5822 and we're left with 800.
Fetch the next digit (0) from the dividend, attach it to 800 and continue: 8000 / 837

Going ahead to step 7:
The number 837 fits into 8000 9 times, leaving a remainder of 467.
Record the quotient 9 as the next digit in the result. 
Result so far: 1469.0
The remainder is 467 after subtracting 7533 from 8000.
Include the next digit (4) from the dividend after 467, then repeat: 4674 / 837

On to step 8:
The number 837 fits into 4674 5 times, leaving a remainder of 489.
Put 5 as the next digit of the answer. 
Result so far: 14695.0
Deduct 4185 from 4674 and we're left with 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Step 9:
837 goes into 4890 5 times with a remainder of 705.
The next digit of our result is 5. 
Result so far: 14695.5
Subtract 4185 from 4890 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Moving on to step 10:
7050 divided by 837 is 8 with a remainder of 354.
The next digit of our result is 8. 
Result so far: 14695.58
If we subtract 6696 from 7050, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 11:
When dividing 3540 by 837, we get 4 with a remainder of 192.
Put 4 as the next digit of the answer. 
Result so far: 14695.584
If we subtract 3348 from 3540, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 12:
837 can be fit into 1920 2 times, resulting in a remainder of 246.
The number 2 becomes the next digit in our result. 
Result so far: 14695.5842
Subtracting 1674 from 1920 leaves us 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 13:
837 can be fit into 2460 2 times, resulting in a remainder of 786.
Write down 2 as next digit of the result. 
Result so far: 14695.58422
Subtract 1674 from 2460 to get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

The quotient of the division is 14695.58422, and the remainder is 0.000786.
