Let's divide 30721280 by 838
We want to divide 30721280 by 838.

Advancing to step 1:
If we divide 3 by 838, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 838

Let's proceed to step 2:
The number 838 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 838

On to step 3:
When dividing 307 by 838, we get 0 with a remainder of 307.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 307 and we're left with 307.
Grab the next digit (2) from the dividend, add it to 307, then carry on: 3072 / 838

Moving on to step 4:
When dividing 3072 by 838, we get 3 with a remainder of 558.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 2514 from 3072 leaves us with 558.
Include the next digit (1) from the dividend after 558, then repeat: 5581 / 838

Advancing to step 5:
If we divide 5581 by 838, we get 6 and a remainder of 553.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 5028 from 5581, we get 553.
Grab the next digit (2) from the dividend, add it to 553, then carry on: 5532 / 838

Going ahead to step 6:
838 can be fit into 5532 6 times, resulting in a remainder of 504.
The next digit of our result is 6. 
Result so far: 366.0
If we take 5028 away from 5532, we end up with 504.
Append the next digit (8) from the dividend to 504 and continue with: 5048 / 838

Let's proceed to step 7:
838 can be fit into 5048 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 3666.0
Deduct 5028 from 5048 and we're left with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 838

Going ahead to step 8:
The number 838 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 36660.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 9:
838 can be fit into 2000 2 times, resulting in a remainder of 324.
The number 2 becomes the next digit in our result. 
Result so far: 36660.2
If we subtract 1676 from 2000, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 10:
The number 838 fits into 3240 3 times, leaving a remainder of 726.
The next digit of our result is 3. 
Result so far: 36660.23
If we take 2514 away from 3240, we end up with 726.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7260, and continue the process.

Advancing to step 11:
7260 divided by 838 is 8 with a remainder of 556.
Record the quotient 8 as the next digit in the result. 
Result so far: 36660.238
If we take 6704 away from 7260, we end up with 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Advancing to step 12:
When dividing 5560 by 838, we get 6 with a remainder of 532.
The number 6 becomes the next digit in our result. 
Result so far: 36660.2386
If we take 5028 away from 5560, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 13:
838 can be fit into 5320 6 times, resulting in a remainder of 292.
Write down 6 as next digit of the result. 
Result so far: 36660.23866
The remainder is 292 after subtracting 5028 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

After the division, we end up with 36660.23866 and a remainder of 0.000292.
