Let's divide 83838824 by 621
Our goal is to divide 83838824 by 621.

On to step 1:
8 divided by 621 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 621

Step 2:
621 goes into 83 0 times with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 621

On to step 3:
838 divided by 621 is 1 with a remainder of 217.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 621 from 838 leaves us with 217.
Append the next digit (3) from the dividend to 217 and continue with: 2173 / 621

On to step 4:
621 can be fit into 2173 3 times, resulting in a remainder of 310.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 1863 away from 2173, we end up with 310.
Bring next digit (8) of the dividend behind the 310 and repeat the process: 3108 / 621

Step 5:
When dividing 3108 by 621, we get 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 135.0
Subtract 3105 from 3108 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 621

On to step 6:
621 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 1350.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 621

Moving on to step 7:
The number 621 fits into 382 0 times, leaving a remainder of 382.
Use 0 as the next digit of our solution. 
Result so far: 13500.0
If we take 0 away from 382, we end up with 382.
Grab the next digit (4) from the dividend, add it to 382, then carry on: 3824 / 621

Step 8:
The number 621 fits into 3824 6 times, leaving a remainder of 98.
The next digit of our result is 6. 
Result so far: 135006.0
The remainder is 98 after subtracting 3726 from 3824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 9:
The number 621 fits into 980 1 times, leaving a remainder of 359.
The number 1 becomes the next digit in our result. 
Result so far: 135006.1
The remainder is 359 after subtracting 621 from 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Step 10:
3590 divided by 621 is 5 with a remainder of 485.
The number 5 becomes the next digit in our result. 
Result so far: 135006.15
Subtracting 3105 from 3590 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Going ahead to step 11:
621 goes into 4850 7 times with a remainder of 503.
The number 7 becomes the next digit in our result. 
Result so far: 135006.157
If we subtract 4347 from 4850, we get 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Let's proceed to step 12:
621 can be fit into 5030 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 135006.1578
Deduct 4968 from 5030 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
If we divide 620 by 621, we get 0 and a remainder of 620.
Write down 0 as next digit of the result. 
Result so far: 135006.1578
Subtracting 0 from 620 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Moving on to step 14:
If we divide 6200 by 621, we get 9 and a remainder of 611.
The next digit of our result is 9. 
Result so far: 135006.157809
Subtract 5589 from 6200 to get 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 15:
If we divide 6110 by 621, we get 9 and a remainder of 521.
Use 9 as the next digit of our solution. 
Result so far: 135006.1578099
Subtracting 5589 from 6110 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

After the division, we end up with 135006.1578099 and a remainder of 5.21e-06.
