We're dividing 39359938 by 621 
We want to divide 39359938 by 621.

Advancing to step 1:
If we divide 3 by 621, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 621

Going ahead to step 2:
621 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 621

Advancing to step 3:
621 goes into 393 0 times with a remainder of 393.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 393, we get 393.
Include the next digit (5) from the dividend after 393, then repeat: 3935 / 621

Moving on to step 4:
3935 divided by 621 is 6 with a remainder of 209.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 209 after subtracting 3726 from 3935.
Append the next digit (9) from the dividend to 209 and continue with: 2099 / 621

On to step 5:
The number 621 fits into 2099 3 times, leaving a remainder of 236.
The next digit of our result is 3. 
Result so far: 63.0
If we take 1863 away from 2099, we end up with 236.
Take the next digit (9) from the dividend and append it to 236, then repeat: 2369 / 621

Let's proceed to step 6:
If we divide 2369 by 621, we get 3 and a remainder of 506.
The number 3 becomes the next digit in our result. 
Result so far: 633.0
If we take 1863 away from 2369, we end up with 506.
Bring next digit (3) of the dividend behind the 506 and repeat the process: 5063 / 621

On to step 7:
When dividing 5063 by 621, we get 8 with a remainder of 95.
Put 8 as the next digit of the answer. 
Result so far: 6338.0
If we take 4968 away from 5063, we end up with 95.
Bring next digit (8) of the dividend behind the 95 and repeat the process: 958 / 621

Going ahead to step 8:
621 can be fit into 958 1 times, resulting in a remainder of 337.
The number 1 becomes the next digit in our result. 
Result so far: 63381.0
If we take 621 away from 958, we end up with 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Going ahead to step 9:
621 goes into 3370 5 times with a remainder of 265.
The next digit of our result is 5. 
Result so far: 63381.5
Subtracting 3105 from 3370 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 10:
2650 divided by 621 is 4 with a remainder of 166.
Write down 4 as next digit of the result. 
Result so far: 63381.54
The remainder is 166 after subtracting 2484 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 11:
The number 621 fits into 1660 2 times, leaving a remainder of 418.
Write down 2 as next digit of the result. 
Result so far: 63381.542
Deduct 1242 from 1660 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Let's proceed to step 12:
The number 621 fits into 4180 6 times, leaving a remainder of 454.
Write down 6 as next digit of the result. 
Result so far: 63381.5426
The remainder is 454 after subtracting 3726 from 4180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 13:
The number 621 fits into 4540 7 times, leaving a remainder of 193.
Record the quotient 7 as the next digit in the result. 
Result so far: 63381.54267
The remainder is 193 after subtracting 4347 from 4540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 14:
621 goes into 1930 3 times with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 63381.542673
If we subtract 1863 from 1930, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 15:
When dividing 670 by 621, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 63381.5426731
Subtracting 621 from 670 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 16:
621 can be fit into 490 0 times, resulting in a remainder of 490.
Record the quotient 0 as the next digit in the result. 
Result so far: 63381.5426731
The remainder is 490 after subtracting 0 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

In conclusion, the division gives 63381.5426731 with a balance of 4.9e-07.
