We look at the division of 39903662 by 938 
We want to divide 39903662 by 938.

Advancing to step 1:
3 divided by 938 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 938

Advancing to step 2:
938 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 938

Going ahead to step 3:
938 goes into 399 0 times with a remainder of 399.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 399 and we're left with 399.
Append the next digit (0) from the dividend to 399 and continue with: 3990 / 938

Going ahead to step 4:
938 can be fit into 3990 4 times, resulting in a remainder of 238.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 3752 away from 3990, we end up with 238.
Take the next digit (3) from the dividend and append it to 238, then repeat: 2383 / 938

On to step 5:
When dividing 2383 by 938, we get 2 with a remainder of 507.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 507 after subtracting 1876 from 2383.
Append the next digit (6) from the dividend to 507 and continue with: 5076 / 938

Let's proceed to step 6:
5076 divided by 938 is 5 with a remainder of 386.
Put 5 as the next digit of the answer. 
Result so far: 425.0
The remainder is 386 after subtracting 4690 from 5076.
Bring next digit (6) of the dividend behind the 386 and repeat the process: 3866 / 938

Let's proceed to step 7:
When dividing 3866 by 938, we get 4 with a remainder of 114.
Record the quotient 4 as the next digit in the result. 
Result so far: 4254.0
The remainder is 114 after subtracting 3752 from 3866.
Grab the next digit (2) from the dividend, add it to 114, then carry on: 1142 / 938

On to step 8:
1142 divided by 938 is 1 with a remainder of 204.
Use 1 as the next digit of our solution. 
Result so far: 42541.0
Subtracting 938 from 1142 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 9:
The number 938 fits into 2040 2 times, leaving a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 42541.2
Subtracting 1876 from 2040 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 10:
1640 divided by 938 is 1 with a remainder of 702.
Record the quotient 1 as the next digit in the result. 
Result so far: 42541.21
Subtract 938 from 1640 to get 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Step 11:
If we divide 7020 by 938, we get 7 and a remainder of 454.
The next digit of our result is 7. 
Result so far: 42541.217
Subtracting 6566 from 7020 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 12:
938 goes into 4540 4 times with a remainder of 788.
The number 4 becomes the next digit in our result. 
Result so far: 42541.2174
Deduct 3752 from 4540 and we're left with 788.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7880, and continue the process.

Going ahead to step 13:
When dividing 7880 by 938, we get 8 with a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 42541.21748
If we subtract 7504 from 7880, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 14:
When dividing 3760 by 938, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 42541.217484
Deduct 3752 from 3760 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 15:
80 divided by 938 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 42541.217484
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
When dividing 800 by 938, we get 0 with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 42541.217484
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 42541.217484 with a remaining 8e-07.
