Let's divide 39948542 by 939
Our goal is to divide 39948542 by 939.

Advancing to step 1:
The number 939 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 939

Advancing to step 2:
The number 939 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 939

Let's proceed to step 3:
The number 939 fits into 399 0 times, leaving a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 399, we get 399.
Append the next digit (4) from the dividend to 399 and continue with: 3994 / 939

Going ahead to step 4:
If we divide 3994 by 939, we get 4 and a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 3756 from 3994, we get 238.
Bring next digit (8) of the dividend behind the 238 and repeat the process: 2388 / 939

Going ahead to step 5:
2388 divided by 939 is 2 with a remainder of 510.
Put 2 as the next digit of the answer. 
Result so far: 42.0
The remainder is 510 after subtracting 1878 from 2388.
Fetch the next digit (5) from the dividend, attach it to 510 and continue: 5105 / 939

Moving on to step 6:
If we divide 5105 by 939, we get 5 and a remainder of 410.
Put 5 as the next digit of the answer. 
Result so far: 425.0
Subtracting 4695 from 5105 leaves us with 410.
Include the next digit (4) from the dividend after 410, then repeat: 4104 / 939

Advancing to step 7:
4104 divided by 939 is 4 with a remainder of 348.
The next digit of our result is 4. 
Result so far: 4254.0
Deduct 3756 from 4104 and we're left with 348.
Grab the next digit (2) from the dividend, add it to 348, then carry on: 3482 / 939

Going ahead to step 8:
If we divide 3482 by 939, we get 3 and a remainder of 665.
Put 3 as the next digit of the answer. 
Result so far: 42543.0
If we subtract 2817 from 3482, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Step 9:
6650 divided by 939 is 7 with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 42543.7
Subtracting 6573 from 6650 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 10:
939 can be fit into 770 0 times, resulting in a remainder of 770.
Record the quotient 0 as the next digit in the result. 
Result so far: 42543.7
If we take 0 away from 770, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Step 11:
The number 939 fits into 7700 8 times, leaving a remainder of 188.
The next digit of our result is 8. 
Result so far: 42543.708
The remainder is 188 after subtracting 7512 from 7700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 12:
939 can be fit into 1880 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 42543.7082
The remainder is 2 after subtracting 1878 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
The number 939 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 42543.7082
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
939 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 42543.7082
Subtracting 0 from 200 leaves us 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.

The quotient of the division is 42543.7082, and the remainder is 2e-05.
