We're dividing 20115321 by 939 
Let's see how many times 939 fits into 20115321.

Let's proceed to step 1:
939 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 939

Let's proceed to step 2:
20 divided by 939 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 939

On to step 3:
If we divide 201 by 939, we get 0 and a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 201, we end up with 201.
Take the next digit (1) from the dividend and append it to 201, then repeat: 2011 / 939

Step 4:
If we divide 2011 by 939, we get 2 and a remainder of 133.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1878 from 2011 and we're left with 133.
Take the next digit (5) from the dividend and append it to 133, then repeat: 1335 / 939

Let's proceed to step 5:
939 goes into 1335 1 times with a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 396 after subtracting 939 from 1335.
Append the next digit (3) from the dividend to 396 and continue with: 3963 / 939

Step 6:
If we divide 3963 by 939, we get 4 and a remainder of 207.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
If we take 3756 away from 3963, we end up with 207.
Fetch the next digit (2) from the dividend, attach it to 207 and continue: 2072 / 939

Step 7:
When dividing 2072 by 939, we get 2 with a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 2142.0
If we subtract 1878 from 2072, we get 194.
Bring next digit (1) of the dividend behind the 194 and repeat the process: 1941 / 939

Let's proceed to step 8:
1941 divided by 939 is 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 21422.0
If we subtract 1878 from 1941, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 9:
If we divide 630 by 939, we get 0 and a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 21422.0
If we subtract 0 from 630, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 10:
The number 939 fits into 6300 6 times, leaving a remainder of 666.
Use 6 as the next digit of our solution. 
Result so far: 21422.06
Subtract 5634 from 6300 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Step 11:
The number 939 fits into 6660 7 times, leaving a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 21422.067
If we take 6573 away from 6660, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 12:
939 can be fit into 870 0 times, resulting in a remainder of 870.
Use 0 as the next digit of our solution. 
Result so far: 21422.067
Subtract 0 from 870 to get 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

Step 13:
8700 divided by 939 is 9 with a remainder of 249.
The number 9 becomes the next digit in our result. 
Result so far: 21422.06709
Subtracting 8451 from 8700 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

On to step 14:
When dividing 2490 by 939, we get 2 with a remainder of 612.
Write down 2 as next digit of the result. 
Result so far: 21422.067092
If we take 1878 away from 2490, we end up with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

On to step 15:
939 can be fit into 6120 6 times, resulting in a remainder of 486.
The next digit of our result is 6. 
Result so far: 21422.0670926
If we take 5634 away from 6120, we end up with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Step 16:
If we divide 4860 by 939, we get 5 and a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 21422.06709265
If we subtract 4695 from 4860, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

After the division, we end up with 21422.06709265 and a remainder of 1.65e-07.
