We're dividing 18039831 by 921 
We want to figure out the number of times 18039831 can be divided by 921.

Moving on to step 1:
The number 921 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 921

Going ahead to step 2:
The number 921 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 921

On to step 3:
921 goes into 180 0 times with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 180 after subtracting 0 from 180.
Include the next digit (3) from the dividend after 180, then repeat: 1803 / 921

Step 4:
The number 921 fits into 1803 1 times, leaving a remainder of 882.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 921 from 1803 leaves us with 882.
Grab the next digit (9) from the dividend, add it to 882, then carry on: 8829 / 921

Advancing to step 5:
When dividing 8829 by 921, we get 9 with a remainder of 540.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 8289 from 8829 and we're left with 540.
Fetch the next digit (8) from the dividend, attach it to 540 and continue: 5408 / 921

Advancing to step 6:
921 can be fit into 5408 5 times, resulting in a remainder of 803.
Write down 5 as next digit of the result. 
Result so far: 195.0
Deduct 4605 from 5408 and we're left with 803.
Take the next digit (3) from the dividend and append it to 803, then repeat: 8033 / 921

Advancing to step 7:
If we divide 8033 by 921, we get 8 and a remainder of 665.
The next digit of our result is 8. 
Result so far: 1958.0
If we take 7368 away from 8033, we end up with 665.
Bring next digit (1) of the dividend behind the 665 and repeat the process: 6651 / 921

Let's proceed to step 8:
921 goes into 6651 7 times with a remainder of 204.
Record the quotient 7 as the next digit in the result. 
Result so far: 19587.0
The remainder is 204 after subtracting 6447 from 6651.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 9:
When dividing 2040 by 921, we get 2 with a remainder of 198.
The number 2 becomes the next digit in our result. 
Result so far: 19587.2
If we subtract 1842 from 2040, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 10:
921 goes into 1980 2 times with a remainder of 138.
The number 2 becomes the next digit in our result. 
Result so far: 19587.22
Deduct 1842 from 1980 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Our division results in 19587.22 with a remaining 0.138.
