The number 921 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 921

Advancing to step 2:
78 divided by 921 is 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 921

Moving on to step 3:
921 goes into 787 0 times with a remainder of 787.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 787, we end up with 787.
Fetch the next digit (8) from the dividend, attach it to 787 and continue: 7878 / 921

Step 4:
If we divide 7878 by 921, we get 8 and a remainder of 510.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 7368 from 7878 and we're left with 510.
Append the next digit (5) from the dividend to 510 and continue with: 5105 / 921

Moving on to step 5:
The number 921 fits into 5105 5 times, leaving a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 4605 from 5105 leaves us with 500.
Append the next digit (3) from the dividend to 500 and continue with: 5003 / 921

Let's proceed to step 6:
5003 divided by 921 is 5 with a remainder of 398.
Put 5 as the next digit of the answer. 
Result so far: 855.0
The remainder is 398 after subtracting 4605 from 5003.
Append the next digit (6) from the dividend to 398 and continue with: 3986 / 921

Step 7:
921 can be fit into 3986 4 times, resulting in a remainder of 302.
The number 4 becomes the next digit in our result. 
Result so far: 8554.0
Subtract 3684 from 3986 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 8:
If we divide 3020 by 921, we get 3 and a remainder of 257.
Write down 3 as next digit of the result. 
Result so far: 8554.3
Subtracting 2763 from 3020 leaves us with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 9:
921 can be fit into 2570 2 times, resulting in a remainder of 728.
Write down 2 as next digit of the result. 
Result so far: 8554.32
The remainder is 728 after subtracting 1842 from 2570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7280, and continue the process.

On to step 10:
921 goes into 7280 7 times with a remainder of 833.
Record the quotient 7 as the next digit in the result. 
Result so far: 8554.327
Deduct 6447 from 7280 and we're left with 833.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Moving on to step 11:
The number 921 fits into 8330 9 times, leaving a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 8554.3279
If we take 8289 away from 8330, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 12:
410 divided by 921 is 0 with a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 8554.3279
If we subtract 0 from 410, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

On to step 13:
921 can be fit into 4100 4 times, resulting in a remainder of 416.
Record the quotient 4 as the next digit in the result. 
Result so far: 8554.327904
If we subtract 3684 from 4100, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Step 14:
If we divide 4160 by 921, we get 4 and a remainder of 476.
The next digit of our result is 4. 
Result so far: 8554.3279044
If we subtract 3684 from 4160, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Our division results in 8554.3279044 with a remaining 4.76e-06.
