We're dividing 17642574 by 921 
Our goal is to divide 17642574 by 921.

Let's proceed to step 1:
The number 921 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 921

Moving on to step 2:
921 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 921

On to step 3:
921 can be fit into 176 0 times, resulting in a remainder of 176.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 176 and we're left with 176.
Grab the next digit (4) from the dividend, add it to 176, then carry on: 1764 / 921

Moving on to step 4:
The number 921 fits into 1764 1 times, leaving a remainder of 843.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 921 away from 1764, we end up with 843.
Append the next digit (2) from the dividend to 843 and continue with: 8432 / 921

Moving on to step 5:
If we divide 8432 by 921, we get 9 and a remainder of 143.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 8289 from 8432 and we're left with 143.
Bring next digit (5) of the dividend behind the 143 and repeat the process: 1435 / 921

On to step 6:
1435 divided by 921 is 1 with a remainder of 514.
The number 1 becomes the next digit in our result. 
Result so far: 191.0
Subtracting 921 from 1435 leaves us with 514.
Bring next digit (7) of the dividend behind the 514 and repeat the process: 5147 / 921

Let's proceed to step 7:
5147 divided by 921 is 5 with a remainder of 542.
Put 5 as the next digit of the answer. 
Result so far: 1915.0
If we take 4605 away from 5147, we end up with 542.
Take the next digit (4) from the dividend and append it to 542, then repeat: 5424 / 921

Step 8:
When dividing 5424 by 921, we get 5 with a remainder of 819.
The next digit of our result is 5. 
Result so far: 19155.0
If we take 4605 away from 5424, we end up with 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Going ahead to step 9:
921 can be fit into 8190 8 times, resulting in a remainder of 822.
Record the quotient 8 as the next digit in the result. 
Result so far: 19155.8
If we subtract 7368 from 8190, we get 822.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8220, and continue the process.

Advancing to step 10:
The number 921 fits into 8220 8 times, leaving a remainder of 852.
The number 8 becomes the next digit in our result. 
Result so far: 19155.88
Deduct 7368 from 8220 and we're left with 852.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8520, and continue the process.

The final result is 19155.88 with a remainder of 0.852.
