17864668 divided by 921 
We want to figure out the number of times 17864668 can be divided by 921.

Moving on to step 1:
When dividing 1 by 921, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 921

Advancing to step 2:
921 can be fit into 17 0 times, resulting in a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 921

Let's proceed to step 3:
When dividing 178 by 921, we get 0 with a remainder of 178.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 178, we get 178.
Append the next digit (6) from the dividend to 178 and continue with: 1786 / 921

Moving on to step 4:
921 can be fit into 1786 1 times, resulting in a remainder of 865.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 921 from 1786, we get 865.
Grab the next digit (4) from the dividend, add it to 865, then carry on: 8654 / 921

Let's proceed to step 5:
When dividing 8654 by 921, we get 9 with a remainder of 365.
The next digit of our result is 9. 
Result so far: 19.0
If we take 8289 away from 8654, we end up with 365.
Take the next digit (6) from the dividend and append it to 365, then repeat: 3656 / 921

Advancing to step 6:
When dividing 3656 by 921, we get 3 with a remainder of 893.
The next digit of our result is 3. 
Result so far: 193.0
Subtracting 2763 from 3656 leaves us with 893.
Take the next digit (6) from the dividend and append it to 893, then repeat: 8936 / 921

Going ahead to step 7:
The number 921 fits into 8936 9 times, leaving a remainder of 647.
The number 9 becomes the next digit in our result. 
Result so far: 1939.0
The remainder is 647 after subtracting 8289 from 8936.
Fetch the next digit (8) from the dividend, attach it to 647 and continue: 6478 / 921

Going ahead to step 8:
6478 divided by 921 is 7 with a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 19397.0
If we subtract 6447 from 6478, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 9:
The number 921 fits into 310 0 times, leaving a remainder of 310.
The number 0 becomes the next digit in our result. 
Result so far: 19397.0
Subtracting 0 from 310 leaves us with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 10:
When dividing 3100 by 921, we get 3 with a remainder of 337.
The number 3 becomes the next digit in our result. 
Result so far: 19397.03
Subtract 2763 from 3100 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Let's proceed to step 11:
921 can be fit into 3370 3 times, resulting in a remainder of 607.
Record the quotient 3 as the next digit in the result. 
Result so far: 19397.033
If we subtract 2763 from 3370, we get 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

The final outcome is 19397.033, with a leftover of 0.0607.
