17149904 ÷ 921 
Let's see how many times 921 fits into 17149904.

Moving on to step 1:
921 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 921

Let's proceed to step 2:
17 divided by 921 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 921

Going ahead to step 3:
The number 921 fits into 171 0 times, leaving a remainder of 171.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 171, we end up with 171.
Bring next digit (4) of the dividend behind the 171 and repeat the process: 1714 / 921

On to step 4:
1714 divided by 921 is 1 with a remainder of 793.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 921 from 1714 and we're left with 793.
Take the next digit (9) from the dividend and append it to 793, then repeat: 7939 / 921

Let's proceed to step 5:
When dividing 7939 by 921, we get 8 with a remainder of 571.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtract 7368 from 7939 to get 571.
Bring next digit (9) of the dividend behind the 571 and repeat the process: 5719 / 921

Moving on to step 6:
The number 921 fits into 5719 6 times, leaving a remainder of 193.
The next digit of our result is 6. 
Result so far: 186.0
Deduct 5526 from 5719 and we're left with 193.
Include the next digit (0) from the dividend after 193, then repeat: 1930 / 921

Let's proceed to step 7:
921 goes into 1930 2 times with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 1862.0
Subtract 1842 from 1930 to get 88.
Bring next digit (4) of the dividend behind the 88 and repeat the process: 884 / 921

On to step 8:
921 goes into 884 0 times with a remainder of 884.
The next digit of our result is 0. 
Result so far: 18620.0
The remainder is 884 after subtracting 0 from 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

On to step 9:
921 can be fit into 8840 9 times, resulting in a remainder of 551.
Record the quotient 9 as the next digit in the result. 
Result so far: 18620.9
The remainder is 551 after subtracting 8289 from 8840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Let's proceed to step 10:
If we divide 5510 by 921, we get 5 and a remainder of 905.
Write down 5 as next digit of the result. 
Result so far: 18620.95
Subtracting 4605 from 5510 leaves us with 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Let's proceed to step 11:
921 can be fit into 9050 9 times, resulting in a remainder of 761.
Record the quotient 9 as the next digit in the result. 
Result so far: 18620.959
Deduct 8289 from 9050 and we're left with 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

Let's proceed to step 12:
If we divide 7610 by 921, we get 8 and a remainder of 242.
Put 8 as the next digit of the answer. 
Result so far: 18620.9598
If we take 7368 away from 7610, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 13:
921 goes into 2420 2 times with a remainder of 578.
The next digit of our result is 2. 
Result so far: 18620.95982
If we subtract 1842 from 2420, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 14:
When dividing 5780 by 921, we get 6 with a remainder of 254.
The number 6 becomes the next digit in our result. 
Result so far: 18620.959826
Deduct 5526 from 5780 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 15:
2540 divided by 921 is 2 with a remainder of 698.
Put 2 as the next digit of the answer. 
Result so far: 18620.9598262
If we take 1842 away from 2540, we end up with 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Moving on to step 16:
The number 921 fits into 6980 7 times, leaving a remainder of 533.
The number 7 becomes the next digit in our result. 
Result so far: 18620.95982627
If we take 6447 away from 6980, we end up with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

In conclusion, the division gives 18620.95982627 with a balance of 5.33e-07.
