72989005 divided by 921 
We want to divide 72989005 by 921.

Step 1:
921 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 921

Moving on to step 2:
921 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (9) of the dividend behind the 72 and repeat the process: 729 / 921

Moving on to step 3:
729 divided by 921 is 0 with a remainder of 729.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 729 and we're left with 729.
Include the next digit (8) from the dividend after 729, then repeat: 7298 / 921

Let's proceed to step 4:
When dividing 7298 by 921, we get 7 with a remainder of 851.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we take 6447 away from 7298, we end up with 851.
Fetch the next digit (9) from the dividend, attach it to 851 and continue: 8519 / 921

Going ahead to step 5:
If we divide 8519 by 921, we get 9 and a remainder of 230.
The next digit of our result is 9. 
Result so far: 79.0
Subtract 8289 from 8519 to get 230.
Fetch the next digit (0) from the dividend, attach it to 230 and continue: 2300 / 921

On to step 6:
921 can be fit into 2300 2 times, resulting in a remainder of 458.
Write down 2 as next digit of the result. 
Result so far: 792.0
If we subtract 1842 from 2300, we get 458.
Include the next digit (0) from the dividend after 458, then repeat: 4580 / 921

Step 7:
The number 921 fits into 4580 4 times, leaving a remainder of 896.
Put 4 as the next digit of the answer. 
Result so far: 7924.0
If we subtract 3684 from 4580, we get 896.
Take the next digit (5) from the dividend and append it to 896, then repeat: 8965 / 921

Step 8:
8965 divided by 921 is 9 with a remainder of 676.
The next digit of our result is 9. 
Result so far: 79249.0
Subtracting 8289 from 8965 leaves us with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Moving on to step 9:
921 goes into 6760 7 times with a remainder of 313.
The next digit of our result is 7. 
Result so far: 79249.7
The remainder is 313 after subtracting 6447 from 6760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Step 10:
If we divide 3130 by 921, we get 3 and a remainder of 367.
Put 3 as the next digit of the answer. 
Result so far: 79249.73
Subtract 2763 from 3130 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 11:
921 goes into 3670 3 times with a remainder of 907.
The next digit of our result is 3. 
Result so far: 79249.733
Subtracting 2763 from 3670 leaves us with 907.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9070, and continue the process.

The final result is 79249.733 with a remainder of 0.0907.
