21170845 divided by 722 
We want to divide 21170845 by 722.

Let's proceed to step 1:
The number 722 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 722

Let's proceed to step 2:
21 divided by 722 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 722

Going ahead to step 3:
722 goes into 211 0 times with a remainder of 211.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 211 to get 211.
Grab the next digit (7) from the dividend, add it to 211, then carry on: 2117 / 722

Let's proceed to step 4:
722 can be fit into 2117 2 times, resulting in a remainder of 673.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1444 from 2117 to get 673.
Bring next digit (0) of the dividend behind the 673 and repeat the process: 6730 / 722

Step 5:
When dividing 6730 by 722, we get 9 with a remainder of 232.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
If we subtract 6498 from 6730, we get 232.
Bring next digit (8) of the dividend behind the 232 and repeat the process: 2328 / 722

Advancing to step 6:
If we divide 2328 by 722, we get 3 and a remainder of 162.
Write down 3 as next digit of the result. 
Result so far: 293.0
Subtract 2166 from 2328 to get 162.
Append the next digit (4) from the dividend to 162 and continue with: 1624 / 722

Moving on to step 7:
The number 722 fits into 1624 2 times, leaving a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 2932.0
Subtract 1444 from 1624 to get 180.
Bring next digit (5) of the dividend behind the 180 and repeat the process: 1805 / 722

Step 8:
722 can be fit into 1805 2 times, resulting in a remainder of 361.
Use 2 as the next digit of our solution. 
Result so far: 29322.0
If we take 1444 away from 1805, we end up with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
3610 divided by 722 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 29322.5
Subtracting 3610 from 3610 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
0 divided by 722 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29322.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 722 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29322.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 29322.5 with a remainder of 0.0.
