We divide 21321338 by 724
We want to figure out the number of times 21321338 can be divided by 724.

On to step 1:
724 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 724

Let's proceed to step 2:
724 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 724

Advancing to step 3:
If we divide 213 by 724, we get 0 and a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 213 to get 213.
Fetch the next digit (2) from the dividend, attach it to 213 and continue: 2132 / 724

Going ahead to step 4:
724 can be fit into 2132 2 times, resulting in a remainder of 684.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1448 away from 2132, we end up with 684.
Bring next digit (1) of the dividend behind the 684 and repeat the process: 6841 / 724

Advancing to step 5:
724 goes into 6841 9 times with a remainder of 325.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtract 6516 from 6841 to get 325.
Grab the next digit (3) from the dividend, add it to 325, then carry on: 3253 / 724

Let's proceed to step 6:
724 goes into 3253 4 times with a remainder of 357.
The number 4 becomes the next digit in our result. 
Result so far: 294.0
Subtracting 2896 from 3253 leaves us with 357.
Bring next digit (3) of the dividend behind the 357 and repeat the process: 3573 / 724

On to step 7:
If we divide 3573 by 724, we get 4 and a remainder of 677.
Use 4 as the next digit of our solution. 
Result so far: 2944.0
If we subtract 2896 from 3573, we get 677.
Append the next digit (8) from the dividend to 677 and continue with: 6778 / 724

Step 8:
6778 divided by 724 is 9 with a remainder of 262.
The next digit of our result is 9. 
Result so far: 29449.0
Deduct 6516 from 6778 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 9:
The number 724 fits into 2620 3 times, leaving a remainder of 448.
The number 3 becomes the next digit in our result. 
Result so far: 29449.3
Deduct 2172 from 2620 and we're left with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 10:
When dividing 4480 by 724, we get 6 with a remainder of 136.
Record the quotient 6 as the next digit in the result. 
Result so far: 29449.36
Deduct 4344 from 4480 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 11:
When dividing 1360 by 724, we get 1 with a remainder of 636.
Put 1 as the next digit of the answer. 
Result so far: 29449.361
Subtract 724 from 1360 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

On to step 12:
When dividing 6360 by 724, we get 8 with a remainder of 568.
Write down 8 as next digit of the result. 
Result so far: 29449.3618
Subtracting 5792 from 6360 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 13:
724 goes into 5680 7 times with a remainder of 612.
Record the quotient 7 as the next digit in the result. 
Result so far: 29449.36187
Subtract 5068 from 5680 to get 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 14:
724 can be fit into 6120 8 times, resulting in a remainder of 328.
The next digit of our result is 8. 
Result so far: 29449.361878
Deduct 5792 from 6120 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 15:
3280 divided by 724 is 4 with a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 29449.3618784
If we subtract 2896 from 3280, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 16:
If we divide 3840 by 724, we get 5 and a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 29449.36187845
Subtracting 3620 from 3840 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 29449.36187845 and a remainder of 2.2e-07.
