344644 ÷ 72 
We want to divide 344644 by 72.

On to step 1:
3 divided by 72 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 72

Going ahead to step 2:
If we divide 34 by 72, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 72

On to step 3:
The number 72 fits into 344 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 288 away from 344, we end up with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 72

Going ahead to step 4:
The number 72 fits into 566 7 times, leaving a remainder of 62.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 504 from 566, we get 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 72

Going ahead to step 5:
If we divide 624 by 72, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 478.0
Subtracting 576 from 624 leaves us with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 72

Advancing to step 6:
72 goes into 484 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 4786.0
If we take 432 away from 484, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 7:
If we divide 520 by 72, we get 7 and a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 4786.7
Subtracting 504 from 520 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
If we divide 160 by 72, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4786.72
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 72, we get 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 4786.722
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4786.722 and a remainder of 0.0016.
