173724 divided by 72 
We're looking to find how many times 72 goes into 173724.

Step 1:
1 divided by 72 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 72

Let's proceed to step 2:
If we divide 17 by 72, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 72

On to step 3:
72 goes into 173 2 times with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 144 from 173 and we're left with 29.
Grab the next digit (7) from the dividend, add it to 29, then carry on: 297 / 72

Advancing to step 4:
If we divide 297 by 72, we get 4 and a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we subtract 288 from 297, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 72

Advancing to step 5:
The number 72 fits into 92 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 241.0
Subtract 72 from 92 to get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 72

Going ahead to step 6:
204 divided by 72 is 2 with a remainder of 60.
The number 2 becomes the next digit in our result. 
Result so far: 2412.0
The remainder is 60 after subtracting 144 from 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
When dividing 600 by 72, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 2412.8
The remainder is 24 after subtracting 576 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
If we divide 240 by 72, we get 3 and a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 2412.83
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
240 divided by 72 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 2412.833
The remainder is 24 after subtracting 216 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 2412.833 and a remainder of 0.0024.
