15173 ÷ 72 
We're looking to find how many times 72 goes into 15173.

Let's proceed to step 1:
The number 72 fits into 1 0 times, leaving 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.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 72

Let's proceed to step 2:
If we divide 15 by 72, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 72

Step 3:
151 divided by 72 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 7 after subtracting 144 from 151.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 72

Moving on to step 4:
72 goes into 77 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 5 after subtracting 72 from 77.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 72

Step 5:
72 can be fit into 53 0 times, resulting in a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 210.0
If we take 0 away from 53, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 6:
If we divide 530 by 72, we get 7 and a remainder of 26.
The next digit of our result is 7. 
Result so far: 210.7
Subtracting 504 from 530 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
If we divide 260 by 72, we get 3 and a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 210.73
Deduct 216 from 260 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
72 goes into 440 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 210.736
Deduct 432 from 440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 9:
If we divide 80 by 72, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 210.7361
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 72, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 210.73611
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 210.73611 with a balance of 8e-06.
