We look at the division of 315452 by 72 
We want to figure out the number of times 315452 can be divided by 72.

Advancing to step 1:
3 divided by 72 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 72

Going ahead to step 2:
If we divide 31 by 72, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 72

Going ahead to step 3:
72 goes into 315 4 times with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 288 from 315 and we're left with 27.
Bring next digit (4) of the dividend behind the 27 and repeat the process: 274 / 72

Advancing to step 4:
The number 72 fits into 274 3 times, leaving a remainder of 58.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 216 from 274 leaves us with 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 72

Moving on to step 5:
The number 72 fits into 585 8 times, leaving a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 438.0
If we subtract 576 from 585, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 72

Going ahead to step 6:
If we divide 92 by 72, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 4381.0
Subtracting 72 from 92 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
72 can be fit into 200 2 times, resulting in a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 4381.2
Deduct 144 from 200 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
560 divided by 72 is 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 4381.27
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
If we divide 560 by 72, we get 7 and a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 4381.277
If we subtract 504 from 560, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 4381.277, and the remainder is 0.0056.
