We look at the division of 315734 by 72 
The aim is to understand the frequency of 72 in 315734.

On to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 72

Going ahead to step 2:
If we divide 31 by 72, we get 0 and a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 72

Going ahead to step 3:
72 goes into 315 4 times with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 27 after subtracting 288 from 315.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 72

Step 4:
277 divided by 72 is 3 with a remainder of 61.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we take 216 away from 277, we end up with 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 72

Let's proceed to step 5:
The number 72 fits into 613 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 438.0
The remainder is 37 after subtracting 576 from 613.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 72

Going ahead to step 6:
72 goes into 374 5 times with a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 4385.0
Subtracting 360 from 374 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 72 is 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 4385.1
Deduct 72 from 140 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 8:
If we divide 680 by 72, we get 9 and a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 4385.19
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
72 goes into 320 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 4385.194
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
72 can be fit into 320 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 4385.1944
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 4385.1944 and a remainder of 0.00032.
