We're dividing 634515 by 72 
The aim is to understand the frequency of 72 in 634515.

On to step 1:
6 divided by 72 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 72

On to step 2:
63 divided by 72 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 72

Advancing to step 3:
72 can be fit into 634 8 times, resulting in a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 576 from 634 leaves us with 58.
Grab the next digit (5) from the dividend, add it to 58, then carry on: 585 / 72

On to step 4:
72 can be fit into 585 8 times, resulting in a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtracting 576 from 585 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 72

Moving on to step 5:
The number 72 fits into 91 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 881.0
If we take 72 away from 91, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 72

Going ahead to step 6:
72 can be fit into 195 2 times, resulting in a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 8812.0
The remainder is 51 after subtracting 144 from 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
72 goes into 510 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 8812.7
Deduct 504 from 510 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
The number 72 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 8812.7
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
72 can be fit into 600 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 8812.708
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.

Advancing to step 10:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 8812.7083
Deduct 216 from 240 and we're left 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.

Step 11:
The number 72 fits into 240 3 times, leaving a remainder of 24.
The next digit of our result is 3. 
Result so far: 8812.70833
If we take 216 away from 240, we end up 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.

The quotient of the division is 8812.70833, and the remainder is 2.4e-05.
