We're dividing 637789 by 72 
The aim is to understand the frequency of 72 in 637789.

Going ahead to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 72

Let's proceed 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
Deduct 0 from 63 and we're left with 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 72

Moving on to step 3:
72 goes into 637 8 times with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 576 from 637, we get 61.
Fetch the next digit (7) from the dividend, attach it to 61 and continue: 617 / 72

Moving on to step 4:
72 goes into 617 8 times with a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Subtract 576 from 617 to get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 72

Moving on to step 5:
72 can be fit into 418 5 times, resulting in a remainder of 58.
Record the quotient 5 as the next digit in the result. 
Result so far: 885.0
The remainder is 58 after subtracting 360 from 418.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 72

Advancing to step 6:
The number 72 fits into 589 8 times, leaving a remainder of 13.
The next digit of our result is 8. 
Result so far: 8858.0
Subtracting 576 from 589 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
72 goes into 130 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 8858.1
If we take 72 away from 130, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
72 can be fit into 580 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 8858.18
Subtracting 576 from 580 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 72 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8858.18
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
When dividing 400 by 72, we get 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 8858.1805
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
When dividing 400 by 72, we get 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 8858.18055
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 8858.18055 with a remaining 4e-05.
