We look at the division of 634781 by 72 
The aim is to understand the frequency of 72 in 634781.

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
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 72

Going ahead to step 2:
72 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 72

Going ahead to step 3:
The number 72 fits into 634 8 times, leaving a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 576 from 634 to get 58.
Append the next digit (7) from the dividend to 58 and continue with: 587 / 72

Going ahead to step 4:
If we divide 587 by 72, we get 8 and a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
Subtracting 576 from 587 leaves us with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 72

Going ahead to step 5:
118 divided by 72 is 1 with a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 881.0
Subtract 72 from 118 to get 46.
Fetch the next digit (1) from the dividend, attach it to 46 and continue: 461 / 72

Moving on to step 6:
If we divide 461 by 72, we get 6 and a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 8816.0
If we take 432 away from 461, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
72 can be fit into 290 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 8816.4
Subtracting 288 from 290 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 72, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8816.4
Deduct 0 from 20 and we're left 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.

Moving on to step 9:
200 divided by 72 is 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 8816.402
The remainder is 56 after subtracting 144 from 200.
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 10:
The number 72 fits into 560 7 times, leaving a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 8816.4027
Deduct 504 from 560 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 11:
The number 72 fits into 560 7 times, leaving a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 8816.40277
Deduct 504 from 560 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.

Our division results in 8816.40277 with a remaining 5.6e-05.
