We look at the division of 947375 by 72 
The aim is to understand the frequency of 72 in 947375.

Going ahead to step 1:
72 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 72

Going ahead to step 2:
94 divided by 72 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 72 away from 94, we end up with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 72

Moving on to step 3:
The number 72 fits into 227 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 216 from 227, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 72

Moving on to step 4:
72 can be fit into 113 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 131.0
The remainder is 41 after subtracting 72 from 113.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 72

Moving on to step 5:
If we divide 417 by 72, we get 5 and a remainder of 57.
The next digit of our result is 5. 
Result so far: 1315.0
Deduct 360 from 417 and we're left with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 72

Moving on to step 6:
If we divide 575 by 72, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 13157.0
Subtract 504 from 575 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
72 can be fit into 710 9 times, resulting in a remainder of 62.
The next digit of our result is 9. 
Result so far: 13157.9
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 8:
72 can be fit into 620 8 times, resulting in a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 13157.98
The remainder is 44 after subtracting 576 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
When dividing 440 by 72, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 13157.986
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
72 goes into 80 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 13157.9861
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
72 can be fit into 80 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 13157.98611
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 13157.98611, and the remainder is 8e-06.
