We look at the division of 624267 by 79 
The aim is to understand the frequency of 79 in 624267.

Step 1:
The number 79 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 79

Moving on to step 2:
62 divided by 79 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (4) from the dividend and append it to 62, then repeat: 624 / 79

Advancing to step 3:
79 goes into 624 7 times with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 71 after subtracting 553 from 624.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 79

Going ahead to step 4:
712 divided by 79 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtracting 711 from 712 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 79

On to step 5:
When dividing 16 by 79, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 790.0
Subtracting 0 from 16 leaves us with 16.
Take the next digit (7) from the dividend and append it to 16, then repeat: 167 / 79

On to step 6:
If we divide 167 by 79, we get 2 and a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 7902.0
Subtract 158 from 167 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
79 goes into 90 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 7902.1
If we subtract 79 from 90, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 8:
The number 79 fits into 110 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 7902.11
If we subtract 79 from 110, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 7902.11 and a remainder of 0.031.
