We look at the division of 420260 by 79 
The aim is to understand the frequency of 79 in 420260.

Step 1:
79 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 79

Going ahead to step 2:
79 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 79

Moving on to step 3:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 395 from 420 to get 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 79

Moving on to step 4:
79 goes into 252 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we subtract 237 from 252, we get 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 79

Advancing to step 5:
156 divided by 79 is 1 with a remainder of 77.
The number 1 becomes the next digit in our result. 
Result so far: 531.0
If we take 79 away from 156, we end up with 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 79

Going ahead to step 6:
79 can be fit into 770 9 times, resulting in a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 5319.0
Subtract 711 from 770 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
If we divide 590 by 79, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 5319.7
Subtracting 553 from 590 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 8:
79 can be fit into 370 4 times, resulting in a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 5319.74
The remainder is 54 after subtracting 316 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
When dividing 540 by 79, we get 6 with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 5319.746
If we take 474 away from 540, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 10:
If we divide 660 by 79, we get 8 and a remainder of 28.
The next digit of our result is 8. 
Result so far: 5319.7468
If we subtract 632 from 660, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
79 can be fit into 280 3 times, resulting in a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 5319.74683
Subtract 237 from 280 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 12:
430 divided by 79 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5319.746835
Subtracting 395 from 430 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
If we divide 350 by 79, we get 4 and a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 5319.7468354
If we subtract 316 from 350, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
When dividing 340 by 79, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 5319.74683544
Subtract 316 from 340 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 5319.74683544 with a remaining 2.4e-08.
