We look at the division of 42633397 by 79 
The aim is to understand the frequency of 79 in 42633397.

Advancing to step 1:
79 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 79

Step 2:
When dividing 42 by 79, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (6) from the dividend after 42, then repeat: 426 / 79

Moving on to step 3:
426 divided by 79 is 5 with a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 395 from 426 to get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 79

On to step 4:
313 divided by 79 is 3 with a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtract 237 from 313 to get 76.
Append the next digit (3) from the dividend to 76 and continue with: 763 / 79

Going ahead to step 5:
The number 79 fits into 763 9 times, leaving a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 539.0
Deduct 711 from 763 and we're left with 52.
Append the next digit (3) from the dividend to 52 and continue with: 523 / 79

Let's proceed to step 6:
79 goes into 523 6 times with a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 5396.0
If we subtract 474 from 523, we get 49.
Include the next digit (9) from the dividend after 49, then repeat: 499 / 79

Advancing to step 7:
499 divided by 79 is 6 with a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 53966.0
The remainder is 25 after subtracting 474 from 499.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 79

On to step 8:
257 divided by 79 is 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 539663.0
Deduct 237 from 257 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.

Advancing to step 9:
79 can be fit into 200 2 times, resulting in a remainder of 42.
Write down 2 as next digit of the result. 
Result so far: 539663.2
If we subtract 158 from 200, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
79 can be fit into 420 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 539663.25
Subtract 395 from 420 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
When dividing 250 by 79, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 539663.253
If we take 237 away from 250, we end up 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.

Going ahead to step 12:
When dividing 130 by 79, we get 1 with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 539663.2531
The remainder is 51 after subtracting 79 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
79 can be fit into 510 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 539663.25316
Subtract 474 from 510 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 14:
360 divided by 79 is 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 539663.253164
If we subtract 316 from 360, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 15:
If we divide 440 by 79, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 539663.2531645
The remainder is 45 after subtracting 395 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 16:
79 can be fit into 450 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 539663.25316455
The remainder is 55 after subtracting 395 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 539663.25316455 with a remainder of 5.5e-08.
