We look at the division of 36615583 by 79 
The aim is to understand the frequency of 79 in 36615583.

On to step 1:
79 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 79

Going ahead to step 2:
79 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 36, we end up with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 79

Going ahead to step 3:
366 divided by 79 is 4 with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 316 from 366 leaves us with 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 79

Moving on to step 4:
501 divided by 79 is 6 with a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtracting 474 from 501 leaves us with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 79

Going ahead to step 5:
79 goes into 275 3 times with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 463.0
Deduct 237 from 275 and we're left with 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 79

Moving on to step 6:
385 divided by 79 is 4 with a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 4634.0
Deduct 316 from 385 and we're left with 69.
Append the next digit (8) from the dividend to 69 and continue with: 698 / 79

Let's proceed to step 7:
79 can be fit into 698 8 times, resulting in a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 46348.0
Subtract 632 from 698 to get 66.
Take the next digit (3) from the dividend and append it to 66, then repeat: 663 / 79

On to step 8:
If we divide 663 by 79, we get 8 and a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 463488.0
If we subtract 632 from 663, 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.

On to step 9:
79 goes into 310 3 times with a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 463488.3
Deduct 237 from 310 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 10:
79 can be fit into 730 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 463488.39
Subtract 711 from 730 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
If we divide 190 by 79, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 463488.392
Subtract 158 from 190 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
79 can be fit into 320 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 463488.3924
Deduct 316 from 320 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
The number 79 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 463488.3924
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 14:
400 divided by 79 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 463488.392405
Subtract 395 from 400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 15:
79 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 463488.392405
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 16:
79 can be fit into 500 6 times, resulting in a remainder of 26.
The next digit of our result is 6. 
Result so far: 463488.39240506
Subtract 474 from 500 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 463488.39240506 with a remainder of 2.6e-08.
