199398 divided by 79 
The aim is to understand the frequency of 79 in 199398.

On to step 1:
When dividing 1 by 79, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 79

Moving on to step 2:
If we divide 19 by 79, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 79

Let's proceed to step 3:
The number 79 fits into 199 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 158 from 199, we get 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 79

Advancing to step 4:
413 divided by 79 is 5 with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 395 away from 413, we end up with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 79

Advancing to step 5:
79 goes into 189 2 times with a remainder of 31.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Subtract 158 from 189 to get 31.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 79

Let's proceed to step 6:
79 goes into 318 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 2524.0
If we subtract 316 from 318, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
79 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2524.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 79 fits into 200 2 times, leaving a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 2524.02
If we take 158 away from 200, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
If we divide 420 by 79, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 2524.025
If we subtract 395 from 420, we 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.

Advancing to step 10:
When dividing 250 by 79, we get 3 with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 2524.0253
The remainder is 13 after subtracting 237 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 11:
If we divide 130 by 79, we get 1 and a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 2524.02531
If we subtract 79 from 130, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 12:
79 can be fit into 510 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 2524.025316
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.

Step 13:
79 can be fit into 360 4 times, resulting in a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 2524.0253164
The remainder is 44 after subtracting 316 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 14:
If we divide 440 by 79, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 2524.02531645
If we subtract 395 from 440, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Our division results in 2524.02531645 with a remaining 4.5e-08.
