We're dividing 198241 by 79 
The aim is to understand the frequency of 79 in 198241.

Step 1:
If we divide 1 by 79, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 79

On to step 2:
The number 79 fits into 19 0 times, leaving a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 79

Advancing to step 3:
198 divided by 79 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 158 from 198 to get 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 79

Advancing to step 4:
When dividing 402 by 79, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 395 away from 402, we end up with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 79

Let's proceed to step 5:
79 can be fit into 74 0 times, resulting in a remainder of 74.
The number 0 becomes the next digit in our result. 
Result so far: 250.0
Subtracting 0 from 74 leaves us with 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 79

Step 6:
741 divided by 79 is 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 2509.0
If we take 711 away from 741, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
79 can be fit into 300 3 times, resulting in a remainder of 63.
The next digit of our result is 3. 
Result so far: 2509.3
Subtract 237 from 300 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 8:
79 can be fit into 630 7 times, resulting in a remainder of 77.
The next digit of our result is 7. 
Result so far: 2509.37
Deduct 553 from 630 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
The number 79 fits into 770 9 times, leaving a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 2509.379
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.

Moving on to step 10:
When dividing 590 by 79, we get 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 2509.3797
If we take 553 away from 590, we end up 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.

Step 11:
79 can be fit into 370 4 times, resulting in a remainder of 54.
The next digit of our result is 4. 
Result so far: 2509.37974
Subtract 316 from 370 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
The number 79 fits into 540 6 times, leaving a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 2509.379746
If we subtract 474 from 540, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 13:
79 can be fit into 660 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 2509.3797468
If we take 632 away from 660, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
79 goes into 280 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 2509.37974683
If we subtract 237 from 280, we 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.

After the division, we end up with 2509.37974683 and a remainder of 4.3e-08.
