We're dividing 233943 by 79 
The aim is to understand the frequency of 79 in 233943.

Advancing to step 1:
2 divided by 79 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 79

Advancing to step 2:
23 divided by 79 is 0 with a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 79

Moving on to step 3:
79 can be fit into 233 2 times, resulting in a remainder of 75.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 75 after subtracting 158 from 233.
Grab the next digit (9) from the dividend, add it to 75, then carry on: 759 / 79

Going ahead to step 4:
759 divided by 79 is 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 711 from 759 and we're left with 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 79

Moving on to step 5:
If we divide 484 by 79, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 296.0
Deduct 474 from 484 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 79

Moving on to step 6:
79 can be fit into 103 1 times, resulting in a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 2961.0
If we subtract 79 from 103, we 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.

Going ahead to step 7:
79 can be fit into 240 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 2961.3
Deduct 237 from 240 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
The number 79 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 2961.3
Subtracting 0 from 30 leaves us 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.

Going ahead to step 9:
300 divided by 79 is 3 with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 2961.303
Subtracting 237 from 300 leaves us with 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 10:
The number 79 fits into 630 7 times, leaving a remainder of 77.
The next digit of our result is 7. 
Result so far: 2961.3037
The remainder is 77 after subtracting 553 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 11:
79 can be fit into 770 9 times, resulting in a remainder of 59.
The next digit of our result is 9. 
Result so far: 2961.30379
Deduct 711 from 770 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 12:
The number 79 fits into 590 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 2961.303797
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.

Going ahead to step 13:
370 divided by 79 is 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 2961.3037974
If we take 316 away from 370, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
79 goes into 540 6 times with a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 2961.30379746
The remainder is 66 after subtracting 474 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 2961.30379746 with a remainder of 6.6e-08.
