We look at the division of 323572 by 79 
The aim is to understand the frequency of 79 in 323572.

On to step 1:
79 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 79

Going ahead to step 2:
79 goes into 32 0 times with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 79

Step 3:
79 goes into 323 4 times with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 316 from 323 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 79

Advancing to step 4:
75 divided by 79 is 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Deduct 0 from 75 and we're left with 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 79

Let's proceed to step 5:
757 divided by 79 is 9 with a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 409.0
Subtracting 711 from 757 leaves us with 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 79

Going ahead to step 6:
When dividing 462 by 79, we get 5 with a remainder of 67.
Write down 5 as next digit of the result. 
Result so far: 4095.0
If we take 395 away from 462, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
670 divided by 79 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 4095.8
If we take 632 away from 670, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
When dividing 380 by 79, we get 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 4095.84
The remainder is 64 after subtracting 316 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
640 divided by 79 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 4095.848
If we take 632 away from 640, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
79 goes into 80 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 4095.8481
If we subtract 79 from 80, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
The number 79 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 4095.8481
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
If we divide 100 by 79, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 4095.848101
The remainder is 21 after subtracting 79 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 13:
79 can be fit into 210 2 times, resulting in a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 4095.8481012
Subtract 158 from 210 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
When dividing 520 by 79, we get 6 with a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 4095.84810126
Subtract 474 from 520 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 4095.84810126, with a leftover of 4.6e-08.
