We look at the division of 225711 by 79 
The aim is to understand the frequency of 79 in 225711.

Let's proceed to step 1:
79 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 79

On to step 2:
79 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 79

Advancing to step 3:
79 can be fit into 225 2 times, resulting in a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 158 from 225 and we're left with 67.
Bring next digit (7) of the dividend behind the 67 and repeat the process: 677 / 79

Step 4:
79 can be fit into 677 8 times, resulting in a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 632 from 677 and we're left with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 79

Advancing to step 5:
451 divided by 79 is 5 with a remainder of 56.
Use 5 as the next digit of our solution. 
Result so far: 285.0
Subtracting 395 from 451 leaves us with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 79

Advancing to step 6:
79 goes into 561 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 2857.0
Subtract 553 from 561 to get 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 7:
When dividing 80 by 79, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 2857.1
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.

On to step 8:
If we divide 10 by 79, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 2857.1
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
If we divide 100 by 79, we get 1 and a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 2857.101
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.

Advancing to step 10:
210 divided by 79 is 2 with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 2857.1012
Subtracting 158 from 210 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
520 divided by 79 is 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 2857.10126
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.

Step 12:
The number 79 fits into 460 5 times, leaving a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 2857.101265
If we take 395 away from 460, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
If we divide 650 by 79, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 2857.1012658
Subtract 632 from 650 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
The number 79 fits into 180 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 2857.10126582
Subtract 158 from 180 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 2857.10126582 with a balance of 2.2e-08.
