We look at the division of 831566 by 79 
The aim is to understand the frequency of 79 in 831566.

Moving on to step 1:
79 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 79

Moving on to step 2:
When dividing 83 by 79, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 79 from 83, we get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 79

Moving on to step 3:
79 can be fit into 41 0 times, resulting in a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 41, we get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 79

Let's proceed to step 4:
415 divided by 79 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtracting 395 from 415 leaves us with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 79

Advancing to step 5:
79 can be fit into 206 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 1052.0
The remainder is 48 after subtracting 158 from 206.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 79

Step 6:
When dividing 486 by 79, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10526.0
Subtract 474 from 486 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
120 divided by 79 is 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 10526.1
The remainder is 41 after subtracting 79 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
79 can be fit into 410 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 10526.15
If we subtract 395 from 410, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 79 is 1 with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 10526.151
If we take 79 away from 150, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 10:
When dividing 710 by 79, we get 8 with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 10526.1518
Deduct 632 from 710 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
If we divide 780 by 79, we get 9 and a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 10526.15189
Subtracting 711 from 780 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
If we divide 690 by 79, we get 8 and a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 10526.151898
Deduct 632 from 690 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 13:
If we divide 580 by 79, we get 7 and a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 10526.1518987
Deduct 553 from 580 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
When dividing 270 by 79, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 10526.15189873
Deduct 237 from 270 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 10526.15189873, with a leftover of 3.3e-08.
