We look at the division of 712619 by 79 
The aim is to understand the frequency of 79 in 712619.

On to step 1:
If we divide 7 by 79, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 79

Going ahead to step 2:
79 can be fit into 71 0 times, resulting in a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 71 leaves us with 71.
Grab the next digit (2) from the dividend, add it to 71, then carry on: 712 / 79

Going ahead to step 3:
The number 79 fits into 712 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 711 from 712 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 79

Moving on to step 4:
If we divide 16 by 79, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 90.0
If we subtract 0 from 16, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 79

Going ahead to step 5:
The number 79 fits into 161 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 902.0
The remainder is 3 after subtracting 158 from 161.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 79

Let's proceed to step 6:
79 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 9020.0
Deduct 0 from 39 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
79 can be fit into 390 4 times, resulting in a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 9020.4
Deduct 316 from 390 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
When dividing 740 by 79, we get 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 9020.49
If we take 711 away from 740, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
If we divide 290 by 79, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 9020.493
Subtracting 237 from 290 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 10:
If we divide 530 by 79, we get 6 and a remainder of 56.
Write down 6 as next digit of the result. 
Result so far: 9020.4936
Deduct 474 from 530 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
79 goes into 560 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 9020.49367
If we take 553 away from 560, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
70 divided by 79 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 9020.49367
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 13:
The number 79 fits into 700 8 times, leaving a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 9020.4936708
The remainder is 68 after subtracting 632 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
If we divide 680 by 79, we get 8 and a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 9020.49367088
Deduct 632 from 680 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 9020.49367088, with a leftover of 4.8e-08.
