We divide 721316 by 79
The aim is to understand the frequency of 79 in 721316.

Let's proceed to step 1:
When dividing 7 by 79, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 79

Moving on to step 2:
79 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 72 after subtracting 0 from 72.
Fetch the next digit (1) from the dividend, attach it to 72 and continue: 721 / 79

Moving on to step 3:
When dividing 721 by 79, we get 9 with a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 711 from 721, we get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 79

On to step 4:
103 divided by 79 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtracting 79 from 103 leaves us with 24.
Take the next digit (1) from the dividend and append it to 24, then repeat: 241 / 79

Let's proceed to step 5:
The number 79 fits into 241 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 913.0
The remainder is 4 after subtracting 237 from 241.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 79

Going ahead to step 6:
79 goes into 46 0 times with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 9130.0
The remainder is 46 after subtracting 0 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
The number 79 fits into 460 5 times, leaving a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 9130.5
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.

Going ahead to step 8:
650 divided by 79 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 9130.58
Subtracting 632 from 650 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
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: 9130.582
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.

On to step 10:
If we divide 220 by 79, we get 2 and a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 9130.5822
The remainder is 62 after subtracting 158 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 9130.5822 with a remainder of 0.00062.
