Let's divide 721211 by 79
The aim is to understand the frequency of 79 in 721211.

Step 1:
When dividing 7 by 79, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 79

Let's proceed to step 2:
72 divided by 79 is 0 with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 79

Advancing to step 3:
If we divide 721 by 79, we get 9 and a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 711 from 721 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 79

Moving on to step 4:
79 goes into 102 1 times with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 23 after subtracting 79 from 102.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 79

On to step 5:
When dividing 231 by 79, we get 2 with a remainder of 73.
The next digit of our result is 2. 
Result so far: 912.0
If we subtract 158 from 231, we get 73.
Grab the next digit (1) from the dividend, add it to 73, then carry on: 731 / 79

Advancing to step 6:
If we divide 731 by 79, we get 9 and a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 9129.0
Deduct 711 from 731 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
When dividing 200 by 79, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 9129.2
Subtracting 158 from 200 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
420 divided by 79 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9129.25
Subtract 395 from 420 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
The number 79 fits into 250 3 times, leaving a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 9129.253
If we take 237 away from 250, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
79 can be fit into 130 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 9129.2531
Deduct 79 from 130 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 11:
When dividing 510 by 79, we get 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 9129.25316
Subtract 474 from 510 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
79 can be fit into 360 4 times, resulting in a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 9129.253164
If we take 316 away from 360, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
The number 79 fits into 440 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9129.2531645
Deduct 395 from 440 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 14:
450 divided by 79 is 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 9129.25316455
Subtract 395 from 450 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 9129.25316455 with a remainder of 5.5e-08.
