We divide 802720 by 79
The aim is to understand the frequency of 79 in 802720.

Going ahead to step 1:
If we divide 8 by 79, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 79

Advancing to step 2:
79 can be fit into 80 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 79 from 80 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 79

Step 3:
79 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 79

Advancing to step 4:
79 can be fit into 127 1 times, resulting in a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtracting 79 from 127 leaves us with 48.
Take the next digit (2) from the dividend and append it to 48, then repeat: 482 / 79

Moving on to step 5:
If we divide 482 by 79, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1016.0
Subtract 474 from 482 to get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 79

Advancing to step 6:
When dividing 80 by 79, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 10161.0
The remainder is 1 after subtracting 79 from 80.
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 7:
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: 10161.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 79 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 10161.01
If we take 79 away from 100, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
When dividing 210 by 79, we get 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 10161.012
Deduct 158 from 210 and we're left 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.

Step 10:
When dividing 520 by 79, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 10161.0126
The remainder is 46 after subtracting 474 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
460 divided by 79 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 10161.01265
Subtract 395 from 460 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 12:
If we divide 650 by 79, we get 8 and a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 10161.012658
If we take 632 away from 650, we end up 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.

Step 13:
When dividing 180 by 79, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 10161.0126582
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.

Let's proceed to step 14:
79 goes into 220 2 times with a remainder of 62.
The number 2 becomes the next digit in our result. 
Result so far: 10161.01265822
Deduct 158 from 220 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 10161.01265822 and a remainder of 6.2e-08.
