Let's divide 398072 by 79
The aim is to understand the frequency of 79 in 398072.

Step 1:
The number 79 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 79

Going ahead to step 2:
If we divide 39 by 79, we get 0 and a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 79

Let's proceed to step 3:
When dividing 398 by 79, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 3 after subtracting 395 from 398.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 79

Step 4:
If we divide 30 by 79, we get 0 and a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 30, we get 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 79

Going ahead to step 5:
79 can be fit into 307 3 times, resulting in a remainder of 70.
The next digit of our result is 3. 
Result so far: 503.0
If we take 237 away from 307, we end up with 70.
Append the next digit (2) from the dividend to 70 and continue with: 702 / 79

Advancing to step 6:
702 divided by 79 is 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 5038.0
Subtracting 632 from 702 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.

On to step 7:
79 can be fit into 700 8 times, resulting in a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 5038.8
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.

Step 8:
79 can be fit into 680 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 5038.88
Subtract 632 from 680 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 5038.88 and a remainder of 0.048.
