We're dividing 581115 by 79 
The aim is to understand the frequency of 79 in 581115.

Going ahead to step 1:
When dividing 5 by 79, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 79

Let's proceed to step 2:
58 divided by 79 is 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 79

Going ahead to step 3:
581 divided by 79 is 7 with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 553 from 581 to get 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 79

Going ahead to step 4:
When dividing 281 by 79, we get 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 44 after subtracting 237 from 281.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 79

On to step 5:
If we divide 441 by 79, we get 5 and a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 735.0
If we take 395 away from 441, we end up with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 79

Advancing to step 6:
79 goes into 465 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 7355.0
If we take 395 away from 465, we end up 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 7:
700 divided by 79 is 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 7355.8
Subtracting 632 from 700 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
The number 79 fits into 680 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 7355.88
If we subtract 632 from 680, we 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.

The final result is 7355.88 with a remainder of 0.048.
