We look at the division of 42315 by 79 
The aim is to understand the frequency of 79 in 42315.

Let's proceed to step 1:
4 divided by 79 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 79

On to step 2:
The number 79 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 79

Step 3:
If we divide 423 by 79, we get 5 and a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 395 away from 423, we end up with 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 79

Let's proceed to step 4:
If we divide 281 by 79, we get 3 and a remainder of 44.
Write down 3 as next digit of the result. 
Result so far: 53.0
The remainder is 44 after subtracting 237 from 281.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 79

Going ahead to step 5:
79 goes into 445 5 times with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 535.0
If we subtract 395 from 445, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 6:
The number 79 fits into 500 6 times, leaving a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 535.6
If we take 474 away from 500, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 7:
The number 79 fits into 260 3 times, leaving a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 535.63
If we subtract 237 from 260, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
79 can be fit into 230 2 times, resulting in a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 535.632
If we take 158 away from 230, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
If we divide 720 by 79, we get 9 and a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 535.6329
If we subtract 711 from 720, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
79 can be fit into 90 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 535.63291
Deduct 79 from 90 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
79 can be fit into 110 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 535.632911
If we take 79 away from 110, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The quotient of the division is 535.632911, and the remainder is 3.1e-06.
