We look at the division of 15955824 by 679 
The aim is to understand the frequency of 679 in 15955824.

Moving on to step 1:
679 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 679

Let's proceed to step 2:
15 divided by 679 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 679

Advancing to step 3:
159 divided by 679 is 0 with a remainder of 159.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 159, we end up with 159.
Bring next digit (5) of the dividend behind the 159 and repeat the process: 1595 / 679

Going ahead to step 4:
When dividing 1595 by 679, we get 2 with a remainder of 237.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1358 away from 1595, we end up with 237.
Append the next digit (5) from the dividend to 237 and continue with: 2375 / 679

On to step 5:
679 goes into 2375 3 times with a remainder of 338.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 2037 from 2375 leaves us with 338.
Bring next digit (8) of the dividend behind the 338 and repeat the process: 3388 / 679

Advancing to step 6:
The number 679 fits into 3388 4 times, leaving a remainder of 672.
The next digit of our result is 4. 
Result so far: 234.0
Subtract 2716 from 3388 to get 672.
Fetch the next digit (2) from the dividend, attach it to 672 and continue: 6722 / 679

Moving on to step 7:
6722 divided by 679 is 9 with a remainder of 611.
Write down 9 as next digit of the result. 
Result so far: 2349.0
The remainder is 611 after subtracting 6111 from 6722.
Take the next digit (4) from the dividend and append it to 611, then repeat: 6114 / 679

Moving on to step 8:
6114 divided by 679 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 23499.0
If we take 6111 away from 6114, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
The number 679 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 23499.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
The number 679 fits into 300 0 times, leaving a remainder of 300.
Use 0 as the next digit of our solution. 
Result so far: 23499.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 23499.0 with a remaining 0.3.
