We're dividing 714558 by 15 
The aim is to understand the frequency of 15 in 714558.

Going ahead to step 1:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 15

Step 2:
When dividing 71 by 15, we get 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 60 from 71 and we're left with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 15

Step 3:
15 can be fit into 114 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 47.0
The remainder is 9 after subtracting 105 from 114.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 15

Step 4:
95 divided by 15 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 476.0
Subtract 90 from 95 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 15

Advancing to step 5:
When dividing 55 by 15, we get 3 with a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 4763.0
The remainder is 10 after subtracting 45 from 55.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 15

Advancing to step 6:
108 divided by 15 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 47637.0
If we subtract 105 from 108, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
If we divide 30 by 15, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 47637.2
Deduct 30 from 30 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 47637.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 47637.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 47637.2 with a remaining 0.0.
