We look at the division of 376560 by 15 
The aim is to understand the frequency of 15 in 376560.

Moving on to step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 15

Going ahead to step 2:
15 can be fit into 37 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 30 from 37 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 15

Advancing to step 3:
15 goes into 76 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 75 from 76 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 15

Moving on to step 4:
15 divided by 15 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 251.0
If we take 15 away from 15, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 15

Going ahead to step 5:
15 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 2510.0
If we subtract 0 from 6, we get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 15

Going ahead to step 6:
60 divided by 15 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 25104.0
If we subtract 60 from 60, we get 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 7:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25104.0
If we subtract 0 from 0, we get 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 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25104.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 25104.0, and the remainder is 0.0.
