Let's divide 677370 by 15
The aim is to understand the frequency of 15 in 677370.

Let's proceed to step 1:
If we divide 6 by 15, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 15

Step 2:
The number 15 fits into 67 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 60 from 67 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 15

Moving on to step 3:
15 can be fit into 77 5 times, resulting in a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 45.0
If we subtract 75 from 77, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 15

Going ahead to step 4:
When dividing 23 by 15, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 451.0
Subtracting 15 from 23 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 15

Step 5:
15 goes into 87 5 times with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 4515.0
If we take 75 away from 87, we end up with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 15

On to step 6:
120 divided by 15 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 45158.0
If we take 120 away from 120, we end up 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.

Step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 45158.0
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.

On to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 45158.0
Deduct 0 from 0 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.

The quotient of the division is 45158.0, and the remainder is 0.0.
