Let's divide 674064 by 15
The aim is to understand the frequency of 15 in 674064.

Moving on to step 1:
15 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 15

Moving on to step 2:
If we divide 67 by 15, we get 4 and a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 7 after subtracting 60 from 67.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 15

Going ahead to step 3:
If we divide 74 by 15, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtracting 60 from 74 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 15

On to step 4:
15 can be fit into 140 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 449.0
Subtract 135 from 140 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 15

Advancing to step 5:
56 divided by 15 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 4493.0
If we subtract 45 from 56, we get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 15

On to step 6:
15 can be fit into 114 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 44937.0
If we take 105 away from 114, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
15 can be fit into 90 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 44937.6
Subtract 90 from 90 to 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.

Step 8:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 44937.6
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.

Moving on to step 9:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 44937.6
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 44937.6, and the remainder is 0.0.
