849705 ÷ 15 
The aim is to understand the frequency of 15 in 849705.

Let's proceed to step 1:
15 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 15

Going ahead to step 2:
If we divide 84 by 15, we get 5 and a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 75 away from 84, we end up with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 15

Advancing to step 3:
15 goes into 99 6 times with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 90 away from 99, we end up with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 15

On to step 4:
If we divide 97 by 15, we get 6 and a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
The remainder is 7 after subtracting 90 from 97.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 15

On to step 5:
15 goes into 70 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 5664.0
Subtract 60 from 70 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 15

On to step 6:
15 can be fit into 105 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 56647.0
Subtracting 105 from 105 leaves us 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 7:
0 divided by 15 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 56647.0
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.

Advancing 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: 56647.0
Subtract 0 from 0 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.

The final outcome is 56647.0, with a leftover of 0.0.
