We divide 221695 by 15
The aim is to understand the frequency of 15 in 221695.

Step 1:
15 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 15

Moving on to step 2:
15 can be fit into 22 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 15 from 22 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 15

Moving on to step 3:
The number 15 fits into 71 4 times, leaving a remainder of 11.
The next digit of our result is 4. 
Result so far: 14.0
If we subtract 60 from 71, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 15

On to step 4:
If we divide 116 by 15, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
Subtracting 105 from 116 leaves us with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 15

Moving on to step 5:
When dividing 119 by 15, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 1477.0
Deduct 105 from 119 and we're left with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 15

On to step 6:
If we divide 145 by 15, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 14779.0
Deduct 135 from 145 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 14779.6
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 14779.66
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 14779.66 with a balance of 0.01.
