We divide 845552 by 15
The aim is to understand the frequency of 15 in 845552.

Going ahead to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 15

Step 2:
The number 15 fits into 84 5 times, leaving a remainder of 9.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 9 after subtracting 75 from 84.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 15

Going ahead to step 3:
The number 15 fits into 95 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 56.0
Subtract 90 from 95 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 15

Moving on to step 4:
55 divided by 15 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 563.0
Subtracting 45 from 55 leaves us with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 15

Going ahead to step 5:
When dividing 105 by 15, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 5637.0
Deduct 105 from 105 and we're left with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 15

Advancing to step 6:
15 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 56370.0
The remainder is 2 after subtracting 0 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 15 fits into 20 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 56370.1
If we take 15 away from 20, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 56370.13
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 56370.133
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 56370.133, with a leftover of 0.0005.
