16447424 ÷ 615 
The aim is to understand the frequency of 615 in 16447424.

Moving on to step 1:
If we divide 1 by 615, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 615

Going ahead to step 2:
When dividing 16 by 615, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 615

Going ahead to step 3:
If we divide 164 by 615, we get 0 and a remainder of 164.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 164, we get 164.
Take the next digit (4) from the dividend and append it to 164, then repeat: 1644 / 615

Advancing to step 4:
1644 divided by 615 is 2 with a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 414 after subtracting 1230 from 1644.
Fetch the next digit (7) from the dividend, attach it to 414 and continue: 4147 / 615

On to step 5:
The number 615 fits into 4147 6 times, leaving a remainder of 457.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 3690 from 4147, we get 457.
Take the next digit (4) from the dividend and append it to 457, then repeat: 4574 / 615

Let's proceed to step 6:
If we divide 4574 by 615, we get 7 and a remainder of 269.
Record the quotient 7 as the next digit in the result. 
Result so far: 267.0
Subtracting 4305 from 4574 leaves us with 269.
Append the next digit (2) from the dividend to 269 and continue with: 2692 / 615

Going ahead to step 7:
2692 divided by 615 is 4 with a remainder of 232.
The number 4 becomes the next digit in our result. 
Result so far: 2674.0
Subtracting 2460 from 2692 leaves us with 232.
Include the next digit (4) from the dividend after 232, then repeat: 2324 / 615

Let's proceed to step 8:
When dividing 2324 by 615, we get 3 with a remainder of 479.
The next digit of our result is 3. 
Result so far: 26743.0
If we subtract 1845 from 2324, we get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Step 9:
615 goes into 4790 7 times with a remainder of 485.
Put 7 as the next digit of the answer. 
Result so far: 26743.7
The remainder is 485 after subtracting 4305 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 10:
The number 615 fits into 4850 7 times, leaving a remainder of 545.
The next digit of our result is 7. 
Result so far: 26743.77
If we subtract 4305 from 4850, we get 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

Our division results in 26743.77 with a remaining 0.545.
