We're dividing 311944 by 15 
The aim is to understand the frequency of 15 in 311944.

Let's proceed to step 1:
3 divided by 15 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 15

Step 2:
The number 15 fits into 31 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 30 from 31, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 15

Moving on to step 3:
15 can be fit into 11 0 times, resulting in a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtracting 0 from 11 leaves us with 11.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 15

Moving on to step 4:
The number 15 fits into 119 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 207.0
Deduct 105 from 119 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 15

Advancing to step 5:
The number 15 fits into 144 9 times, leaving a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 2079.0
Subtract 135 from 144 to get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 15

Moving on to step 6:
When dividing 94 by 15, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 20796.0
The remainder is 4 after subtracting 90 from 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 15, we get 2 and a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 20796.2
If we take 30 away from 40, we end up 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.

Step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 20796.26
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.

Going ahead to step 9:
15 goes into 100 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 20796.266
Deduct 90 from 100 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.

After the division, we end up with 20796.266 and a remainder of 0.001.
