201598 divided by 15 
The aim is to understand the frequency of 15 in 201598.

On to step 1:
15 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 15

Let's proceed to step 2:
20 divided by 15 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 15 from 20 to get 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 15

Step 3:
When dividing 51 by 15, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 45 from 51 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 15

Step 4:
65 divided by 15 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 134.0
The remainder is 5 after subtracting 60 from 65.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 15

Let's proceed to step 5:
If we divide 59 by 15, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 1343.0
If we take 45 away from 59, we end up with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 15

Advancing to step 6:
If we divide 148 by 15, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 13439.0
The remainder is 13 after subtracting 135 from 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 15 fits into 130 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 13439.8
The remainder is 10 after subtracting 120 from 130.
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 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 13439.86
If we take 90 away from 100, 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.

Let's proceed to step 9:
100 divided by 15 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 13439.866
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.

Our division results in 13439.866 with a remaining 0.001.
