We look at the division of 15122052 by 915 
The aim is to understand the frequency of 915 in 15122052.

Going ahead to step 1:
915 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 915

Advancing to step 2:
915 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 915

On to step 3:
151 divided by 915 is 0 with a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 151 after subtracting 0 from 151.
Bring next digit (2) of the dividend behind the 151 and repeat the process: 1512 / 915

On to step 4:
The number 915 fits into 1512 1 times, leaving a remainder of 597.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 915 from 1512 to get 597.
Bring next digit (2) of the dividend behind the 597 and repeat the process: 5972 / 915

Advancing to step 5:
915 goes into 5972 6 times with a remainder of 482.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 5490 from 5972 to get 482.
Take the next digit (0) from the dividend and append it to 482, then repeat: 4820 / 915

On to step 6:
915 goes into 4820 5 times with a remainder of 245.
Use 5 as the next digit of our solution. 
Result so far: 165.0
If we take 4575 away from 4820, we end up with 245.
Grab the next digit (5) from the dividend, add it to 245, then carry on: 2455 / 915

Let's proceed to step 7:
2455 divided by 915 is 2 with a remainder of 625.
The number 2 becomes the next digit in our result. 
Result so far: 1652.0
If we subtract 1830 from 2455, we get 625.
Include the next digit (2) from the dividend after 625, then repeat: 6252 / 915

Let's proceed to step 8:
915 goes into 6252 6 times with a remainder of 762.
The next digit of our result is 6. 
Result so far: 16526.0
If we subtract 5490 from 6252, we get 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 9:
If we divide 7620 by 915, we get 8 and a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 16526.8
Deduct 7320 from 7620 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 10:
The number 915 fits into 3000 3 times, leaving a remainder of 255.
The next digit of our result is 3. 
Result so far: 16526.83
If we take 2745 away from 3000, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 11:
2550 divided by 915 is 2 with a remainder of 720.
Record the quotient 2 as the next digit in the result. 
Result so far: 16526.832
The remainder is 720 after subtracting 1830 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Let's proceed to step 12:
915 goes into 7200 7 times with a remainder of 795.
The next digit of our result is 7. 
Result so far: 16526.8327
The remainder is 795 after subtracting 6405 from 7200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

On to step 13:
If we divide 7950 by 915, we get 8 and a remainder of 630.
The number 8 becomes the next digit in our result. 
Result so far: 16526.83278
The remainder is 630 after subtracting 7320 from 7950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 14:
The number 915 fits into 6300 6 times, leaving a remainder of 810.
Record the quotient 6 as the next digit in the result. 
Result so far: 16526.832786
Deduct 5490 from 6300 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Advancing to step 15:
The number 915 fits into 8100 8 times, leaving a remainder of 780.
Put 8 as the next digit of the answer. 
Result so far: 16526.8327868
If we take 7320 away from 8100, we end up with 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Going ahead to step 16:
The number 915 fits into 7800 8 times, leaving a remainder of 480.
Use 8 as the next digit of our solution. 
Result so far: 16526.83278688
Subtracting 7320 from 7800 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Our division results in 16526.83278688 with a remaining 4.8e-07.
