We're dividing 15320203 by 915 
The aim is to understand the frequency of 915 in 15320203.

Step 1:
915 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 915

Moving on to step 2:
If we divide 15 by 915, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 915

On to step 3:
If we divide 153 by 915, we get 0 and a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 153 after subtracting 0 from 153.
Include the next digit (2) from the dividend after 153, then repeat: 1532 / 915

Going ahead to step 4:
When dividing 1532 by 915, we get 1 with a remainder of 617.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 915 away from 1532, we end up with 617.
Bring next digit (0) of the dividend behind the 617 and repeat the process: 6170 / 915

Let's proceed to step 5:
The number 915 fits into 6170 6 times, leaving a remainder of 680.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 5490 away from 6170, we end up with 680.
Take the next digit (2) from the dividend and append it to 680, then repeat: 6802 / 915

Going ahead to step 6:
915 can be fit into 6802 7 times, resulting in a remainder of 397.
Use 7 as the next digit of our solution. 
Result so far: 167.0
The remainder is 397 after subtracting 6405 from 6802.
Append the next digit (0) from the dividend to 397 and continue with: 3970 / 915

Let's proceed to step 7:
The number 915 fits into 3970 4 times, leaving a remainder of 310.
The next digit of our result is 4. 
Result so far: 1674.0
Subtract 3660 from 3970 to get 310.
Include the next digit (3) from the dividend after 310, then repeat: 3103 / 915

Let's proceed to step 8:
3103 divided by 915 is 3 with a remainder of 358.
The next digit of our result is 3. 
Result so far: 16743.0
Deduct 2745 from 3103 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 9:
915 can be fit into 3580 3 times, resulting in a remainder of 835.
Record the quotient 3 as the next digit in the result. 
Result so far: 16743.3
Subtract 2745 from 3580 to get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Moving on to step 10:
If we divide 8350 by 915, we get 9 and a remainder of 115.
The number 9 becomes the next digit in our result. 
Result so far: 16743.39
Deduct 8235 from 8350 and we're left with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 11:
If we divide 1150 by 915, we get 1 and a remainder of 235.
Write down 1 as next digit of the result. 
Result so far: 16743.391
Subtract 915 from 1150 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 12:
If we divide 2350 by 915, we get 2 and a remainder of 520.
Use 2 as the next digit of our solution. 
Result so far: 16743.3912
The remainder is 520 after subtracting 1830 from 2350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 13:
915 goes into 5200 5 times with a remainder of 625.
The number 5 becomes the next digit in our result. 
Result so far: 16743.39125
The remainder is 625 after subtracting 4575 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

On to step 14:
6250 divided by 915 is 6 with a remainder of 760.
The number 6 becomes the next digit in our result. 
Result so far: 16743.391256
Subtract 5490 from 6250 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 15:
915 can be fit into 7600 8 times, resulting in a remainder of 280.
Record the quotient 8 as the next digit in the result. 
Result so far: 16743.3912568
Deduct 7320 from 7600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 16:
If we divide 2800 by 915, we get 3 and a remainder of 55.
The next digit of our result is 3. 
Result so far: 16743.39125683
If we take 2745 away from 2800, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 16743.39125683, with a leftover of 5.5e-08.
