10378383 ÷ 315 
The aim is to understand the frequency of 315 in 10378383.

Let's proceed to step 1:
If we divide 1 by 315, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 315

Going ahead to step 2:
315 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 315

Going ahead to step 3:
When dividing 103 by 315, we get 0 with a remainder of 103.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 103 leaves us with 103.
Bring next digit (7) of the dividend behind the 103 and repeat the process: 1037 / 315

Advancing to step 4:
315 can be fit into 1037 3 times, resulting in a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 945 from 1037 leaves us with 92.
Bring next digit (8) of the dividend behind the 92 and repeat the process: 928 / 315

Let's proceed to step 5:
The number 315 fits into 928 2 times, leaving a remainder of 298.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
The remainder is 298 after subtracting 630 from 928.
Include the next digit (3) from the dividend after 298, then repeat: 2983 / 315

On to step 6:
If we divide 2983 by 315, we get 9 and a remainder of 148.
Put 9 as the next digit of the answer. 
Result so far: 329.0
Subtracting 2835 from 2983 leaves us with 148.
Bring next digit (8) of the dividend behind the 148 and repeat the process: 1488 / 315

Going ahead to step 7:
The number 315 fits into 1488 4 times, leaving a remainder of 228.
Use 4 as the next digit of our solution. 
Result so far: 3294.0
Subtract 1260 from 1488 to get 228.
Append the next digit (3) from the dividend to 228 and continue with: 2283 / 315

Let's proceed to step 8:
315 goes into 2283 7 times with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 32947.0
If we subtract 2205 from 2283, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
315 goes into 780 2 times with a remainder of 150.
Use 2 as the next digit of our solution. 
Result so far: 32947.2
If we subtract 630 from 780, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
The number 315 fits into 1500 4 times, leaving a remainder of 240.
The next digit of our result is 4. 
Result so far: 32947.24
If we subtract 1260 from 1500, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
2400 divided by 315 is 7 with a remainder of 195.
The number 7 becomes the next digit in our result. 
Result so far: 32947.247
The remainder is 195 after subtracting 2205 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Moving on to step 12:
When dividing 1950 by 315, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 32947.2476
Subtract 1890 from 1950 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
315 goes into 600 1 times with a remainder of 285.
Write down 1 as next digit of the result. 
Result so far: 32947.24761
Subtracting 315 from 600 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 14:
The number 315 fits into 2850 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 32947.247619
The remainder is 15 after subtracting 2835 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 15:
150 divided by 315 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 32947.247619
Subtracting 0 from 150 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 16:
When dividing 1500 by 315, we get 4 with a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 32947.24761904
Subtract 1260 from 1500 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Our division results in 32947.24761904 with a remaining 2.4e-07.
