78351175 divided by 315 
The aim is to understand the frequency of 315 in 78351175.

Let's proceed to step 1:
When dividing 7 by 315, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 315

Going ahead to step 2:
When dividing 78 by 315, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 315

Going ahead to step 3:
If we divide 783 by 315, we get 2 and a remainder of 153.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 630 from 783, we get 153.
Grab the next digit (5) from the dividend, add it to 153, then carry on: 1535 / 315

Going ahead to step 4:
The number 315 fits into 1535 4 times, leaving a remainder of 275.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 1260 from 1535, we get 275.
Append the next digit (1) from the dividend to 275 and continue with: 2751 / 315

Moving on to step 5:
2751 divided by 315 is 8 with a remainder of 231.
Write down 8 as next digit of the result. 
Result so far: 248.0
If we take 2520 away from 2751, we end up with 231.
Take the next digit (1) from the dividend and append it to 231, then repeat: 2311 / 315

Let's proceed to step 6:
315 goes into 2311 7 times with a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 2487.0
If we take 2205 away from 2311, we end up with 106.
Grab the next digit (7) from the dividend, add it to 106, then carry on: 1067 / 315

Advancing to step 7:
315 goes into 1067 3 times with a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 24873.0
Deduct 945 from 1067 and we're left with 122.
Grab the next digit (5) from the dividend, add it to 122, then carry on: 1225 / 315

Let's proceed to step 8:
315 can be fit into 1225 3 times, resulting in a remainder of 280.
Write down 3 as next digit of the result. 
Result so far: 248733.0
Deduct 945 from 1225 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.

Going ahead to step 9:
If we divide 2800 by 315, we get 8 and a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 248733.8
Subtracting 2520 from 2800 leaves us 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.

Step 10:
2800 divided by 315 is 8 with a remainder of 280.
The number 8 becomes the next digit in our result. 
Result so far: 248733.88
If we subtract 2520 from 2800, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 248733.88 and a remainder of 0.28.
