We're dividing 85630406 by 315 
The aim is to understand the frequency of 315 in 85630406.

On to step 1:
If we divide 8 by 315, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 315

Let's proceed to step 2:
If we divide 85 by 315, we get 0 and a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Fetch the next digit (6) from the dividend, attach it to 85 and continue: 856 / 315

Advancing to step 3:
856 divided by 315 is 2 with a remainder of 226.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 630 from 856 leaves us with 226.
Include the next digit (3) from the dividend after 226, then repeat: 2263 / 315

Let's proceed to step 4:
315 goes into 2263 7 times with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 2205 away from 2263, we end up with 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 315

Let's proceed to step 5:
580 divided by 315 is 1 with a remainder of 265.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
Subtract 315 from 580 to get 265.
Include the next digit (4) from the dividend after 265, then repeat: 2654 / 315

Advancing to step 6:
When dividing 2654 by 315, we get 8 with a remainder of 134.
Write down 8 as next digit of the result. 
Result so far: 2718.0
Deduct 2520 from 2654 and we're left with 134.
Include the next digit (0) from the dividend after 134, then repeat: 1340 / 315

Step 7:
1340 divided by 315 is 4 with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 27184.0
If we take 1260 away from 1340, we end up with 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 315

On to step 8:
When dividing 806 by 315, we get 2 with a remainder of 176.
Put 2 as the next digit of the answer. 
Result so far: 271842.0
Subtract 630 from 806 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 9:
If we divide 1760 by 315, we get 5 and a remainder of 185.
Use 5 as the next digit of our solution. 
Result so far: 271842.5
The remainder is 185 after subtracting 1575 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 10:
The number 315 fits into 1850 5 times, leaving a remainder of 275.
The next digit of our result is 5. 
Result so far: 271842.55
The remainder is 275 after subtracting 1575 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

The final outcome is 271842.55, with a leftover of 0.275.
