We're dividing 40339305 by 315 
The aim is to understand the frequency of 315 in 40339305.

Moving on to step 1:
4 divided by 315 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 315

Advancing to step 2:
315 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 315

Going ahead to step 3:
The number 315 fits into 403 1 times, leaving a remainder of 88.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 315 from 403 to get 88.
Include the next digit (3) from the dividend after 88, then repeat: 883 / 315

Step 4:
When dividing 883 by 315, we get 2 with a remainder of 253.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 630 from 883, we get 253.
Append the next digit (9) from the dividend to 253 and continue with: 2539 / 315

Advancing to step 5:
If we divide 2539 by 315, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we take 2520 away from 2539, we end up with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 315

Let's proceed to step 6:
The number 315 fits into 193 0 times, leaving a remainder of 193.
The next digit of our result is 0. 
Result so far: 1280.0
Subtract 0 from 193 to get 193.
Fetch the next digit (0) from the dividend, attach it to 193 and continue: 1930 / 315

Advancing to step 7:
The number 315 fits into 1930 6 times, leaving a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 12806.0
If we subtract 1890 from 1930, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 315

Moving on to step 8:
405 divided by 315 is 1 with a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 128061.0
If we subtract 315 from 405, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 9:
900 divided by 315 is 2 with a remainder of 270.
Use 2 as the next digit of our solution. 
Result so far: 128061.2
If we take 630 away from 900, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 10:
When dividing 2700 by 315, we get 8 with a remainder of 180.
The next digit of our result is 8. 
Result so far: 128061.28
If we take 2520 away from 2700, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
The number 315 fits into 1800 5 times, leaving a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 128061.285
Subtracting 1575 from 1800 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 12:
2250 divided by 315 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 128061.2857
If we take 2205 away from 2250, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 13:
315 goes into 450 1 times with a remainder of 135.
Record the quotient 1 as the next digit in the result. 
Result so far: 128061.28571
Subtracting 315 from 450 leaves us with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 14:
315 can be fit into 1350 4 times, resulting in a remainder of 90.
Use 4 as the next digit of our solution. 
Result so far: 128061.285714
If we take 1260 away from 1350, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 15:
When dividing 900 by 315, we get 2 with a remainder of 270.
Write down 2 as next digit of the result. 
Result so far: 128061.2857142
Subtracting 630 from 900 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 16:
315 can be fit into 2700 8 times, resulting in a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 128061.28571428
Subtract 2520 from 2700 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final outcome is 128061.28571428, with a leftover of 1.8e-07.
