We're dividing 31973118 by 315 
The aim is to understand the frequency of 315 in 31973118.

Moving on to step 1:
315 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 315

Going ahead to step 2:
When dividing 31 by 315, we get 0 with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (9) from the dividend, attach it to 31 and continue: 319 / 315

Let's proceed to step 3:
The number 315 fits into 319 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 315 from 319, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 315

Going ahead to step 4:
If we divide 47 by 315, we get 0 and a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 47, we get 47.
Include the next digit (3) from the dividend after 47, then repeat: 473 / 315

On to step 5:
The number 315 fits into 473 1 times, leaving a remainder of 158.
The next digit of our result is 1. 
Result so far: 101.0
If we take 315 away from 473, we end up with 158.
Take the next digit (1) from the dividend and append it to 158, then repeat: 1581 / 315

Going ahead to step 6:
If we divide 1581 by 315, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 1015.0
If we take 1575 away from 1581, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 315

Moving on to step 7:
The number 315 fits into 61 0 times, leaving a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 10150.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 315

Step 8:
618 divided by 315 is 1 with a remainder of 303.
Put 1 as the next digit of the answer. 
Result so far: 101501.0
Subtract 315 from 618 to get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 9:
3030 divided by 315 is 9 with a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 101501.9
Subtract 2835 from 3030 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 10:
The number 315 fits into 1950 6 times, leaving a remainder of 60.
Write down 6 as next digit of the result. 
Result so far: 101501.96
If we take 1890 away from 1950, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
600 divided by 315 is 1 with a remainder of 285.
The next digit of our result is 1. 
Result so far: 101501.961
Deduct 315 from 600 and we're left 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.

Going ahead to step 12:
If we divide 2850 by 315, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 101501.9619
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.

Advancing to step 13:
If we divide 150 by 315, we get 0 and a remainder of 150.
Record the quotient 0 as the next digit in the result. 
Result so far: 101501.9619
If we subtract 0 from 150, 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.

Advancing to step 14:
315 can be fit into 1500 4 times, resulting in a remainder of 240.
The number 4 becomes the next digit in our result. 
Result so far: 101501.961904
Subtracting 1260 from 1500 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 15:
When dividing 2400 by 315, we get 7 with a remainder of 195.
Put 7 as the next digit of the answer. 
Result so far: 101501.9619047
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.

Advancing to step 16:
The number 315 fits into 1950 6 times, leaving a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 101501.96190476
If we take 1890 away from 1950, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 101501.96190476 with a remaining 6e-08.
