15486725 divided by 315 
The aim is to understand the frequency of 315 in 15486725.

On to step 1:
1 divided by 315 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 315

Moving on to step 2:
When dividing 15 by 315, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 315

Going ahead to step 3:
315 goes into 154 0 times with a remainder of 154.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 154, we get 154.
Include the next digit (8) from the dividend after 154, then repeat: 1548 / 315

Moving on to step 4:
The number 315 fits into 1548 4 times, leaving a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 288 after subtracting 1260 from 1548.
Include the next digit (6) from the dividend after 288, then repeat: 2886 / 315

Moving on to step 5:
When dividing 2886 by 315, we get 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 49.0
Deduct 2835 from 2886 and we're left with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 315

Advancing to step 6:
315 can be fit into 517 1 times, resulting in a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 491.0
Subtracting 315 from 517 leaves us with 202.
Bring next digit (2) of the dividend behind the 202 and repeat the process: 2022 / 315

Step 7:
When dividing 2022 by 315, we get 6 with a remainder of 132.
Record the quotient 6 as the next digit in the result. 
Result so far: 4916.0
If we take 1890 away from 2022, we end up with 132.
Append the next digit (5) from the dividend to 132 and continue with: 1325 / 315

Advancing to step 8:
315 can be fit into 1325 4 times, resulting in a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 49164.0
Subtracting 1260 from 1325 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
The number 315 fits into 650 2 times, leaving a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 49164.2
If we subtract 630 from 650, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
The number 315 fits into 200 0 times, leaving a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 49164.2
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 11:
If we divide 2000 by 315, we get 6 and a remainder of 110.
The number 6 becomes the next digit in our result. 
Result so far: 49164.206
The remainder is 110 after subtracting 1890 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 12:
315 can be fit into 1100 3 times, resulting in a remainder of 155.
Write down 3 as next digit of the result. 
Result so far: 49164.2063
Deduct 945 from 1100 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Moving on to step 13:
If we divide 1550 by 315, we get 4 and a remainder of 290.
Write down 4 as next digit of the result. 
Result so far: 49164.20634
Deduct 1260 from 1550 and we're left with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 14:
2900 divided by 315 is 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 49164.206349
Subtract 2835 from 2900 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 15:
When dividing 650 by 315, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 49164.2063492
The remainder is 20 after subtracting 630 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
315 can be fit into 200 0 times, resulting in a remainder of 200.
The next digit of our result is 0. 
Result so far: 49164.2063492
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final outcome is 49164.2063492, with a leftover of 2e-07.
