We're dividing 15137502 by 297 
The aim is to understand the frequency of 297 in 15137502.

On to step 1:
1 divided by 297 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 297

Advancing to step 2:
When dividing 15 by 297, we get 0 with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 297

Going ahead to step 3:
If we divide 151 by 297, we get 0 and a remainder of 151.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Append the next digit (3) from the dividend to 151 and continue with: 1513 / 297

Advancing to step 4:
When dividing 1513 by 297, we get 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 28 after subtracting 1485 from 1513.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 297

On to step 5:
287 divided by 297 is 0 with a remainder of 287.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtracting 0 from 287 leaves us with 287.
Take the next digit (5) from the dividend and append it to 287, then repeat: 2875 / 297

Moving on to step 6:
297 can be fit into 2875 9 times, resulting in a remainder of 202.
Use 9 as the next digit of our solution. 
Result so far: 509.0
Subtracting 2673 from 2875 leaves us with 202.
Include the next digit (0) from the dividend after 202, then repeat: 2020 / 297

Advancing to step 7:
The number 297 fits into 2020 6 times, leaving a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 5096.0
Deduct 1782 from 2020 and we're left with 238.
Bring next digit (2) of the dividend behind the 238 and repeat the process: 2382 / 297

Step 8:
297 goes into 2382 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 50968.0
Subtract 2376 from 2382 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 297, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 50968.0
Subtracting 0 from 60 leaves us 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.

Let's proceed to step 10:
When dividing 600 by 297, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 50968.02
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
When dividing 60 by 297, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 50968.02
Subtracting 0 from 60 leaves us 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.

Advancing to step 12:
600 divided by 297 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 50968.0202
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
297 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 50968.0202
Deduct 0 from 60 and we're left 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 14:
When dividing 600 by 297, we get 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 50968.020202
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 15:
If we divide 60 by 297, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 50968.020202
Deduct 0 from 60 and we're left 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.

Step 16:
The number 297 fits into 600 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 50968.02020202
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 50968.02020202 with a remainder of 6e-09.
