19893736 ÷ 297 
The aim is to understand the frequency of 297 in 19893736.

Let's proceed to step 1:
If we divide 1 by 297, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 297

Advancing to step 2:
297 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 297

Step 3:
297 goes into 198 0 times with a remainder of 198.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 198 to get 198.
Take the next digit (9) from the dividend and append it to 198, then repeat: 1989 / 297

On to step 4:
The number 297 fits into 1989 6 times, leaving a remainder of 207.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 1782 from 1989 to get 207.
Grab the next digit (3) from the dividend, add it to 207, then carry on: 2073 / 297

Going ahead to step 5:
2073 divided by 297 is 6 with a remainder of 291.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Deduct 1782 from 2073 and we're left with 291.
Bring next digit (7) of the dividend behind the 291 and repeat the process: 2917 / 297

Going ahead to step 6:
2917 divided by 297 is 9 with a remainder of 244.
Write down 9 as next digit of the result. 
Result so far: 669.0
If we take 2673 away from 2917, we end up with 244.
Take the next digit (3) from the dividend and append it to 244, then repeat: 2443 / 297

On to step 7:
When dividing 2443 by 297, we get 8 with a remainder of 67.
Write down 8 as next digit of the result. 
Result so far: 6698.0
The remainder is 67 after subtracting 2376 from 2443.
Bring next digit (6) of the dividend behind the 67 and repeat the process: 676 / 297

Advancing to step 8:
676 divided by 297 is 2 with a remainder of 82.
The next digit of our result is 2. 
Result so far: 66982.0
Subtracting 594 from 676 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
297 goes into 820 2 times with a remainder of 226.
Record the quotient 2 as the next digit in the result. 
Result so far: 66982.2
Subtracting 594 from 820 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 10:
When dividing 2260 by 297, we get 7 with a remainder of 181.
Put 7 as the next digit of the answer. 
Result so far: 66982.27
The remainder is 181 after subtracting 2079 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 11:
The number 297 fits into 1810 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 66982.276
Subtracting 1782 from 1810 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
280 divided by 297 is 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 66982.276
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 13:
The number 297 fits into 2800 9 times, leaving a remainder of 127.
Put 9 as the next digit of the answer. 
Result so far: 66982.27609
Deduct 2673 from 2800 and we're left with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Let's proceed to step 14:
1270 divided by 297 is 4 with a remainder of 82.
The next digit of our result is 4. 
Result so far: 66982.276094
If we subtract 1188 from 1270, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 15:
297 goes into 820 2 times with a remainder of 226.
The number 2 becomes the next digit in our result. 
Result so far: 66982.2760942
Subtracting 594 from 820 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

On to step 16:
297 can be fit into 2260 7 times, resulting in a remainder of 181.
The number 7 becomes the next digit in our result. 
Result so far: 66982.27609427
If we subtract 2079 from 2260, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

The final result is 66982.27609427 with a remainder of 1.81e-07.
