Let's divide 77317945 by 297
The aim is to understand the frequency of 297 in 77317945.

Going ahead to step 1:
297 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 297

On to step 2:
When dividing 77 by 297, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 297

Advancing to step 3:
297 goes into 773 2 times with a remainder of 179.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 594 away from 773, we end up with 179.
Include the next digit (1) from the dividend after 179, then repeat: 1791 / 297

Moving on to step 4:
The number 297 fits into 1791 6 times, leaving a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 1782 away from 1791, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 297

Moving on to step 5:
The number 297 fits into 97 0 times, leaving a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 260.0
Deduct 0 from 97 and we're left with 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 297

On to step 6:
When dividing 979 by 297, we get 3 with a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 2603.0
The remainder is 88 after subtracting 891 from 979.
Include the next digit (4) from the dividend after 88, then repeat: 884 / 297

Step 7:
When dividing 884 by 297, we get 2 with a remainder of 290.
Use 2 as the next digit of our solution. 
Result so far: 26032.0
If we subtract 594 from 884, we get 290.
Take the next digit (5) from the dividend and append it to 290, then repeat: 2905 / 297

Moving on to step 8:
If we divide 2905 by 297, we get 9 and a remainder of 232.
The next digit of our result is 9. 
Result so far: 260329.0
Deduct 2673 from 2905 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

On to step 9:
2320 divided by 297 is 7 with a remainder of 241.
The next digit of our result is 7. 
Result so far: 260329.7
Subtracting 2079 from 2320 leaves us with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Advancing to step 10:
When dividing 2410 by 297, we get 8 with a remainder of 34.
The next digit of our result is 8. 
Result so far: 260329.78
Subtract 2376 from 2410 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
If we divide 340 by 297, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 260329.781
Deduct 297 from 340 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 12:
When dividing 430 by 297, we get 1 with a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 260329.7811
Subtract 297 from 430 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

The final result is 260329.7811 with a remainder of 0.00133.
