We look at the division of 97681909 by 369 
The aim is to understand the frequency of 369 in 97681909.

Step 1:
369 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 369

Moving on to step 2:
If we divide 97 by 369, we get 0 and a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Bring next digit (6) of the dividend behind the 97 and repeat the process: 976 / 369

Advancing to step 3:
976 divided by 369 is 2 with a remainder of 238.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 738 from 976 leaves us with 238.
Fetch the next digit (8) from the dividend, attach it to 238 and continue: 2388 / 369

Advancing to step 4:
2388 divided by 369 is 6 with a remainder of 174.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 2214 from 2388 leaves us with 174.
Fetch the next digit (1) from the dividend, attach it to 174 and continue: 1741 / 369

Step 5:
1741 divided by 369 is 4 with a remainder of 265.
The number 4 becomes the next digit in our result. 
Result so far: 264.0
Deduct 1476 from 1741 and we're left with 265.
Take the next digit (9) from the dividend and append it to 265, then repeat: 2659 / 369

On to step 6:
The number 369 fits into 2659 7 times, leaving a remainder of 76.
The number 7 becomes the next digit in our result. 
Result so far: 2647.0
Subtracting 2583 from 2659 leaves us with 76.
Append the next digit (0) from the dividend to 76 and continue with: 760 / 369

Advancing to step 7:
760 divided by 369 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 26472.0
If we take 738 away from 760, we end up with 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 369

On to step 8:
369 can be fit into 229 0 times, resulting in a remainder of 229.
Write down 0 as next digit of the result. 
Result so far: 264720.0
If we subtract 0 from 229, we get 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 9:
When dividing 2290 by 369, we get 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 264720.6
The remainder is 76 after subtracting 2214 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
If we divide 760 by 369, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 264720.62
Deduct 738 from 760 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
When dividing 220 by 369, we get 0 with a remainder of 220.
The next digit of our result is 0. 
Result so far: 264720.62
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 12:
If we divide 2200 by 369, we get 5 and a remainder of 355.
The next digit of our result is 5. 
Result so far: 264720.6205
If we subtract 1845 from 2200, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 13:
If we divide 3550 by 369, we get 9 and a remainder of 229.
Write down 9 as next digit of the result. 
Result so far: 264720.62059
Subtracting 3321 from 3550 leaves us with 229.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

On to step 14:
369 can be fit into 2290 6 times, resulting in a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 264720.620596
The remainder is 76 after subtracting 2214 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
760 divided by 369 is 2 with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 264720.6205962
Subtracting 738 from 760 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 16:
369 can be fit into 220 0 times, resulting in a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 264720.6205962
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

In conclusion, the division gives 264720.6205962 with a balance of 2.2e-07.
