We're dividing 99367780 by 233 
The aim is to understand the frequency of 233 in 99367780.

Going ahead to step 1:
9 divided by 233 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 233

On to step 2:
The number 233 fits into 99 0 times, leaving a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Take the next digit (3) from the dividend and append it to 99, then repeat: 993 / 233

Advancing to step 3:
If we divide 993 by 233, we get 4 and a remainder of 61.
The next digit of our result is 4. 
Result so far: 4.0
If we take 932 away from 993, we end up with 61.
Include the next digit (6) from the dividend after 61, then repeat: 616 / 233

Going ahead to step 4:
233 can be fit into 616 2 times, resulting in a remainder of 150.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 150 after subtracting 466 from 616.
Grab the next digit (7) from the dividend, add it to 150, then carry on: 1507 / 233

Advancing to step 5:
When dividing 1507 by 233, we get 6 with a remainder of 109.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
Subtracting 1398 from 1507 leaves us with 109.
Take the next digit (7) from the dividend and append it to 109, then repeat: 1097 / 233

Going ahead to step 6:
233 can be fit into 1097 4 times, resulting in a remainder of 165.
Write down 4 as next digit of the result. 
Result so far: 4264.0
The remainder is 165 after subtracting 932 from 1097.
Grab the next digit (8) from the dividend, add it to 165, then carry on: 1658 / 233

Advancing to step 7:
233 can be fit into 1658 7 times, resulting in a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 42647.0
Subtract 1631 from 1658 to get 27.
Bring next digit (0) of the dividend behind the 27 and repeat the process: 270 / 233

Going ahead to step 8:
270 divided by 233 is 1 with a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 426471.0
If we subtract 233 from 270, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 9:
370 divided by 233 is 1 with a remainder of 137.
Put 1 as the next digit of the answer. 
Result so far: 426471.1
The remainder is 137 after subtracting 233 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 10:
233 can be fit into 1370 5 times, resulting in a remainder of 205.
The number 5 becomes the next digit in our result. 
Result so far: 426471.15
If we take 1165 away from 1370, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 11:
233 goes into 2050 8 times with a remainder of 186.
Use 8 as the next digit of our solution. 
Result so far: 426471.158
If we subtract 1864 from 2050, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 12:
1860 divided by 233 is 7 with a remainder of 229.
The next digit of our result is 7. 
Result so far: 426471.1587
If we subtract 1631 from 1860, 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.

On to step 13:
2290 divided by 233 is 9 with a remainder of 193.
The number 9 becomes the next digit in our result. 
Result so far: 426471.15879
If we take 2097 away from 2290, we end up with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 14:
The number 233 fits into 1930 8 times, leaving a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 426471.158798
Deduct 1864 from 1930 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 15:
If we divide 660 by 233, we get 2 and a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 426471.1587982
Subtracting 466 from 660 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 16:
If we divide 1940 by 233, we get 8 and a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 426471.15879828
If we subtract 1864 from 1940, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 426471.15879828, with a leftover of 7.6e-08.
