We divide 99500611 by 243
The aim is to understand the frequency of 243 in 99500611.

Moving on to step 1:
9 divided by 243 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 243

Moving on to step 2:
The number 243 fits into 99 0 times, leaving a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 243

Moving on to step 3:
If we divide 995 by 243, we get 4 and a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 972 from 995 and we're left with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 243

Going ahead to step 4:
230 divided by 243 is 0 with a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
If we subtract 0 from 230, we get 230.
Bring next digit (0) of the dividend behind the 230 and repeat the process: 2300 / 243

Step 5:
243 goes into 2300 9 times with a remainder of 113.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
The remainder is 113 after subtracting 2187 from 2300.
Bring next digit (6) of the dividend behind the 113 and repeat the process: 1136 / 243

Going ahead to step 6:
1136 divided by 243 is 4 with a remainder of 164.
The next digit of our result is 4. 
Result so far: 4094.0
Subtracting 972 from 1136 leaves us with 164.
Grab the next digit (1) from the dividend, add it to 164, then carry on: 1641 / 243

Going ahead to step 7:
The number 243 fits into 1641 6 times, leaving a remainder of 183.
The number 6 becomes the next digit in our result. 
Result so far: 40946.0
Subtract 1458 from 1641 to get 183.
Grab the next digit (1) from the dividend, add it to 183, then carry on: 1831 / 243

Advancing to step 8:
243 can be fit into 1831 7 times, resulting in a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 409467.0
Subtract 1701 from 1831 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 9:
If we divide 1300 by 243, we get 5 and a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 409467.5
Subtract 1215 from 1300 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 10:
243 can be fit into 850 3 times, resulting in a remainder of 121.
Put 3 as the next digit of the answer. 
Result so far: 409467.53
Subtracting 729 from 850 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 11:
243 goes into 1210 4 times with a remainder of 238.
Record the quotient 4 as the next digit in the result. 
Result so far: 409467.534
Subtract 972 from 1210 to get 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 12:
243 can be fit into 2380 9 times, resulting in a remainder of 193.
The next digit of our result is 9. 
Result so far: 409467.5349
If we subtract 2187 from 2380, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 13:
If we divide 1930 by 243, we get 7 and a remainder of 229.
Put 7 as the next digit of the answer. 
Result so far: 409467.53497
Deduct 1701 from 1930 and we're left 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.

Going ahead to step 14:
2290 divided by 243 is 9 with a remainder of 103.
The next digit of our result is 9. 
Result so far: 409467.534979
The remainder is 103 after subtracting 2187 from 2290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 15:
243 goes into 1030 4 times with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 409467.5349794
Subtracting 972 from 1030 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 16:
If we divide 580 by 243, we get 2 and a remainder of 94.
The next digit of our result is 2. 
Result so far: 409467.53497942
If we take 486 away from 580, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

In conclusion, the division gives 409467.53497942 with a balance of 9.4e-08.
