We're dividing 85999422 by 243 
The aim is to understand the frequency of 243 in 85999422.

Going ahead to step 1:
8 divided by 243 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 243

On to step 2:
The number 243 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Append the next digit (9) from the dividend to 85 and continue with: 859 / 243

On to step 3:
When dividing 859 by 243, we get 3 with a remainder of 130.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 729 from 859 and we're left with 130.
Take the next digit (9) from the dividend and append it to 130, then repeat: 1309 / 243

Step 4:
When dividing 1309 by 243, we get 5 with a remainder of 94.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtract 1215 from 1309 to get 94.
Append the next digit (9) from the dividend to 94 and continue with: 949 / 243

Let's proceed to step 5:
When dividing 949 by 243, we get 3 with a remainder of 220.
Write down 3 as next digit of the result. 
Result so far: 353.0
If we take 729 away from 949, we end up with 220.
Fetch the next digit (4) from the dividend, attach it to 220 and continue: 2204 / 243

On to step 6:
243 can be fit into 2204 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 3539.0
If we take 2187 away from 2204, we end up with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 243

Step 7:
172 divided by 243 is 0 with a remainder of 172.
The next digit of our result is 0. 
Result so far: 35390.0
If we subtract 0 from 172, we get 172.
Take the next digit (2) from the dividend and append it to 172, then repeat: 1722 / 243

On to step 8:
1722 divided by 243 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 353907.0
Subtract 1701 from 1722 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 9:
210 divided by 243 is 0 with a remainder of 210.
The number 0 becomes the next digit in our result. 
Result so far: 353907.0
Subtracting 0 from 210 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Moving on to step 10:
When dividing 2100 by 243, we get 8 with a remainder of 156.
The next digit of our result is 8. 
Result so far: 353907.08
If we take 1944 away from 2100, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 11:
243 can be fit into 1560 6 times, resulting in a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 353907.086
The remainder is 102 after subtracting 1458 from 1560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 12:
1020 divided by 243 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 353907.0864
Deduct 972 from 1020 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
If we divide 480 by 243, we get 1 and a remainder of 237.
The next digit of our result is 1. 
Result so far: 353907.08641
If we subtract 243 from 480, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Advancing to step 14:
The number 243 fits into 2370 9 times, leaving a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 353907.086419
Subtract 2187 from 2370 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Step 15:
The number 243 fits into 1830 7 times, leaving a remainder of 129.
Record the quotient 7 as the next digit in the result. 
Result so far: 353907.0864197
Subtracting 1701 from 1830 leaves us with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

On to step 16:
243 can be fit into 1290 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 353907.08641975
Subtracting 1215 from 1290 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

In conclusion, the division gives 353907.08641975 with a balance of 7.5e-08.
