The aim is to understand the frequency of 99 in 42845639.

On to step 1:
The number 99 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 99

Moving on to step 2:
42 divided by 99 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 99

On to step 3:
99 can be fit into 428 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 32 after subtracting 396 from 428.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 99

Advancing to step 4:
99 goes into 324 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 297 from 324 to get 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 99

Moving on to step 5:
99 can be fit into 275 2 times, resulting in a remainder of 77.
Put 2 as the next digit of the answer. 
Result so far: 432.0
Deduct 198 from 275 and we're left with 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 99

Advancing to step 6:
When dividing 776 by 99, we get 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 4327.0
Subtracting 693 from 776 leaves us with 83.
Grab the next digit (3) from the dividend, add it to 83, then carry on: 833 / 99

Moving on to step 7:
99 can be fit into 833 8 times, resulting in a remainder of 41.
Write down 8 as next digit of the result. 
Result so far: 43278.0
Deduct 792 from 833 and we're left with 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 99

Moving on to step 8:
The number 99 fits into 419 4 times, leaving a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 432784.0
Deduct 396 from 419 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
The number 99 fits into 230 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 432784.2
If we subtract 198 from 230, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
320 divided by 99 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 432784.23
If we take 297 away from 320, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
230 divided by 99 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 432784.232
The remainder is 32 after subtracting 198 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
99 can be fit into 320 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 432784.2323
The remainder is 23 after subtracting 297 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 13:
When dividing 230 by 99, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 432784.23232
Subtract 198 from 230 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
99 goes into 320 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 432784.232323
Subtracting 297 from 320 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 15:
99 goes into 230 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 432784.2323232
If we take 198 away from 230, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 16:
99 goes into 320 3 times with a remainder of 23.
The next digit of our result is 3. 
Result so far: 432784.23232323
Deduct 297 from 320 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 432784.23232323 with a balance of 2.3e-08.
