Let's divide 426216 by 99
The aim is to understand the frequency of 99 in 426216.

Going ahead to step 1:
If we divide 4 by 99, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 99

Advancing to step 2:
99 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 99

Let's proceed to step 3:
426 divided by 99 is 4 with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 396 from 426 and we're left with 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 99

Let's proceed to step 4:
When dividing 302 by 99, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 297 from 302 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 99

Moving on to step 5:
If we divide 51 by 99, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 430.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (6) from the dividend, attach it to 51 and continue: 516 / 99

Going ahead to step 6:
99 goes into 516 5 times with a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 4305.0
Deduct 495 from 516 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
210 divided by 99 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 4305.2
Subtracting 198 from 210 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
If we divide 120 by 99, we get 1 and a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 4305.21
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
If we divide 210 by 99, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 4305.212
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
If we divide 120 by 99, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 4305.2121
Subtracting 99 from 120 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
99 can be fit into 210 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 4305.21212
Subtracting 198 from 210 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
99 can be fit into 120 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 4305.212121
Subtracting 99 from 120 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 13:
210 divided by 99 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 4305.2121212
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
99 can be fit into 120 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 4305.21212121
Subtracting 99 from 120 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 4305.21212121, with a leftover of 2.1e-08.
