We're dividing 35406 by 99 
The aim is to understand the frequency of 99 in 35406.

Advancing to step 1:
The number 99 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 99

On to step 2:
99 can be fit into 35 0 times, resulting in a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 99

Step 3:
99 can be fit into 354 3 times, resulting in a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 57 after subtracting 297 from 354.
Append the next digit (0) from the dividend to 57 and continue with: 570 / 99

Advancing to step 4:
99 can be fit into 570 5 times, resulting in a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 75 after subtracting 495 from 570.
Take the next digit (6) from the dividend and append it to 75, then repeat: 756 / 99

Moving on to step 5:
99 goes into 756 7 times with a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 357.0
Subtract 693 from 756 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 6:
The number 99 fits into 630 6 times, leaving a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 357.6
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
If we divide 360 by 99, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 357.63
If we take 297 away from 360, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
If we divide 630 by 99, we get 6 and a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 357.636
Subtracting 594 from 630 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
When dividing 360 by 99, we get 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 357.6363
Deduct 297 from 360 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 10:
630 divided by 99 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 357.63636
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
If we divide 360 by 99, we get 3 and a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 357.636363
If we take 297 away from 360, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 12:
630 divided by 99 is 6 with a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 357.6363636
The remainder is 36 after subtracting 594 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
If we divide 360 by 99, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 357.63636363
If we subtract 297 from 360, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The quotient of the division is 357.63636363, and the remainder is 6.3e-08.
