998799 ÷ 35 
The aim is to understand the frequency of 35 in 998799.

Step 1:
35 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 35

Step 2:
When dividing 99 by 35, we get 2 with a remainder of 29.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 70 from 99 leaves us with 29.
Take the next digit (8) from the dividend and append it to 29, then repeat: 298 / 35

Going ahead to step 3:
35 can be fit into 298 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 280 from 298, we get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 35

Advancing to step 4:
The number 35 fits into 187 5 times, leaving a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 285.0
If we take 175 away from 187, we end up with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 35

Advancing to step 5:
The number 35 fits into 129 3 times, leaving a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 2853.0
If we take 105 away from 129, we end up with 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 35

On to step 6:
The number 35 fits into 249 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 28537.0
If we take 245 away from 249, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 35 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 28537.1
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
The number 35 fits into 50 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 28537.11
Deduct 35 from 50 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 28537.11, and the remainder is 0.015.
