35423899 ÷ 17 
The aim is to understand the frequency of 17 in 35423899.

Going ahead to step 1:
If we divide 3 by 17, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 17

Step 2:
If we divide 35 by 17, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 34 away from 35, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 17

Moving on to step 3:
If we divide 14 by 17, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 14 to get 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 17

Going ahead to step 4:
When dividing 142 by 17, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 208.0
Subtract 136 from 142 to get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 17

Step 5:
The number 17 fits into 63 3 times, leaving a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 2083.0
The remainder is 12 after subtracting 51 from 63.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 17

Going ahead to step 6:
17 goes into 128 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 20837.0
The remainder is 9 after subtracting 119 from 128.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 17

On to step 7:
When dividing 99 by 17, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 208375.0
If we take 85 away from 99, we end up with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 17

Moving on to step 8:
17 goes into 149 8 times with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 2083758.0
Subtracting 136 from 149 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 9:
The number 17 fits into 130 7 times, leaving a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 2083758.7
If we subtract 119 from 130, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
110 divided by 17 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 2083758.76
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
80 divided by 17 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 2083758.764
Subtracting 68 from 80 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.

Going ahead to step 12:
17 goes into 120 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 2083758.7647
If we take 119 away from 120, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
17 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2083758.7647
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
The number 17 fits into 100 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 2083758.764705
Subtracting 85 from 100 leaves us 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.

Let's proceed to step 15:
150 divided by 17 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 2083758.7647058
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 16:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 2083758.76470588
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 2083758.76470588 with a remaining 4e-09.
