We look at the division of 659660 by 35 
The aim is to understand the frequency of 35 in 659660.

Advancing to step 1:
35 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 35

Advancing to step 2:
When dividing 65 by 35, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 35 from 65 leaves us with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 35

Moving on to step 3:
35 goes into 309 8 times with a remainder of 29.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 29 after subtracting 280 from 309.
Include the next digit (6) from the dividend after 29, then repeat: 296 / 35

Moving on to step 4:
The number 35 fits into 296 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 188.0
Subtracting 280 from 296 leaves us with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 35

Advancing to step 5:
The number 35 fits into 166 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 1884.0
Subtract 140 from 166 to get 26.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 35

Going ahead to step 6:
If we divide 260 by 35, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 18847.0
Subtract 245 from 260 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 35 fits into 150 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 18847.4
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 35 fits into 100 2 times, leaving a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 18847.42
The remainder is 30 after subtracting 70 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
35 goes into 300 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 18847.428
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
35 goes into 200 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 18847.4285
The remainder is 25 after subtracting 175 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
35 can be fit into 250 7 times, resulting in a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 18847.42857
Subtracting 245 from 250 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
If we divide 50 by 35, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 18847.428571
If we subtract 35 from 50, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 13:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 18847.4285714
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
35 goes into 100 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 18847.42857142
Subtracting 70 from 100 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 18847.42857142 and a remainder of 3e-08.
