We're dividing 621728 by 35 
The aim is to understand the frequency of 35 in 621728.

Advancing to step 1:
If we divide 6 by 35, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 35

Moving on to step 2:
The number 35 fits into 62 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 35 from 62 leaves us with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 35

Going ahead to step 3:
If we divide 271 by 35, we get 7 and a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 245 from 271 and we're left with 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 35

Going ahead to step 4:
When dividing 267 by 35, we get 7 with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 177.0
The remainder is 22 after subtracting 245 from 267.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 35

Advancing to step 5:
If we divide 222 by 35, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 1776.0
Subtracting 210 from 222 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 35

Let's proceed to step 6:
35 can be fit into 128 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 17763.0
Subtracting 105 from 128 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
When dividing 230 by 35, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 17763.6
The remainder is 20 after subtracting 210 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 17763.65
Deduct 175 from 200 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
If we divide 250 by 35, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 17763.657
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 10:
35 goes into 50 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 17763.6571
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.

Step 11:
If we divide 150 by 35, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 17763.65714
The remainder is 10 after subtracting 140 from 150.
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 12:
The number 35 fits into 100 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 17763.657142
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.

Step 13:
The number 35 fits into 300 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 17763.6571428
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.

On to step 14:
35 can be fit into 200 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 17763.65714285
Subtracting 175 from 200 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 17763.65714285 and a remainder of 2.5e-08.
