We're dividing 624439 by 35 
The aim is to understand the frequency of 35 in 624439.

Advancing to step 1:
The number 35 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 35

On to step 2:
62 divided by 35 is 1 with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 35 from 62, we get 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 35

Going ahead to step 3:
274 divided by 35 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 245 from 274 to get 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 35

Advancing to step 4:
294 divided by 35 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we subtract 280 from 294, we get 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 35

Let's proceed to step 5:
35 can be fit into 143 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1784.0
If we take 140 away from 143, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 35

Advancing to step 6:
35 can be fit into 39 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 17841.0
Deduct 35 from 39 and we're left 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.

Step 7:
40 divided by 35 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 17841.1
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.

Advancing to step 8:
The number 35 fits into 50 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 17841.11
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 17841.11, and the remainder is 0.015.
