Let's divide 421007 by 35
The aim is to understand the frequency of 35 in 421007.

On to step 1:
The number 35 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 35

Moving on to step 2:
If we divide 42 by 35, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 35 away from 42, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 35

Moving on to step 3:
The number 35 fits into 71 2 times, leaving a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 70 from 71, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 35

Let's proceed to step 4:
10 divided by 35 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we subtract 0 from 10, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 35

Advancing to step 5:
35 goes into 100 2 times with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 1202.0
If we take 70 away from 100, we end up with 30.
Include the next digit (7) from the dividend after 30, then repeat: 307 / 35

On to step 6:
35 goes into 307 8 times with a remainder of 27.
Use 8 as the next digit of our solution. 
Result so far: 12028.0
If we take 280 away from 307, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
The number 35 fits into 270 7 times, leaving a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 12028.7
If we subtract 245 from 270, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
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: 12028.77
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.

The final outcome is 12028.77, with a leftover of 0.005.
