We look at the division of 439946 by 35 
The aim is to understand the frequency of 35 in 439946.

Let's proceed to step 1:
35 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 35

Advancing to step 2:
35 goes into 43 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 35 from 43 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 35

On to step 3:
35 can be fit into 89 2 times, resulting in a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 70 from 89 and we're left with 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 35

Advancing to step 4:
The number 35 fits into 199 5 times, leaving a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we take 175 away from 199, we end up with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 35

Advancing to step 5:
35 can be fit into 244 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 1256.0
The remainder is 34 after subtracting 210 from 244.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 35

Moving on to step 6:
If we divide 346 by 35, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 12569.0
Deduct 315 from 346 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
35 goes into 310 8 times with a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 12569.8
Deduct 280 from 310 and we're left 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.

On to step 8:
35 can be fit into 300 8 times, resulting in a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 12569.88
Deduct 280 from 300 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 12569.88, with a leftover of 0.02.
