Let's divide 404139 by 34
The aim is to understand the frequency of 34 in 404139.

Advancing to step 1:
4 divided by 34 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 34

Moving on to step 2:
If we divide 40 by 34, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 34 from 40 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 34

Step 3:
If we divide 64 by 34, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 34 from 64 and we're left with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 34

Let's proceed to step 4:
If we divide 301 by 34, we get 8 and a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtracting 272 from 301 leaves us with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 34

Step 5:
When dividing 293 by 34, we get 8 with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 1188.0
Deduct 272 from 293 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 34

Moving on to step 6:
219 divided by 34 is 6 with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 11886.0
If we take 204 away from 219, we end up 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.

Going ahead to step 7:
If we divide 150 by 34, we get 4 and a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 11886.4
If we take 136 away from 150, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
The number 34 fits into 140 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 11886.44
Subtracting 136 from 140 leaves us 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.

The final result is 11886.44 with a remainder of 0.004.
