839809 divided by 35 
The aim is to understand the frequency of 35 in 839809.

On to step 1:
8 divided by 35 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 35

Let's proceed to step 2:
If we divide 83 by 35, we get 2 and a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 70 from 83, we get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 35

Advancing to step 3:
139 divided by 35 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 23.0
The remainder is 34 after subtracting 105 from 139.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 35

On to step 4:
When dividing 348 by 35, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
If we subtract 315 from 348, we get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 35

Moving on to step 5:
35 goes into 330 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 2399.0
Subtract 315 from 330 to get 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 35

Going ahead to step 6:
The number 35 fits into 159 4 times, leaving a remainder of 19.
The next digit of our result is 4. 
Result so far: 23994.0
Subtract 140 from 159 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 35, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 23994.5
If we take 175 away from 190, 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.

Moving on to step 8:
The number 35 fits into 150 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 23994.54
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.

Step 9:
35 can be fit into 100 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 23994.542
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 10:
When dividing 300 by 35, we get 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 23994.5428
The remainder is 20 after subtracting 280 from 300.
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 11:
When dividing 200 by 35, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 23994.54285
If we subtract 175 from 200, 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.

Moving on to step 12:
The number 35 fits into 250 7 times, leaving a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 23994.542857
Subtract 245 from 250 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
When dividing 50 by 35, we get 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 23994.5428571
Subtract 35 from 50 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
35 can be fit into 150 4 times, resulting in a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 23994.54285714
If we subtract 140 from 150, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 23994.54285714 with a balance of 1e-08.
