We look at the division of 903863 by 34 
The aim is to understand the frequency of 34 in 903863.

On to step 1:
The number 34 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 34

Going ahead to step 2:
If we divide 90 by 34, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 68 from 90, we get 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 34

Advancing to step 3:
The number 34 fits into 223 6 times, leaving a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
The remainder is 19 after subtracting 204 from 223.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 34

On to step 4:
When dividing 198 by 34, we get 5 with a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 265.0
If we take 170 away from 198, we end up with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 34

Step 5:
34 goes into 286 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 2658.0
The remainder is 14 after subtracting 272 from 286.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 34

Advancing to step 6:
When dividing 143 by 34, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 26584.0
The remainder is 7 after subtracting 136 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
34 goes into 70 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 26584.2
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 34 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 26584.2
If we take 0 away from 20, we end up 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.

Advancing to step 9:
When dividing 200 by 34, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 26584.205
Subtracting 170 from 200 leaves us 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.

Step 10:
If we divide 300 by 34, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 26584.2058
The remainder is 28 after subtracting 272 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
The number 34 fits into 280 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 26584.20588
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 26584.20588 and a remainder of 8e-06.
