We look at the division of 878553 by 34 
The aim is to understand the frequency of 34 in 878553.

Let's proceed to step 1:
34 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 34

Advancing to step 2:
When dividing 87 by 34, we get 2 with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 68 from 87 to get 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 34

Moving on to step 3:
The number 34 fits into 198 5 times, leaving a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 170 from 198 to get 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 34

Moving on to step 4:
34 can be fit into 285 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
Subtracting 272 from 285 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 34

On to step 5:
When dividing 135 by 34, we get 3 with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 2583.0
Deduct 102 from 135 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 34

On to step 6:
When dividing 333 by 34, we get 9 with a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 25839.0
If we take 306 away from 333, 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 34 fits into 270 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 25839.7
The remainder is 32 after subtracting 238 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
When dividing 320 by 34, we get 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 25839.79
Subtracting 306 from 320 leaves us 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.

Advancing to step 9:
140 divided by 34 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 25839.794
Subtract 136 from 140 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
34 goes into 40 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 25839.7941
The remainder is 6 after subtracting 34 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
When dividing 60 by 34, we get 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 25839.79411
Subtracting 34 from 60 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 25839.79411 with a remaining 2.6e-05.
