We look at the division of 573451 by 34 
The aim is to understand the frequency of 34 in 573451.

Moving on to step 1:
If we divide 5 by 34, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 34

Advancing to step 2:
The number 34 fits into 57 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 34 from 57 to get 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 34

On to step 3:
The number 34 fits into 233 6 times, leaving a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 204 from 233 to get 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 34

On to step 4:
If we divide 294 by 34, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 168.0
Subtract 272 from 294 to get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 34

Going ahead to step 5:
34 can be fit into 225 6 times, resulting in a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 1686.0
The remainder is 21 after subtracting 204 from 225.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 34

Let's proceed to step 6:
34 goes into 211 6 times with a remainder of 7.
The next digit of our result is 6. 
Result so far: 16866.0
Subtract 204 from 211 to get 7.
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 can be fit into 70 2 times, resulting in a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 16866.2
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
If we divide 20 by 34, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 16866.2
Deduct 0 from 20 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.

Step 9:
The number 34 fits into 200 5 times, leaving a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 16866.205
Deduct 170 from 200 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.

Step 10:
The number 34 fits into 300 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 16866.2058
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:
34 goes into 280 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 16866.20588
Subtracting 272 from 280 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 16866.20588 with a remaining 8e-06.
