We're dividing 669521 by 34 
The aim is to understand the frequency of 34 in 669521.

On to step 1:
34 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 34

On to step 2:
34 goes into 66 1 times with a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 34 from 66, we get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 34

Moving on to step 3:
34 can be fit into 329 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 23 after subtracting 306 from 329.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 34

Going ahead to step 4:
235 divided by 34 is 6 with a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 196.0
The remainder is 31 after subtracting 204 from 235.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 34

Let's proceed to step 5:
The number 34 fits into 312 9 times, leaving a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 1969.0
Subtract 306 from 312 to get 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 34

Advancing to step 6:
34 can be fit into 61 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 19691.0
If we subtract 34 from 61, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 34 fits into 270 7 times, leaving a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 19691.7
If we subtract 238 from 270, we get 32.
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:
34 can be fit into 320 9 times, resulting in a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 19691.79
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.

Step 9:
The number 34 fits into 140 4 times, leaving a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 19691.794
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.

Advancing to step 10:
34 can be fit into 40 1 times, resulting in a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 19691.7941
Subtracting 34 from 40 leaves us with 6.
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:
The number 34 fits into 60 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 19691.79411
If we subtract 34 from 60, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 19691.79411 and a remainder of 2.6e-05.
