423209 ÷ 34 
The aim is to understand the frequency of 34 in 423209.

On to step 1:
34 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 34

Advancing to step 2:
34 goes into 42 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 8 after subtracting 34 from 42.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 34

On to step 3:
The number 34 fits into 83 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 15 after subtracting 68 from 83.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 34

Advancing to step 4:
If we divide 152 by 34, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
If we subtract 136 from 152, we get 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 34

Moving on to step 5:
34 can be fit into 160 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 1244.0
If we take 136 away from 160, we end up with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 34

Step 6:
If we divide 249 by 34, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 12447.0
If we subtract 238 from 249, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
34 goes into 110 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 12447.3
If we subtract 102 from 110, we 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.

On to step 8:
If we divide 80 by 34, we get 2 and a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12447.32
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
34 can be fit into 120 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 12447.323
If we take 102 away from 120, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
If we divide 180 by 34, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 12447.3235
Subtract 170 from 180 to 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.

Let's proceed to step 11:
When dividing 100 by 34, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 12447.32352
Deduct 68 from 100 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
When dividing 320 by 34, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 12447.323529
Deduct 306 from 320 and we're left 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.

Going ahead to step 13:
34 can be fit into 140 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 12447.3235294
If we take 136 away from 140, we end up 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.

Step 14:
40 divided by 34 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 12447.32352941
Deduct 34 from 40 and we're left 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.

The final outcome is 12447.32352941, with a leftover of 6e-09.
