Let's divide 423709 by 34
We want to figure out the number of times 423709 can be divided by 34.

On to step 1:
When dividing 4 by 34, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 34

On to step 2:
42 divided by 34 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 8 after subtracting 34 from 42.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 34

Step 3:
When dividing 83 by 34, we get 2 with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 68 away from 83, we end up with 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 34

Step 4:
157 divided by 34 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 124.0
If we take 136 away from 157, we end up with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 34

Going ahead to step 5:
34 goes into 210 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 1246.0
If we take 204 away from 210, we end up with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 34

Let's proceed to step 6:
69 divided by 34 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 12462.0
If we subtract 68 from 69, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 34 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 12462.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 34, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 12462.02
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.

Going ahead to step 9:
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: 12462.029
Subtract 306 from 320 to get 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 10:
140 divided by 34 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 12462.0294
If we subtract 136 from 140, we 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.

Advancing to step 11:
40 divided by 34 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 12462.02941
Subtract 34 from 40 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
When dividing 60 by 34, we get 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 12462.029411
Deduct 34 from 60 and we're left 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.

The final result is 12462.029411 with a remainder of 2.6e-06.
