We look at the division of 420324 by 34 
We want to divide 420324 by 34.

Step 1:
When dividing 4 by 34, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 34

Let's proceed to step 2:
When dividing 42 by 34, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 34 from 42, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 34

On to step 3:
If we divide 80 by 34, we get 2 and a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 68 away from 80, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 34

Advancing to step 4:
If we divide 123 by 34, we get 3 and a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
If we subtract 102 from 123, we get 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 34

On to step 5:
When dividing 212 by 34, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1236.0
If we take 204 away from 212, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 34

Moving on to step 6:
34 goes into 84 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 12362.0
Subtract 68 from 84 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
When dividing 160 by 34, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 12362.4
If we take 136 away from 160, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
When dividing 240 by 34, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 12362.47
Subtract 238 from 240 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.

Step 9:
If we divide 20 by 34, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12362.47
Subtracting 0 from 20 leaves us 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.

On to step 10:
The number 34 fits into 200 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 12362.4705
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 34, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 12362.47058
If we take 272 away from 300, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
280 divided by 34 is 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 12362.470588
Deduct 272 from 280 and we're left 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.

In conclusion, the division gives 12362.470588 with a balance of 8e-07.
