Let's divide 342138 by 10
Our goal is to divide 342138 by 10.

Let's proceed to step 1:
If we divide 3 by 10, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 10

Let's proceed to step 2:
When dividing 34 by 10, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 30 from 34 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 10

Moving on to step 3:
10 goes into 42 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtract 40 from 42 to get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 10

Step 4:
10 can be fit into 21 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 342.0
Subtract 20 from 21 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 10

Let's proceed to step 5:
The number 10 fits into 13 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 3421.0
Subtracting 10 from 13 leaves us with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 10

On to step 6:
If we divide 38 by 10, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 34213.0
If we subtract 30 from 38, 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.

Going ahead to step 7:
When dividing 80 by 10, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 34213.8
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 34213.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 34213.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 34213.8, with a leftover of 0.0.
