Let's divide 142838 by 34
Our goal is to divide 142838 by 34.

Going ahead to step 1:
If we divide 1 by 34, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 34

Going ahead to step 2:
14 divided by 34 is 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 34

Going ahead to step 3:
The number 34 fits into 142 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 6 after subtracting 136 from 142.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 34

Advancing to step 4:
34 goes into 68 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 68 away from 68, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 34

Advancing to step 5:
If we divide 3 by 34, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 420.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 34

Going ahead to step 6:
34 can be fit into 38 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 4201.0
Subtracting 34 from 38 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.

Moving on to step 7:
When dividing 40 by 34, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 4201.1
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.

On to step 8:
When dividing 60 by 34, we get 1 with a remainder of 26.
The next digit of our result is 1. 
Result so far: 4201.11
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 4201.11 with a remainder of 0.026.
