42007 ÷ 3 
We want to divide 42007 by 3.

Going ahead to step 1:
4 divided by 3 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 4 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Going ahead to step 2:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 12 from 12 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Moving on to step 3:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Let's proceed to step 4:
3 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1400.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 3

On to step 5:
If we divide 7 by 3, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 14002.0
The remainder is 1 after subtracting 6 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 14002.3
Subtract 9 from 10 to 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.

Let's proceed to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 14002.33
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 14002.33 with a remaining 0.001.
