Let's divide 12007142 by 586
Our goal is to divide 12007142 by 586.

Moving on to step 1:
1 divided by 586 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 586

On to step 2:
When dividing 12 by 586, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 586

Step 3:
The number 586 fits into 120 0 times, leaving a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 120, we end up with 120.
Bring next digit (0) of the dividend behind the 120 and repeat the process: 1200 / 586

Going ahead to step 4:
The number 586 fits into 1200 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1172 from 1200, we get 28.
Append the next digit (7) from the dividend to 28 and continue with: 287 / 586

Moving on to step 5:
586 can be fit into 287 0 times, resulting in a remainder of 287.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 287 leaves us with 287.
Grab the next digit (1) from the dividend, add it to 287, then carry on: 2871 / 586

Going ahead to step 6:
586 goes into 2871 4 times with a remainder of 527.
Write down 4 as next digit of the result. 
Result so far: 204.0
If we subtract 2344 from 2871, we get 527.
Include the next digit (4) from the dividend after 527, then repeat: 5274 / 586

Step 7:
The number 586 fits into 5274 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2049.0
Subtracting 5274 from 5274 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 586

Step 8:
If we divide 2 by 586, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 20490.0
Subtracting 0 from 2 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
586 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 20490.0
Deduct 0 from 20 and we're left 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.

Moving on to step 10:
200 divided by 586 is 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 20490.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 20490.0 with a balance of 0.2.
