We look at the division of 42012381 by 483 
Let's see how many times 483 fits into 42012381.

Step 1:
483 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 483

Step 2:
483 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 483

Let's proceed to step 3:
If we divide 420 by 483, we get 0 and a remainder of 420.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 420 to get 420.
Grab the next digit (1) from the dividend, add it to 420, then carry on: 4201 / 483

On to step 4:
When dividing 4201 by 483, we get 8 with a remainder of 337.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 3864 from 4201 to get 337.
Take the next digit (2) from the dividend and append it to 337, then repeat: 3372 / 483

On to step 5:
3372 divided by 483 is 6 with a remainder of 474.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 2898 from 3372 and we're left with 474.
Bring next digit (3) of the dividend behind the 474 and repeat the process: 4743 / 483

Going ahead to step 6:
483 goes into 4743 9 times with a remainder of 396.
Record the quotient 9 as the next digit in the result. 
Result so far: 869.0
If we subtract 4347 from 4743, we get 396.
Fetch the next digit (8) from the dividend, attach it to 396 and continue: 3968 / 483

Going ahead to step 7:
3968 divided by 483 is 8 with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 8698.0
If we subtract 3864 from 3968, we get 104.
Fetch the next digit (1) from the dividend, attach it to 104 and continue: 1041 / 483

Step 8:
483 can be fit into 1041 2 times, resulting in a remainder of 75.
Put 2 as the next digit of the answer. 
Result so far: 86982.0
If we take 966 away from 1041, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 9:
483 goes into 750 1 times with a remainder of 267.
The number 1 becomes the next digit in our result. 
Result so far: 86982.1
Subtracting 483 from 750 leaves us with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Moving on to step 10:
The number 483 fits into 2670 5 times, leaving a remainder of 255.
Put 5 as the next digit of the answer. 
Result so far: 86982.15
The remainder is 255 after subtracting 2415 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 11:
When dividing 2550 by 483, we get 5 with a remainder of 135.
The next digit of our result is 5. 
Result so far: 86982.155
Deduct 2415 from 2550 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

After the division, we end up with 86982.155 and a remainder of 0.0135.
