We divide 12883 by 42
Our goal is to divide 12883 by 42.

Advancing to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 42

Let's proceed to step 2:
42 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 42

On to step 3:
42 goes into 128 3 times with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 126 from 128 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 42

Advancing to step 4:
When dividing 28 by 42, we get 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 28, we get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 42

Step 5:
The number 42 fits into 283 6 times, leaving a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
Deduct 252 from 283 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 6:
The number 42 fits into 310 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 306.7
Deduct 294 from 310 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
When dividing 160 by 42, we get 3 with a remainder of 34.
Put 3 as the next digit of the answer. 
Result so far: 306.73
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
42 can be fit into 340 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 306.738
Subtracting 336 from 340 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.

On to step 9:
The number 42 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 306.738
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
42 goes into 400 9 times with a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 306.73809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
42 goes into 220 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 306.738095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
The number 42 fits into 100 2 times, leaving a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 306.7380952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
When dividing 160 by 42, we get 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 306.73809523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 306.73809523, with a leftover of 3.4e-08.
