127407 divided by 42 
We want to divide 127407 by 42.

Step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 42

Going ahead to step 2:
If we divide 12 by 42, we get 0 and a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 42

On to step 3:
42 goes into 127 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 126 from 127 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 42

On to step 4:
42 goes into 14 0 times with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 30.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 42

Let's proceed to step 5:
When dividing 140 by 42, we get 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 303.0
Subtracting 126 from 140 leaves us with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 42

Let's proceed to step 6:
The number 42 fits into 147 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 3033.0
The remainder is 21 after subtracting 126 from 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
When dividing 210 by 42, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3033.5
Subtract 210 from 210 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 42, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3033.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
If we divide 0 by 42, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3033.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 3033.5, and the remainder is 0.0.
