Let's divide 266863 by 42
We want to divide 266863 by 42.

Advancing to step 1:
The number 42 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 42

Step 2:
When dividing 26 by 42, we get 0 with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 42

Going ahead to step 3:
If we divide 266 by 42, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 252 from 266 leaves us with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 42

Going ahead to step 4:
When dividing 148 by 42, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtracting 126 from 148 leaves us with 22.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 42

Moving on to step 5:
The number 42 fits into 226 5 times, leaving a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 635.0
The remainder is 16 after subtracting 210 from 226.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 42

On to step 6:
42 goes into 163 3 times with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 6353.0
If we subtract 126 from 163, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
The number 42 fits into 370 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 6353.8
If we take 336 away from 370, we end up 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.

Let's proceed to step 8:
When dividing 340 by 42, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 6353.88
Deduct 336 from 340 and we're left 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.

After the division, we end up with 6353.88 and a remainder of 0.004.
