250231 divided by 42 
Our goal is to divide 250231 by 42.

Advancing to step 1:
2 divided by 42 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 42

On to step 2:
42 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (0) from the dividend and append it to 25, then repeat: 250 / 42

Advancing to step 3:
42 can be fit into 250 5 times, resulting in a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 210 from 250 and we're left with 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 42

Moving on to step 4:
42 can be fit into 402 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 59.0
Subtracting 378 from 402 leaves us with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 42

On to step 5:
When dividing 243 by 42, we get 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 595.0
Subtract 210 from 243 to get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 42

Going ahead to step 6:
42 can be fit into 331 7 times, resulting in a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 5957.0
If we take 294 away from 331, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
If we divide 370 by 42, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 5957.8
Subtracting 336 from 370 leaves us 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.

Moving on to step 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 5957.88
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 5957.88, and the remainder is 0.004.
