242458 divided by 45 
We want to divide 242458 by 45.

Advancing to step 1:
45 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 45

Moving on to step 2:
The number 45 fits into 24 0 times, leaving a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 45

On to step 3:
45 can be fit into 242 5 times, resulting in a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 225 from 242 to get 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 45

Step 4:
The number 45 fits into 174 3 times, leaving a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Deduct 135 from 174 and we're left with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 45

Going ahead to step 5:
395 divided by 45 is 8 with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 538.0
The remainder is 35 after subtracting 360 from 395.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 45

Going ahead to step 6:
If we divide 358 by 45, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 5387.0
Subtracting 315 from 358 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
If we divide 430 by 45, we get 9 and a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 5387.9
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
250 divided by 45 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5387.95
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
45 goes into 250 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5387.955
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 5387.955, and the remainder is 0.0025.
