248510 ÷ 90 
Let's see how many times 90 fits into 248510.

Going ahead to step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 90

Moving on to step 2:
If we divide 24 by 90, we get 0 and a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 24, we get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 90

Going ahead to step 3:
When dividing 248 by 90, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 180 from 248 and we're left with 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 90

Let's proceed to step 4:
The number 90 fits into 685 7 times, leaving a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 630 from 685 and we're left with 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 90

Advancing to step 5:
90 goes into 551 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 276.0
Deduct 540 from 551 and we're left with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 90

Advancing to step 6:
90 goes into 110 1 times with a remainder of 20.
The next digit of our result is 1. 
Result so far: 2761.0
The remainder is 20 after subtracting 90 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
200 divided by 90 is 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 2761.2
Deduct 180 from 200 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 90 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2761.22
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 2761.22 and a remainder of 0.02.
