We look at the division of 249390 by 99 
We want to figure out the number of times 249390 can be divided by 99.

On to step 1:
2 divided by 99 is 0 with 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 (4) from the dividend, attach it to 2 and continue: 24 / 99

Step 2:
The number 99 fits into 24 0 times, leaving a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 99

On to step 3:
249 divided by 99 is 2 with a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 198 from 249, we get 51.
Include the next digit (3) from the dividend after 51, then repeat: 513 / 99

Let's proceed to step 4:
99 goes into 513 5 times with a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 495 from 513 and we're left with 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 99

Step 5:
When dividing 189 by 99, we get 1 with a remainder of 90.
The next digit of our result is 1. 
Result so far: 251.0
Subtracting 99 from 189 leaves us with 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 99

Advancing to step 6:
99 goes into 900 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 2519.0
If we subtract 891 from 900, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
When dividing 90 by 99, we get 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 2519.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 8:
When dividing 900 by 99, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 2519.09
Deduct 891 from 900 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
99 goes into 90 0 times with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 2519.09
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 10:
When dividing 900 by 99, we get 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 2519.0909
If we subtract 891 from 900, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 11:
99 goes into 90 0 times with a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 2519.0909
Deduct 0 from 90 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
When dividing 900 by 99, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 2519.090909
If we take 891 away from 900, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 13:
When dividing 90 by 99, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 2519.090909
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 14:
99 can be fit into 900 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 2519.09090909
Deduct 891 from 900 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 2519.09090909, and the remainder is 9e-09.
