251513 ÷ 99 
Let's see how many times 99 fits into 251513.

On to step 1:
The number 99 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 99

Step 2:
25 divided by 99 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 99

Advancing to step 3:
99 goes into 251 2 times with a remainder of 53.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 198 from 251 and we're left with 53.
Grab the next digit (5) from the dividend, add it to 53, then carry on: 535 / 99

Going ahead to step 4:
When dividing 535 by 99, we get 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 495 from 535 to get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 99

On to step 5:
99 goes into 401 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 254.0
Deduct 396 from 401 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 99

Step 6:
When dividing 53 by 99, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 2540.0
If we subtract 0 from 53, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
99 can be fit into 530 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2540.5
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
99 goes into 350 3 times with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 2540.53
Subtracting 297 from 350 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
99 can be fit into 530 5 times, resulting in a remainder of 35.
The next digit of our result is 5. 
Result so far: 2540.535
Subtracting 495 from 530 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
350 divided by 99 is 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 2540.5353
Deduct 297 from 350 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
The number 99 fits into 530 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2540.53535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 99 fits into 350 3 times, leaving a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 2540.535353
The remainder is 53 after subtracting 297 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
99 can be fit into 530 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2540.5353535
Subtract 495 from 530 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
If we divide 350 by 99, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 2540.53535353
The remainder is 53 after subtracting 297 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 2540.53535353, with a leftover of 5.3e-08.
