51240001 ÷ 252 
We want to divide 51240001 by 252.

Moving on to step 1:
When dividing 5 by 252, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 252

Advancing to step 2:
252 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 252

On to step 3:
The number 252 fits into 512 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 8 after subtracting 504 from 512.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 252

Going ahead to step 4:
252 goes into 84 0 times with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 84, we get 84.
Grab the next digit (0) from the dividend, add it to 84, then carry on: 840 / 252

Moving on to step 5:
If we divide 840 by 252, we get 3 and a remainder of 84.
The next digit of our result is 3. 
Result so far: 203.0
If we take 756 away from 840, we end up with 84.
Include the next digit (0) from the dividend after 84, then repeat: 840 / 252

Going ahead to step 6:
840 divided by 252 is 3 with a remainder of 84.
The next digit of our result is 3. 
Result so far: 2033.0
If we take 756 away from 840, we end up with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 252

Let's proceed to step 7:
252 goes into 840 3 times with a remainder of 84.
The next digit of our result is 3. 
Result so far: 20333.0
Deduct 756 from 840 and we're left with 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 252

On to step 8:
If we divide 841 by 252, we get 3 and a remainder of 85.
The next digit of our result is 3. 
Result so far: 203333.0
If we subtract 756 from 841, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 9:
The number 252 fits into 850 3 times, leaving a remainder of 94.
Use 3 as the next digit of our solution. 
Result so far: 203333.3
Subtract 756 from 850 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 10:
When dividing 940 by 252, we get 3 with a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 203333.33
Deduct 756 from 940 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The quotient of the division is 203333.33, and the remainder is 0.184.
