87124495 divided by 252 
We want to figure out the number of times 87124495 can be divided by 252.

On to step 1:
The number 252 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 252

On to step 2:
When dividing 87 by 252, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (1) from the dividend to 87 and continue with: 871 / 252

On to step 3:
When dividing 871 by 252, we get 3 with a remainder of 115.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 756 from 871 and we're left with 115.
Bring next digit (2) of the dividend behind the 115 and repeat the process: 1152 / 252

Step 4:
252 goes into 1152 4 times with a remainder of 144.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 1008 from 1152, we get 144.
Grab the next digit (4) from the dividend, add it to 144, then carry on: 1444 / 252

Moving on to step 5:
252 can be fit into 1444 5 times, resulting in a remainder of 184.
Record the quotient 5 as the next digit in the result. 
Result so far: 345.0
Subtracting 1260 from 1444 leaves us with 184.
Take the next digit (4) from the dividend and append it to 184, then repeat: 1844 / 252

Moving on to step 6:
The number 252 fits into 1844 7 times, leaving a remainder of 80.
The next digit of our result is 7. 
Result so far: 3457.0
The remainder is 80 after subtracting 1764 from 1844.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 252

Moving on to step 7:
The number 252 fits into 809 3 times, leaving a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 34573.0
The remainder is 53 after subtracting 756 from 809.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 252

Going ahead to step 8:
If we divide 535 by 252, we get 2 and a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 345732.0
If we subtract 504 from 535, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
310 divided by 252 is 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 345732.1
Subtracting 252 from 310 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
580 divided by 252 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 345732.12
If we subtract 504 from 580, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
252 goes into 760 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 345732.123
Subtract 756 from 760 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
40 divided by 252 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 345732.123
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
252 goes into 400 1 times with a remainder of 148.
Write down 1 as next digit of the result. 
Result so far: 345732.12301
Subtract 252 from 400 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 14:
1480 divided by 252 is 5 with a remainder of 220.
The number 5 becomes the next digit in our result. 
Result so far: 345732.123015
Subtracting 1260 from 1480 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 15:
When dividing 2200 by 252, we get 8 with a remainder of 184.
Put 8 as the next digit of the answer. 
Result so far: 345732.1230158
If we subtract 2016 from 2200, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 16:
252 goes into 1840 7 times with a remainder of 76.
Write down 7 as next digit of the result. 
Result so far: 345732.12301587
The remainder is 76 after subtracting 1764 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final outcome is 345732.12301587, with a leftover of 7.6e-08.
