12863548 ÷ 252 
We want to figure out the number of times 12863548 can be divided by 252.

Let's proceed to step 1:
1 divided by 252 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 252

Let's proceed to step 2:
When dividing 12 by 252, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 252

Going ahead to step 3:
252 goes into 128 0 times with a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 128 after subtracting 0 from 128.
Fetch the next digit (6) from the dividend, attach it to 128 and continue: 1286 / 252

Step 4:
252 can be fit into 1286 5 times, resulting in a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 1260 away from 1286, we end up with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 252

Moving on to step 5:
252 goes into 263 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 252 from 263 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 252

On to step 6:
252 can be fit into 115 0 times, resulting in a remainder of 115.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Subtract 0 from 115 to get 115.
Include the next digit (4) from the dividend after 115, then repeat: 1154 / 252

On to step 7:
1154 divided by 252 is 4 with a remainder of 146.
Put 4 as the next digit of the answer. 
Result so far: 5104.0
Subtract 1008 from 1154 to get 146.
Fetch the next digit (8) from the dividend, attach it to 146 and continue: 1468 / 252

Step 8:
252 goes into 1468 5 times with a remainder of 208.
Write down 5 as next digit of the result. 
Result so far: 51045.0
The remainder is 208 after subtracting 1260 from 1468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 9:
When dividing 2080 by 252, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 51045.8
If we subtract 2016 from 2080, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
When dividing 640 by 252, we get 2 with a remainder of 136.
The number 2 becomes the next digit in our result. 
Result so far: 51045.82
The remainder is 136 after subtracting 504 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 11:
1360 divided by 252 is 5 with a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 51045.825
Deduct 1260 from 1360 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 12:
If we divide 1000 by 252, we get 3 and a remainder of 244.
Write down 3 as next digit of the result. 
Result so far: 51045.8253
Subtracting 756 from 1000 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 13:
If we divide 2440 by 252, we get 9 and a remainder of 172.
Put 9 as the next digit of the answer. 
Result so far: 51045.82539
The remainder is 172 after subtracting 2268 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 14:
252 goes into 1720 6 times with a remainder of 208.
The next digit of our result is 6. 
Result so far: 51045.825396
If we subtract 1512 from 1720, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 15:
The number 252 fits into 2080 8 times, leaving a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 51045.8253968
Subtracting 2016 from 2080 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
252 goes into 640 2 times with a remainder of 136.
The next digit of our result is 2. 
Result so far: 51045.82539682
Subtract 504 from 640 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 51045.82539682 with a remainder of 1.36e-07.
