12550286 ÷ 825 
Our goal is to divide 12550286 by 825.

Going ahead to step 1:
825 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 825

Going ahead to step 2:
825 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 825

Moving on to step 3:
If we divide 125 by 825, we get 0 and a remainder of 125.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 125, we end up with 125.
Include the next digit (5) from the dividend after 125, then repeat: 1255 / 825

Step 4:
When dividing 1255 by 825, we get 1 with a remainder of 430.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 825 from 1255 and we're left with 430.
Bring next digit (0) of the dividend behind the 430 and repeat the process: 4300 / 825

Step 5:
If we divide 4300 by 825, we get 5 and a remainder of 175.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 4125 from 4300 leaves us with 175.
Bring next digit (2) of the dividend behind the 175 and repeat the process: 1752 / 825

Let's proceed to step 6:
The number 825 fits into 1752 2 times, leaving a remainder of 102.
Use 2 as the next digit of our solution. 
Result so far: 152.0
Subtract 1650 from 1752 to get 102.
Take the next digit (8) from the dividend and append it to 102, then repeat: 1028 / 825

Going ahead to step 7:
When dividing 1028 by 825, we get 1 with a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 1521.0
Subtracting 825 from 1028 leaves us with 203.
Grab the next digit (6) from the dividend, add it to 203, then carry on: 2036 / 825

Let's proceed to step 8:
825 goes into 2036 2 times with a remainder of 386.
Put 2 as the next digit of the answer. 
Result so far: 15212.0
Subtract 1650 from 2036 to get 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Let's proceed to step 9:
825 can be fit into 3860 4 times, resulting in a remainder of 560.
Record the quotient 4 as the next digit in the result. 
Result so far: 15212.4
Subtract 3300 from 3860 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
5600 divided by 825 is 6 with a remainder of 650.
Put 6 as the next digit of the answer. 
Result so far: 15212.46
Subtracting 4950 from 5600 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Moving on to step 11:
When dividing 6500 by 825, we get 7 with a remainder of 725.
Use 7 as the next digit of our solution. 
Result so far: 15212.467
The remainder is 725 after subtracting 5775 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Step 12:
7250 divided by 825 is 8 with a remainder of 650.
Write down 8 as next digit of the result. 
Result so far: 15212.4678
Subtracting 6600 from 7250 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 13:
If we divide 6500 by 825, we get 7 and a remainder of 725.
The next digit of our result is 7. 
Result so far: 15212.46787
The remainder is 725 after subtracting 5775 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 14:
7250 divided by 825 is 8 with a remainder of 650.
Put 8 as the next digit of the answer. 
Result so far: 15212.467878
Subtracting 6600 from 7250 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

On to step 15:
The number 825 fits into 6500 7 times, leaving a remainder of 725.
The next digit of our result is 7. 
Result so far: 15212.4678787
The remainder is 725 after subtracting 5775 from 6500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 16:
825 can be fit into 7250 8 times, resulting in a remainder of 650.
Write down 8 as next digit of the result. 
Result so far: 15212.46787878
The remainder is 650 after subtracting 6600 from 7250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final result is 15212.46787878 with a remainder of 6.5e-07.
