12316249 ÷ 802 
We want to divide 12316249 by 802.

On to step 1:
802 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 802

On to step 2:
802 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 802

Let's proceed to step 3:
802 goes into 123 0 times with a remainder of 123.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 123 to get 123.
Grab the next digit (1) from the dividend, add it to 123, then carry on: 1231 / 802

Going ahead to step 4:
802 goes into 1231 1 times with a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 429 after subtracting 802 from 1231.
Include the next digit (6) from the dividend after 429, then repeat: 4296 / 802

Advancing to step 5:
4296 divided by 802 is 5 with a remainder of 286.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 4010 from 4296 to get 286.
Append the next digit (2) from the dividend to 286 and continue with: 2862 / 802

Advancing to step 6:
2862 divided by 802 is 3 with a remainder of 456.
The next digit of our result is 3. 
Result so far: 153.0
Subtract 2406 from 2862 to get 456.
Bring next digit (4) of the dividend behind the 456 and repeat the process: 4564 / 802

Moving on to step 7:
802 can be fit into 4564 5 times, resulting in a remainder of 554.
Use 5 as the next digit of our solution. 
Result so far: 1535.0
If we take 4010 away from 4564, we end up with 554.
Take the next digit (9) from the dividend and append it to 554, then repeat: 5549 / 802

Advancing to step 8:
When dividing 5549 by 802, we get 6 with a remainder of 737.
Write down 6 as next digit of the result. 
Result so far: 15356.0
The remainder is 737 after subtracting 4812 from 5549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

Advancing to step 9:
The number 802 fits into 7370 9 times, leaving a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 15356.9
Subtract 7218 from 7370 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 10:
802 goes into 1520 1 times with a remainder of 718.
Use 1 as the next digit of our solution. 
Result so far: 15356.91
If we take 802 away from 1520, we end up with 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 11:
7180 divided by 802 is 8 with a remainder of 764.
Use 8 as the next digit of our solution. 
Result so far: 15356.918
The remainder is 764 after subtracting 6416 from 7180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Moving on to step 12:
The number 802 fits into 7640 9 times, leaving a remainder of 422.
The number 9 becomes the next digit in our result. 
Result so far: 15356.9189
Subtract 7218 from 7640 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 13:
The number 802 fits into 4220 5 times, leaving a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 15356.91895
Deduct 4010 from 4220 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 14:
If we divide 2100 by 802, we get 2 and a remainder of 496.
Record the quotient 2 as the next digit in the result. 
Result so far: 15356.918952
If we subtract 1604 from 2100, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 15:
The number 802 fits into 4960 6 times, leaving a remainder of 148.
The next digit of our result is 6. 
Result so far: 15356.9189526
Subtract 4812 from 4960 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.

Advancing to step 16:
802 can be fit into 1480 1 times, resulting in a remainder of 678.
Put 1 as the next digit of the answer. 
Result so far: 15356.91895261
If we take 802 away from 1480, we end up with 678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6780, and continue the process.

Our division results in 15356.91895261 with a remaining 6.78e-07.
