We're dividing 27408251 by 863 
We want to figure out the number of times 27408251 can be divided by 863.

Going ahead to step 1:
2 divided by 863 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 863

On to step 2:
27 divided by 863 is 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 863

On to step 3:
863 goes into 274 0 times with a remainder of 274.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 274 and we're left with 274.
Bring next digit (0) of the dividend behind the 274 and repeat the process: 2740 / 863

Moving on to step 4:
When dividing 2740 by 863, we get 3 with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 151 after subtracting 2589 from 2740.
Bring next digit (8) of the dividend behind the 151 and repeat the process: 1518 / 863

Step 5:
863 can be fit into 1518 1 times, resulting in a remainder of 655.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtracting 863 from 1518 leaves us with 655.
Grab the next digit (2) from the dividend, add it to 655, then carry on: 6552 / 863

On to step 6:
If we divide 6552 by 863, we get 7 and a remainder of 511.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtracting 6041 from 6552 leaves us with 511.
Grab the next digit (5) from the dividend, add it to 511, then carry on: 5115 / 863

Step 7:
863 goes into 5115 5 times with a remainder of 800.
Put 5 as the next digit of the answer. 
Result so far: 3175.0
Deduct 4315 from 5115 and we're left with 800.
Grab the next digit (1) from the dividend, add it to 800, then carry on: 8001 / 863

Moving on to step 8:
863 goes into 8001 9 times with a remainder of 234.
Use 9 as the next digit of our solution. 
Result so far: 31759.0
Subtracting 7767 from 8001 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 9:
The number 863 fits into 2340 2 times, leaving a remainder of 614.
The number 2 becomes the next digit in our result. 
Result so far: 31759.2
Subtracting 1726 from 2340 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 10:
The number 863 fits into 6140 7 times, leaving a remainder of 99.
The next digit of our result is 7. 
Result so far: 31759.27
If we subtract 6041 from 6140, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Advancing to step 11:
990 divided by 863 is 1 with a remainder of 127.
Put 1 as the next digit of the answer. 
Result so far: 31759.271
Subtracting 863 from 990 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 12:
If we divide 1270 by 863, we get 1 and a remainder of 407.
Write down 1 as next digit of the result. 
Result so far: 31759.2711
Subtract 863 from 1270 to get 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

After the division, we end up with 31759.2711 and a remainder of 0.00407.
