We're dividing 86427382 by 310 
We want to figure out the number of times 86427382 can be divided by 310.

On to step 1:
The number 310 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 310

Going ahead to step 2:
310 can be fit into 86 0 times, resulting in a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 310

Step 3:
The number 310 fits into 864 2 times, leaving a remainder of 244.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 620 away from 864, we end up with 244.
Take the next digit (2) from the dividend and append it to 244, then repeat: 2442 / 310

Going ahead to step 4:
When dividing 2442 by 310, we get 7 with a remainder of 272.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 272 after subtracting 2170 from 2442.
Grab the next digit (7) from the dividend, add it to 272, then carry on: 2727 / 310

Step 5:
When dividing 2727 by 310, we get 8 with a remainder of 247.
The number 8 becomes the next digit in our result. 
Result so far: 278.0
If we subtract 2480 from 2727, we get 247.
Fetch the next digit (3) from the dividend, attach it to 247 and continue: 2473 / 310

Step 6:
If we divide 2473 by 310, we get 7 and a remainder of 303.
Put 7 as the next digit of the answer. 
Result so far: 2787.0
Deduct 2170 from 2473 and we're left with 303.
Bring next digit (8) of the dividend behind the 303 and repeat the process: 3038 / 310

Moving on to step 7:
3038 divided by 310 is 9 with a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 27879.0
If we take 2790 away from 3038, we end up with 248.
Grab the next digit (2) from the dividend, add it to 248, then carry on: 2482 / 310

Moving on to step 8:
2482 divided by 310 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 278798.0
If we take 2480 away from 2482, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
310 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 278798.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 310 is 0 with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 278798.0
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 278798.0, and the remainder is 0.2.
