We're dividing 5120871 by 276 
We want to figure out the number of times 5120871 can be divided by 276.

Going ahead to step 1:
5 divided by 276 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 276

Step 2:
The number 276 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 276

Moving on to step 3:
276 can be fit into 512 1 times, resulting in a remainder of 236.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 276 from 512 leaves us with 236.
Bring next digit (0) of the dividend behind the 236 and repeat the process: 2360 / 276

Let's proceed to step 4:
2360 divided by 276 is 8 with a remainder of 152.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 2208 from 2360 and we're left with 152.
Grab the next digit (8) from the dividend, add it to 152, then carry on: 1528 / 276

Moving on to step 5:
276 can be fit into 1528 5 times, resulting in a remainder of 148.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtracting 1380 from 1528 leaves us with 148.
Append the next digit (7) from the dividend to 148 and continue with: 1487 / 276

Step 6:
1487 divided by 276 is 5 with a remainder of 107.
Use 5 as the next digit of our solution. 
Result so far: 1855.0
If we take 1380 away from 1487, we end up with 107.
Append the next digit (1) from the dividend to 107 and continue with: 1071 / 276

Let's proceed to step 7:
276 can be fit into 1071 3 times, resulting in a remainder of 243.
Put 3 as the next digit of the answer. 
Result so far: 18553.0
If we subtract 828 from 1071, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Advancing to step 8:
When dividing 2430 by 276, we get 8 with a remainder of 222.
Record the quotient 8 as the next digit in the result. 
Result so far: 18553.8
Deduct 2208 from 2430 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 9:
276 can be fit into 2220 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 18553.88
If we subtract 2208 from 2220, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 18553.88, and the remainder is 0.012.
