We're dividing 275721 by 87 
We want to divide 275721 by 87.

Advancing to step 1:
87 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 87

Step 2:
87 can be fit into 27 0 times, resulting in a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 87

Step 3:
87 can be fit into 275 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 261 from 275 leaves us with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 87

Going ahead to step 4:
147 divided by 87 is 1 with a remainder of 60.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 87 from 147 to get 60.
Fetch the next digit (2) from the dividend, attach it to 60 and continue: 602 / 87

Advancing to step 5:
87 goes into 602 6 times with a remainder of 80.
The next digit of our result is 6. 
Result so far: 316.0
If we subtract 522 from 602, we get 80.
Fetch the next digit (1) from the dividend, attach it to 80 and continue: 801 / 87

Going ahead to step 6:
87 goes into 801 9 times with a remainder of 18.
The next digit of our result is 9. 
Result so far: 3169.0
If we subtract 783 from 801, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
When dividing 180 by 87, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 3169.2
If we subtract 174 from 180, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
If we divide 60 by 87, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 3169.2
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
The number 87 fits into 600 6 times, leaving a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 3169.206
If we take 522 away from 600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
87 goes into 780 8 times with a remainder of 84.
The next digit of our result is 8. 
Result so far: 3169.2068
Subtracting 696 from 780 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
87 goes into 840 9 times with a remainder of 57.
Record the quotient 9 as the next digit in the result. 
Result so far: 3169.20689
Deduct 783 from 840 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
When dividing 570 by 87, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 3169.206896
Subtract 522 from 570 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
When dividing 480 by 87, we get 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 3169.2068965
Deduct 435 from 480 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 14:
87 goes into 450 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 3169.20689655
Subtracting 435 from 450 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 3169.20689655 with a remainder of 1.5e-08.
