We're dividing 15940 by 87 
Let's see how many times 87 fits into 15940.

Let's proceed to step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 87

Moving on to step 2:
87 can be fit into 15 0 times, resulting in a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 87

On to step 3:
When dividing 159 by 87, we get 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 87 away from 159, we end up with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 87

Advancing to step 4:
87 can be fit into 724 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 18.0
Subtract 696 from 724 to get 28.
Bring next digit (0) of the dividend behind the 28 and repeat the process: 280 / 87

On to step 5:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 183.0
If we take 261 away from 280, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 6:
190 divided by 87 is 2 with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 183.2
If we subtract 174 from 190, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
When dividing 160 by 87, we get 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 183.21
If we take 87 away from 160, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
87 goes into 730 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 183.218
Deduct 696 from 730 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
87 goes into 340 3 times with a remainder of 79.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.2183
Deduct 261 from 340 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 10:
If we divide 790 by 87, we get 9 and a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 183.21839
Subtract 783 from 790 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
70 divided by 87 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 183.21839
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
87 goes into 700 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 183.2183908
If we subtract 696 from 700, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
The number 87 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 183.2183908
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 183.2183908 with a remainder of 4e-08.
