We divide 51665 by 43
Let's see how many times 43 fits into 51665.

On to step 1:
5 divided by 43 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 43

Moving on to step 2:
51 divided by 43 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 43 from 51 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 43

Going ahead to step 3:
86 divided by 43 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 86 from 86 to get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 43

Let's proceed to step 4:
When dividing 6 by 43, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 43

Going ahead to step 5:
43 goes into 65 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1201.0
Subtracting 43 from 65 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 6:
220 divided by 43 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 1201.5
If we subtract 215 from 220, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 43, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1201.51
If we subtract 43 from 50, we 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 8:
If we divide 70 by 43, we get 1 and a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1201.511
The remainder is 27 after subtracting 43 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 1201.511, with a leftover of 0.0027.
