We're dividing 215928 by 51 
Let's see how many times 51 fits into 215928.

Moving on to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 51

Step 2:
51 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 51

Going ahead to step 3:
The number 51 fits into 215 4 times, leaving a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 204 from 215 to get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 51

On to step 4:
When dividing 119 by 51, we get 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 42.0
The remainder is 17 after subtracting 102 from 119.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 51

Moving on to step 5:
If we divide 172 by 51, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 423.0
Subtract 153 from 172 to get 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 51

Advancing to step 6:
When dividing 198 by 51, we get 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 4233.0
The remainder is 45 after subtracting 153 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 4233.8
The remainder is 42 after subtracting 408 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
When dividing 420 by 51, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 4233.88
Subtracting 408 from 420 leaves us with 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 final outcome is 4233.88, with a leftover of 0.012.
