We look at the division of 215628 by 51 
We want to figure out the number of times 215628 can be divided by 51.

Let's proceed to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 51

Let's proceed to step 2:
If we divide 21 by 51, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 51

Going ahead to step 3:
The number 51 fits into 215 4 times, leaving a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 204 from 215 leaves us with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 51

Moving on to step 4:
If we divide 116 by 51, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 102 from 116 and we're left with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 51

Going ahead to step 5:
The number 51 fits into 142 2 times, leaving a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 422.0
Deduct 102 from 142 and we're left with 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 51

On to step 6:
The number 51 fits into 408 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 4228.0
Deduct 408 from 408 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 51, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4228.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
When dividing 0 by 51, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4228.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 4228.0 with a balance of 0.0.
