Let's divide 215708 by 45
Our goal is to divide 215708 by 45.

Going ahead to step 1:
45 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 45

Advancing to step 2:
When dividing 21 by 45, we get 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 45

Moving on to step 3:
45 can be fit into 215 4 times, resulting in a remainder of 35.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 180 from 215 to get 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 45

Going ahead to step 4:
45 goes into 357 7 times with a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we take 315 away from 357, we end up with 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 45

Going ahead to step 5:
45 can be fit into 420 9 times, resulting in a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 479.0
Subtracting 405 from 420 leaves us with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 45

Advancing to step 6:
45 can be fit into 158 3 times, resulting in a remainder of 23.
The next digit of our result is 3. 
Result so far: 4793.0
The remainder is 23 after subtracting 135 from 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
45 can be fit into 230 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4793.5
Deduct 225 from 230 and we're left with 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 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 4793.51
Subtract 45 from 50 to 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.

On to step 9:
If we divide 50 by 45, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 4793.511
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 4793.511 and a remainder of 0.0005.
