215464 ÷ 45 
Our goal is to divide 215464 by 45.

Advancing to step 1:
45 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
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 45

On to step 2:
The number 45 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 45

On to step 3:
When dividing 215 by 45, we get 4 with a remainder of 35.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 35 after subtracting 180 from 215.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 45

On to step 4:
When dividing 354 by 45, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 315 from 354 to get 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 45

On to step 5:
45 can be fit into 396 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 478.0
Subtracting 360 from 396 leaves us with 36.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 45

Let's proceed to step 6:
The number 45 fits into 364 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 4788.0
Subtracting 360 from 364 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 45, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4788.0
If we take 0 away from 40, we end up 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.

Step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 4788.08
Subtracting 360 from 400 leaves us 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.

Let's proceed to step 9:
45 can be fit into 400 8 times, resulting in a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 4788.088
Subtracting 360 from 400 leaves us 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.

After the division, we end up with 4788.088 and a remainder of 0.004.
