Let's divide 216489 by 63
Let's see how many times 63 fits into 216489.

Step 1:
When dividing 2 by 63, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
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 / 63

Advancing to step 2:
If we divide 21 by 63, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 63

Let's proceed to step 3:
If we divide 216 by 63, we get 3 and a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 189 from 216 leaves us with 27.
Fetch the next digit (4) from the dividend, attach it to 27 and continue: 274 / 63

Going ahead to step 4:
The number 63 fits into 274 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
The remainder is 22 after subtracting 252 from 274.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 63

Moving on to step 5:
63 goes into 228 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 343.0
If we take 189 away from 228, we end up with 39.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 63

Moving on to step 6:
63 can be fit into 399 6 times, resulting in a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 3436.0
If we subtract 378 from 399, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 63 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3436.3
If we take 189 away from 210, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
The number 63 fits into 210 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 3436.33
The remainder is 21 after subtracting 189 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 3436.33 with a remaining 0.021.
