We look at the division of 21449 by 63 
We want to figure out the number of times 21449 can be divided by 63.

Advancing to step 1:
The number 63 fits into 2 0 times, leaving 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.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 63

Moving on to step 2:
If we divide 21 by 63, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 63

Going ahead to step 3:
When dividing 214 by 63, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 189 from 214, we get 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 63

Let's proceed to step 4:
The number 63 fits into 254 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 252 from 254 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 63

Advancing to step 5:
The number 63 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 340.0
The remainder is 29 after subtracting 0 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 6:
290 divided by 63 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 340.4
Subtracting 252 from 290 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
If we divide 380 by 63, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 340.46
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 63 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 340.46
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 63 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 340.4603
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
63 can be fit into 110 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 340.46031
Subtract 63 from 110 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
The number 63 fits into 470 7 times, leaving a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 340.460317
Deduct 441 from 470 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
When dividing 290 by 63, we get 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 340.4603174
If we take 252 away from 290, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 13:
If we divide 380 by 63, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 340.46031746
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 340.46031746, with a leftover of 2e-09.
