We divide 644449 by 63
Let's see how many times 63 fits into 644449.

Step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 63

Going ahead to step 2:
64 divided by 63 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 63 from 64 and we're left with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 63

On to step 3:
If we divide 14 by 63, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 63

Moving on to step 4:
The number 63 fits into 144 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 18 after subtracting 126 from 144.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 63

Advancing to step 5:
The number 63 fits into 184 2 times, leaving a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 1022.0
Deduct 126 from 184 and we're left with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 63

Going ahead to step 6:
63 can be fit into 589 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 10229.0
Subtract 567 from 589 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
If we divide 220 by 63, we get 3 and a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 10229.3
If we subtract 189 from 220, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
63 goes into 310 4 times with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 10229.34
Subtract 252 from 310 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
When dividing 580 by 63, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 10229.349
If we take 567 away from 580, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
63 goes into 130 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10229.3492
If we take 126 away from 130, we end up 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.

Moving on to step 11:
63 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 10229.3492
Deduct 0 from 40 and we're left 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.

On to step 12:
The number 63 fits into 400 6 times, leaving a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 10229.349206
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 13:
220 divided by 63 is 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 10229.3492063
Subtracting 189 from 220 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
63 can be fit into 310 4 times, resulting in a remainder of 58.
The next digit of our result is 4. 
Result so far: 10229.34920634
Deduct 252 from 310 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final outcome is 10229.34920634, with a leftover of 5.8e-08.
