We're dividing 644955 by 63 
We want to figure out the number of times 644955 can be divided by 63.

On to step 1:
If we divide 6 by 63, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 63

Step 2:
The number 63 fits into 64 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 63 from 64, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 63

Step 3:
When dividing 14 by 63, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 14, we get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 63

Step 4:
When dividing 149 by 63, we get 2 with a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 102.0
The remainder is 23 after subtracting 126 from 149.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 63

Step 5:
The number 63 fits into 235 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 1023.0
Subtract 189 from 235 to get 46.
Include the next digit (5) from the dividend after 46, then repeat: 465 / 63

Let's proceed to step 6:
The number 63 fits into 465 7 times, leaving a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 10237.0
The remainder is 24 after subtracting 441 from 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
63 goes into 240 3 times with a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 10237.3
Deduct 189 from 240 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 8:
The number 63 fits into 510 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 10237.38
If we take 504 away from 510, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
63 can be fit into 60 0 times, resulting in a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10237.38
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
63 goes into 600 9 times with a remainder of 33.
The next digit of our result is 9. 
Result so far: 10237.3809
If we take 567 away from 600, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 11:
63 can be fit into 330 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10237.38095
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
When dividing 150 by 63, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 10237.380952
If we subtract 126 from 150, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
The number 63 fits into 240 3 times, leaving a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 10237.3809523
If we take 189 away from 240, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 14:
63 can be fit into 510 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 10237.38095238
If we subtract 504 from 510, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 10237.38095238 with a balance of 6e-09.
