We look at the division of 646466 by 63 
Our goal is to divide 646466 by 63.

Let's proceed to step 1:
63 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 63

On to 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 (6) from the dividend, attach it to 1 and continue: 16 / 63

Let's proceed to step 3:
When dividing 16 by 63, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 16 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 63

Advancing to step 4:
If we divide 164 by 63, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 102.0
The remainder is 38 after subtracting 126 from 164.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 63

On to step 5:
63 goes into 386 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1026.0
Subtract 378 from 386 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 63

Let's proceed to step 6:
If we divide 86 by 63, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 10261.0
Subtract 63 from 86 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
The number 63 fits into 230 3 times, leaving a remainder of 41.
The next digit of our result is 3. 
Result so far: 10261.3
Subtracting 189 from 230 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 8:
63 goes into 410 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 10261.36
Subtracting 378 from 410 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
63 can be fit into 320 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 10261.365
Subtracting 315 from 320 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
50 divided by 63 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 10261.365
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 11:
If we divide 500 by 63, we get 7 and a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 10261.36507
Subtract 441 from 500 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 12:
When dividing 590 by 63, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 10261.365079
If we subtract 567 from 590, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
When dividing 230 by 63, we get 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 10261.3650793
If we take 189 away from 230, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 14:
410 divided by 63 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 10261.36507936
Subtract 378 from 410 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 10261.36507936 with a remainder of 3.2e-08.
