Let's divide 643428 by 63
Our goal is to divide 643428 by 63.

Advancing to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 63

Going ahead to step 2:
63 goes into 64 1 times with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 63 from 64, we get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 63

On to step 3:
63 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 63

Let's proceed to step 4:
63 can be fit into 134 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtract 126 from 134 to get 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 63

Advancing to step 5:
The number 63 fits into 82 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1021.0
If we take 63 away from 82, we end up with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 63

Let's proceed to step 6:
63 can be fit into 198 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 10213.0
The remainder is 9 after subtracting 189 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 63, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 10213.1
The remainder is 27 after subtracting 63 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
The number 63 fits into 270 4 times, leaving a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 10213.14
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
63 can be fit into 180 2 times, resulting in a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 10213.142
The remainder is 54 after subtracting 126 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 10:
63 can be fit into 540 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 10213.1428
If we subtract 504 from 540, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
When dividing 360 by 63, we get 5 with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 10213.14285
If we subtract 315 from 360, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 12:
The number 63 fits into 450 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 10213.142857
Deduct 441 from 450 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 13:
63 goes into 90 1 times with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 10213.1428571
If we subtract 63 from 90, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 14:
63 goes into 270 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 10213.14285714
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 10213.14285714 with a remainder of 1.8e-08.
