51230 ÷ 63 
Our goal is to divide 51230 by 63.

Going ahead to step 1:
5 divided by 63 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 63

Moving on to step 2:
If we divide 51 by 63, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 63

Moving on to step 3:
If we divide 512 by 63, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 504 from 512, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 63

Let's proceed to step 4:
The number 63 fits into 83 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 63 away from 83, we end up with 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 63

Advancing to step 5:
63 goes into 200 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 813.0
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 6:
63 can be fit into 110 1 times, resulting in a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 813.1
If we take 63 away from 110, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 7:
If we divide 470 by 63, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 813.17
If we take 441 away from 470, we end up 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.

Advancing to step 8:
If we divide 290 by 63, we get 4 and a remainder of 38.
Use 4 as the next digit of our solution. 
Result so far: 813.174
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 9:
63 goes into 380 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 813.1746
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
63 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 813.1746
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
63 can be fit into 200 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 813.174603
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
63 can be fit into 110 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 813.1746031
If we subtract 63 from 110, we 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.

Step 13:
470 divided by 63 is 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 813.17460317
Subtracting 441 from 470 leaves us 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.

Our division results in 813.17460317 with a remaining 2.9e-08.
