We look at the division of 243210 by 63 
Let's see how many times 63 fits into 243210.

Going ahead to step 1:
63 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 63

Step 2:
63 can be fit into 24 0 times, resulting in a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 63

Step 3:
63 can be fit into 243 3 times, resulting in a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 189 from 243, we get 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 63

Let's proceed to step 4:
When dividing 542 by 63, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 38.0
If we take 504 away from 542, we end up with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 63

Going ahead to step 5:
63 can be fit into 381 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 386.0
If we subtract 378 from 381, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 63

On to step 6:
When dividing 30 by 63, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3860.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
63 goes into 300 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 3860.4
Subtract 252 from 300 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
The number 63 fits into 480 7 times, leaving a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 3860.47
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
If we divide 390 by 63, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 3860.476
Deduct 378 from 390 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
63 can be fit into 120 1 times, resulting in a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 3860.4761
Subtract 63 from 120 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 11:
When dividing 570 by 63, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3860.47619
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 12:
The number 63 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3860.47619
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 13:
If we divide 300 by 63, we get 4 and a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 3860.4761904
Subtract 252 from 300 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
If we divide 480 by 63, we get 7 and a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 3860.47619047
If we take 441 away from 480, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

In conclusion, the division gives 3860.47619047 with a balance of 3.9e-08.
