838803 ÷ 63 
Our goal is to divide 838803 by 63.

Moving on to step 1:
If we divide 8 by 63, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 63

On to step 2:
The number 63 fits into 83 1 times, leaving a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 63 from 83 leaves us with 20.
Grab the next digit (8) from the dividend, add it to 20, then carry on: 208 / 63

On to step 3:
63 goes into 208 3 times with a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 19 after subtracting 189 from 208.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 63

On to step 4:
If we divide 198 by 63, we get 3 and a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 133.0
Subtract 189 from 198 to get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 63

Let's proceed to step 5:
The number 63 fits into 90 1 times, leaving a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 1331.0
The remainder is 27 after subtracting 63 from 90.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 63

Moving on to step 6:
If we divide 273 by 63, we get 4 and a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 13314.0
If we subtract 252 from 273, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
63 goes into 210 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 13314.3
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
63 can be fit into 210 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 13314.33
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 13314.33 with a remainder of 0.021.
