802137 ÷ 63 
Our goal is to divide 802137 by 63.

Advancing to step 1:
When dividing 8 by 63, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 63

On to step 2:
When dividing 80 by 63, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 17 after subtracting 63 from 80.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 63

On to step 3:
63 goes into 172 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 126 from 172 and we're left with 46.
Append the next digit (1) from the dividend to 46 and continue with: 461 / 63

Going ahead to step 4:
63 goes into 461 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtract 441 from 461 to get 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 63

Advancing to step 5:
If we divide 203 by 63, we get 3 and a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 1273.0
Deduct 189 from 203 and we're left with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 63

Advancing to step 6:
When dividing 147 by 63, we get 2 with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12732.0
If we take 126 away from 147, we end up 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.

Let's proceed to step 7:
63 can be fit into 210 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 12732.3
Deduct 189 from 210 and we're left 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.

Step 8:
When dividing 210 by 63, we get 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 12732.33
The remainder is 21 after subtracting 189 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 12732.33 and a remainder of 0.021.
