868854 divided by 63 
Let's see how many times 63 fits into 868854.

Step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 63

Let's proceed to step 2:
63 can be fit into 86 1 times, resulting in a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 63 from 86 leaves us with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 63

Let's proceed to step 3:
When dividing 238 by 63, we get 3 with a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 189 from 238 and we're left with 49.
Fetch the next digit (8) from the dividend, attach it to 49 and continue: 498 / 63

On to step 4:
498 divided by 63 is 7 with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtract 441 from 498 to get 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 63

Going ahead to step 5:
63 goes into 575 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 1379.0
The remainder is 8 after subtracting 567 from 575.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 63

Advancing to step 6:
84 divided by 63 is 1 with a remainder of 21.
The next digit of our result is 1. 
Result so far: 13791.0
Subtract 63 from 84 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.

Let's proceed to step 7:
63 goes into 210 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 13791.3
If we take 189 away from 210, 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.

Step 8:
63 goes into 210 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 13791.33
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.

The final outcome is 13791.33, with a leftover of 0.021.
