We're dividing 688485 by 63 
Let's see how many times 63 fits into 688485.

Going ahead to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 63

Advancing to step 2:
If we divide 68 by 63, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 63 from 68, we get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 63

Advancing to step 3:
63 goes into 58 0 times with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 58, we get 58.
Bring next digit (4) of the dividend behind the 58 and repeat the process: 584 / 63

Step 4:
If we divide 584 by 63, we get 9 and a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we take 567 away from 584, we end up with 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 63

Moving on to step 5:
63 can be fit into 178 2 times, resulting in a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 1092.0
Deduct 126 from 178 and we're left with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 63

On to step 6:
If we divide 525 by 63, we get 8 and a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 10928.0
Subtracting 504 from 525 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.

Step 7:
When dividing 210 by 63, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 10928.3
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.

Step 8:
If we divide 210 by 63, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 10928.33
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 result is 10928.33 with a remainder of 0.021.
