We look at the division of 686645 by 63 
We want to divide 686645 by 63.

Advancing to step 1:
When dividing 6 by 63, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 63

Advancing to step 2:
If we divide 68 by 63, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 63 away from 68, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 63

Going ahead to step 3:
When dividing 56 by 63, we get 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 56, we end up with 56.
Fetch the next digit (6) from the dividend, attach it to 56 and continue: 566 / 63

Going ahead to step 4:
When dividing 566 by 63, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 108.0
If we subtract 504 from 566, we get 62.
Bring next digit (4) of the dividend behind the 62 and repeat the process: 624 / 63

Step 5:
The number 63 fits into 624 9 times, leaving a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
If we subtract 567 from 624, we get 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 63

Advancing to step 6:
63 can be fit into 575 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 10899.0
Subtract 567 from 575 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 63 fits into 80 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 10899.1
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
The number 63 fits into 170 2 times, leaving a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 10899.12
Deduct 126 from 170 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
63 goes into 440 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 10899.126
Subtract 378 from 440 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
When dividing 620 by 63, we get 9 with a remainder of 53.
Use 9 as the next digit of our solution. 
Result so far: 10899.1269
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 11:
The number 63 fits into 530 8 times, leaving a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 10899.12698
Subtracting 504 from 530 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
If we divide 260 by 63, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10899.126984
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
63 goes into 80 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 10899.1269841
If we subtract 63 from 80, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
If we divide 170 by 63, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 10899.12698412
Subtract 126 from 170 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 10899.12698412 and a remainder of 4.4e-08.
