63697816 divided by 668 
Let's see how many times 668 fits into 63697816.

Step 1:
6 divided by 668 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 668

Advancing to step 2:
When dividing 63 by 668, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Take the next digit (6) from the dividend and append it to 63, then repeat: 636 / 668

Advancing to step 3:
If we divide 636 by 668, we get 0 and a remainder of 636.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 636 to get 636.
Include the next digit (9) from the dividend after 636, then repeat: 6369 / 668

On to step 4:
When dividing 6369 by 668, we get 9 with a remainder of 357.
The next digit of our result is 9. 
Result so far: 9.0
If we take 6012 away from 6369, we end up with 357.
Fetch the next digit (7) from the dividend, attach it to 357 and continue: 3577 / 668

On to step 5:
The number 668 fits into 3577 5 times, leaving a remainder of 237.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 3340 away from 3577, we end up with 237.
Bring next digit (8) of the dividend behind the 237 and repeat the process: 2378 / 668

Going ahead to step 6:
2378 divided by 668 is 3 with a remainder of 374.
Put 3 as the next digit of the answer. 
Result so far: 953.0
Subtracting 2004 from 2378 leaves us with 374.
Append the next digit (1) from the dividend to 374 and continue with: 3741 / 668

Going ahead to step 7:
3741 divided by 668 is 5 with a remainder of 401.
Put 5 as the next digit of the answer. 
Result so far: 9535.0
Deduct 3340 from 3741 and we're left with 401.
Fetch the next digit (6) from the dividend, attach it to 401 and continue: 4016 / 668

Going ahead to step 8:
668 can be fit into 4016 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 95356.0
If we take 4008 away from 4016, we end up with 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 9:
If we divide 80 by 668, we get 0 and a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 95356.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
When dividing 800 by 668, we get 1 with a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 95356.01
If we take 668 away from 800, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 11:
If we divide 1320 by 668, we get 1 and a remainder of 652.
The next digit of our result is 1. 
Result so far: 95356.011
If we take 668 away from 1320, we end up with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

After the division, we end up with 95356.011 and a remainder of 0.0652.
