63886315 ÷ 665 
We're looking to find how many times 665 goes into 63886315.

Going ahead to step 1:
The number 665 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 665

Let's proceed to step 2:
If we divide 63 by 665, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 665

Advancing to step 3:
665 goes into 638 0 times with a remainder of 638.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 638 and we're left with 638.
Append the next digit (8) from the dividend to 638 and continue with: 6388 / 665

On to step 4:
665 goes into 6388 9 times with a remainder of 403.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 403 after subtracting 5985 from 6388.
Append the next digit (6) from the dividend to 403 and continue with: 4036 / 665

Step 5:
If we divide 4036 by 665, we get 6 and a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
If we take 3990 away from 4036, we end up with 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 665

On to step 6:
665 goes into 463 0 times with a remainder of 463.
Put 0 as the next digit of the answer. 
Result so far: 960.0
Deduct 0 from 463 and we're left with 463.
Take the next digit (1) from the dividend and append it to 463, then repeat: 4631 / 665

Going ahead to step 7:
If we divide 4631 by 665, we get 6 and a remainder of 641.
Put 6 as the next digit of the answer. 
Result so far: 9606.0
If we subtract 3990 from 4631, we get 641.
Include the next digit (5) from the dividend after 641, then repeat: 6415 / 665

On to step 8:
665 can be fit into 6415 9 times, resulting in a remainder of 430.
Use 9 as the next digit of our solution. 
Result so far: 96069.0
The remainder is 430 after subtracting 5985 from 6415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

On to step 9:
665 can be fit into 4300 6 times, resulting in a remainder of 310.
Use 6 as the next digit of our solution. 
Result so far: 96069.6
Deduct 3990 from 4300 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 10:
If we divide 3100 by 665, we get 4 and a remainder of 440.
The next digit of our result is 4. 
Result so far: 96069.64
Subtracting 2660 from 3100 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 11:
When dividing 4400 by 665, we get 6 with a remainder of 410.
Write down 6 as next digit of the result. 
Result so far: 96069.646
The remainder is 410 after subtracting 3990 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 12:
The number 665 fits into 4100 6 times, leaving a remainder of 110.
Write down 6 as next digit of the result. 
Result so far: 96069.6466
If we subtract 3990 from 4100, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 96069.6466, with a leftover of 0.0011.
