64179965 ÷ 665 
We want to figure out the number of times 64179965 can be divided by 665.

On to step 1:
The number 665 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 665

On to step 2:
665 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 665

Let's proceed to step 3:
If we divide 641 by 665, we get 0 and a remainder of 641.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 641, we get 641.
Grab the next digit (7) from the dividend, add it to 641, then carry on: 6417 / 665

Going ahead to step 4:
665 can be fit into 6417 9 times, resulting in a remainder of 432.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 5985 from 6417 leaves us with 432.
Append the next digit (9) from the dividend to 432 and continue with: 4329 / 665

Advancing to step 5:
If we divide 4329 by 665, we get 6 and a remainder of 339.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
If we take 3990 away from 4329, we end up with 339.
Include the next digit (9) from the dividend after 339, then repeat: 3399 / 665

Let's proceed to step 6:
If we divide 3399 by 665, we get 5 and a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 965.0
If we subtract 3325 from 3399, we get 74.
Bring next digit (6) of the dividend behind the 74 and repeat the process: 746 / 665

On to step 7:
If we divide 746 by 665, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 9651.0
If we take 665 away from 746, we end up with 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 665

Let's proceed to step 8:
815 divided by 665 is 1 with a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 96511.0
Subtracting 665 from 815 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 9:
When dividing 1500 by 665, we get 2 with a remainder of 170.
Record the quotient 2 as the next digit in the result. 
Result so far: 96511.2
Subtracting 1330 from 1500 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 10:
If we divide 1700 by 665, we get 2 and a remainder of 370.
The number 2 becomes the next digit in our result. 
Result so far: 96511.22
Deduct 1330 from 1700 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final outcome is 96511.22, with a leftover of 0.37.
