Let's divide 66417558 by 636
We want to figure out the number of times 66417558 can be divided by 636.

Step 1:
The number 636 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
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 636

On to step 2:
The number 636 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (4) from the dividend to 66 and continue with: 664 / 636

Going ahead to step 3:
If we divide 664 by 636, we get 1 and a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 636 from 664 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 636

Step 4:
281 divided by 636 is 0 with a remainder of 281.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 281, we end up with 281.
Grab the next digit (7) from the dividend, add it to 281, then carry on: 2817 / 636

Advancing to step 5:
636 goes into 2817 4 times with a remainder of 273.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 2544 from 2817 to get 273.
Include the next digit (5) from the dividend after 273, then repeat: 2735 / 636

Going ahead to step 6:
636 goes into 2735 4 times with a remainder of 191.
The number 4 becomes the next digit in our result. 
Result so far: 1044.0
Subtract 2544 from 2735 to get 191.
Grab the next digit (5) from the dividend, add it to 191, then carry on: 1915 / 636

Advancing to step 7:
636 can be fit into 1915 3 times, resulting in a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 10443.0
Deduct 1908 from 1915 and we're left with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 636

Going ahead to step 8:
The number 636 fits into 78 0 times, leaving a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 104430.0
The remainder is 78 after subtracting 0 from 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
780 divided by 636 is 1 with a remainder of 144.
Put 1 as the next digit of the answer. 
Result so far: 104430.1
If we take 636 away from 780, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 10:
The number 636 fits into 1440 2 times, leaving a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 104430.12
If we subtract 1272 from 1440, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 11:
1680 divided by 636 is 2 with a remainder of 408.
Use 2 as the next digit of our solution. 
Result so far: 104430.122
Subtract 1272 from 1680 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

The final outcome is 104430.122, with a leftover of 0.0408.
