64500544 ÷ 50 
We're looking to find how many times 50 goes into 64500544.

Advancing to step 1:
If we divide 6 by 50, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 50

On to step 2:
The number 50 fits into 64 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 50 from 64 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 50

Moving on to step 3:
145 divided by 50 is 2 with a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 100 from 145, we get 45.
Bring next digit (0) of the dividend behind the 45 and repeat the process: 450 / 50

Moving on to step 4:
When dividing 450 by 50, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtracting 450 from 450 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 50

Step 5:
When dividing 0 by 50, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1290.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 50

Going ahead to step 6:
When dividing 5 by 50, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 12900.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 50

Let's proceed to step 7:
50 goes into 54 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 129001.0
Subtract 50 from 54 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 50

Advancing to step 8:
The number 50 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 1290010.0
Subtracting 0 from 44 leaves us 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.

Moving on to step 9:
If we divide 440 by 50, we get 8 and a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1290010.8
The remainder is 40 after subtracting 400 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 50 fits into 400 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1290010.88
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1290010.88 and a remainder of 0.0.
