64718355 ÷ 591 
We're looking to find how many times 591 goes into 64718355.

Step 1:
591 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 591

Going ahead to step 2:
591 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
Subtracting 0 from 64 leaves us with 64.
Bring next digit (7) of the dividend behind the 64 and repeat the process: 647 / 591

Let's proceed to step 3:
591 can be fit into 647 1 times, resulting in a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 591 away from 647, we end up with 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 591

Advancing to step 4:
When dividing 561 by 591, we get 0 with a remainder of 561.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 561 and we're left with 561.
Bring next digit (8) of the dividend behind the 561 and repeat the process: 5618 / 591

Moving on to step 5:
591 can be fit into 5618 9 times, resulting in a remainder of 299.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
Subtracting 5319 from 5618 leaves us with 299.
Include the next digit (3) from the dividend after 299, then repeat: 2993 / 591

Let's proceed to step 6:
The number 591 fits into 2993 5 times, leaving a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 1095.0
Deduct 2955 from 2993 and we're left with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 591

Going ahead to step 7:
If we divide 385 by 591, we get 0 and a remainder of 385.
Write down 0 as next digit of the result. 
Result so far: 10950.0
Subtract 0 from 385 to get 385.
Bring next digit (5) of the dividend behind the 385 and repeat the process: 3855 / 591

Let's proceed to step 8:
591 can be fit into 3855 6 times, resulting in a remainder of 309.
Write down 6 as next digit of the result. 
Result so far: 109506.0
Subtract 3546 from 3855 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 9:
The number 591 fits into 3090 5 times, leaving a remainder of 135.
Put 5 as the next digit of the answer. 
Result so far: 109506.5
If we take 2955 away from 3090, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 10:
If we divide 1350 by 591, we get 2 and a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 109506.52
Subtract 1182 from 1350 to 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.

Advancing to step 11:
When dividing 1680 by 591, we get 2 with a remainder of 498.
The next digit of our result is 2. 
Result so far: 109506.522
If we take 1182 away from 1680, we end up with 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4980, and continue the process.

After the division, we end up with 109506.522 and a remainder of 0.0498.
