We look at the division of 666586 by 64 
We want to figure out the number of times 666586 can be divided by 64.

Step 1:
When dividing 6 by 64, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 64

On to step 2:
When dividing 66 by 64, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 64 from 66 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 64

On to step 3:
The number 64 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 26 leaves us with 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 64

Let's proceed to step 4:
265 divided by 64 is 4 with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we take 256 away from 265, we end up with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 64

Moving on to step 5:
When dividing 98 by 64, we get 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1041.0
If we subtract 64 from 98, we get 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 64

Going ahead to step 6:
64 goes into 346 5 times with a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 10415.0
Subtracting 320 from 346 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
If we divide 260 by 64, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 10415.4
Subtract 256 from 260 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
When dividing 40 by 64, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10415.4
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
64 can be fit into 400 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 10415.406
The remainder is 16 after subtracting 384 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 64 fits into 160 2 times, leaving a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10415.4062
Subtract 128 from 160 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10415.40625
Deduct 320 from 320 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10415.40625
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 13:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10415.40625
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 10415.40625, and the remainder is 0.0.
