660573 divided by 64 
We want to figure out the number of times 660573 can be divided by 64.

Step 1:
64 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
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 64

Going ahead to step 2:
If we divide 66 by 64, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 64 from 66 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 64

Step 3:
When dividing 20 by 64, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 20 to get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 64

Step 4:
The number 64 fits into 205 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Subtract 192 from 205 to get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 64

Advancing to step 5:
64 goes into 137 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 1032.0
Deduct 128 from 137 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 64

Going ahead to step 6:
64 can be fit into 93 1 times, resulting in a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 10321.0
Subtract 64 from 93 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
290 divided by 64 is 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 10321.4
If we take 256 away from 290, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
64 goes into 340 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10321.45
Subtracting 320 from 340 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 64, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 10321.453
Subtracting 192 from 200 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
64 can be fit into 80 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 10321.4531
If we subtract 64 from 80, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
When dividing 160 by 64, we get 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10321.45312
If we subtract 128 from 160, we 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.

Step 12:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 10321.453125
Subtracting 320 from 320 leaves us 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.

On to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10321.453125
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.

On to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10321.453125
Deduct 0 from 0 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.

Our division results in 10321.453125 with a remaining 0.0.
