We're dividing 645759 by 64 
Our goal is to divide 645759 by 64.

Let's proceed to 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
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 64

On to step 2:
When dividing 64 by 64, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 64 from 64 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 64

Let's proceed to step 3:
If we divide 5 by 64, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 64

Let's proceed to step 4:
57 divided by 64 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 57 after subtracting 0 from 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 64

Step 5:
575 divided by 64 is 8 with a remainder of 63.
The next digit of our result is 8. 
Result so far: 1008.0
If we take 512 away from 575, we end up with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 64

Advancing to step 6:
If we divide 639 by 64, we get 9 and a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 10089.0
Subtract 576 from 639 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 7:
630 divided by 64 is 9 with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 10089.9
Subtract 576 from 630 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
When dividing 540 by 64, we get 8 with a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 10089.98
Deduct 512 from 540 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 64, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 10089.984
If we take 256 away from 280, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
The number 64 fits into 240 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 10089.9843
Deduct 192 from 240 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
480 divided by 64 is 7 with a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 10089.98437
Subtract 448 from 480 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.

Moving on to step 12:
64 goes into 320 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10089.984375
If we take 320 away from 320, 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.

Moving on to step 13:
64 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 10089.984375
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.

Moving on to step 14:
0 divided by 64 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10089.984375
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.

The final outcome is 10089.984375, with a leftover of 0.0.
