801535 ÷ 64 
Let's see how many times 64 fits into 801535.

On to step 1:
8 divided by 64 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 64

Going ahead to step 2:
If we divide 80 by 64, we get 1 and a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 64 from 80 leaves us with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 64

Let's proceed to step 3:
If we divide 161 by 64, we get 2 and a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 33 after subtracting 128 from 161.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 64

Advancing to step 4:
When dividing 335 by 64, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
The remainder is 15 after subtracting 320 from 335.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 64

Advancing to step 5:
When dividing 153 by 64, we get 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 1252.0
Deduct 128 from 153 and we're left with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 64

On to step 6:
255 divided by 64 is 3 with a remainder of 63.
The next digit of our result is 3. 
Result so far: 12523.0
Subtracting 192 from 255 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
If we divide 630 by 64, we get 9 and a remainder of 54.
The next digit of our result is 9. 
Result so far: 12523.9
The remainder is 54 after subtracting 576 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
When dividing 540 by 64, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 12523.98
If we take 512 away from 540, we end up 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.

Step 9:
If we divide 280 by 64, we get 4 and a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 12523.984
Subtracting 256 from 280 leaves us 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.

Going ahead to step 10:
240 divided by 64 is 3 with a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 12523.9843
Subtracting 192 from 240 leaves us 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.

Step 11:
The number 64 fits into 480 7 times, leaving a remainder of 32.
The next digit of our result is 7. 
Result so far: 12523.98437
If we subtract 448 from 480, 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 can be fit into 320 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12523.984375
Subtract 320 from 320 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.

Step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12523.984375
Subtracting 0 from 0 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.

Advancing to step 14:
64 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12523.984375
The remainder is 0 after subtracting 0 from 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 12523.984375, and the remainder is 0.0.
