561891 ÷ 64 
Let's see how many times 64 fits into 561891.

Going ahead to step 1:
64 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 64

Advancing to step 2:
64 goes into 56 0 times with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 56 after subtracting 0 from 56.
Grab the next digit (1) from the dividend, add it to 56, then carry on: 561 / 64

Moving on to step 3:
561 divided by 64 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 512 from 561, we get 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 64

Moving on to step 4:
498 divided by 64 is 7 with a remainder of 50.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 448 away from 498, we end up with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 64

Moving on to step 5:
The number 64 fits into 509 7 times, leaving a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 877.0
Deduct 448 from 509 and we're left with 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 64

On to step 6:
611 divided by 64 is 9 with a remainder of 35.
The next digit of our result is 9. 
Result so far: 8779.0
Subtracting 576 from 611 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 7:
64 can be fit into 350 5 times, resulting in a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8779.5
Subtracting 320 from 350 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 64 fits into 300 4 times, leaving a remainder of 44.
The next digit of our result is 4. 
Result so far: 8779.54
The remainder is 44 after subtracting 256 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
64 can be fit into 440 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 8779.546
Subtract 384 from 440 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
The number 64 fits into 560 8 times, leaving a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 8779.5468
The remainder is 48 after subtracting 512 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to 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: 8779.54687
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.

Advancing to step 12:
320 divided by 64 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8779.546875
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.

Going ahead to step 13:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8779.546875
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.

On to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8779.546875
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.

After the division, we end up with 8779.546875 and a remainder of 0.0.
