We look at the division of 561901 by 64 
We want to figure out the number of times 561901 can be divided by 64.

Moving on to step 1:
64 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 64

Going ahead to step 2:
If we divide 56 by 64, we get 0 and a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 64

Going ahead to step 3:
561 divided by 64 is 8 with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 512 from 561 and we're left with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 64

Let's proceed to step 4:
When dividing 499 by 64, we get 7 with a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we take 448 away from 499, we end up with 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 64

Going ahead to step 5:
If we divide 510 by 64, we get 7 and a remainder of 62.
Write down 7 as next digit of the result. 
Result so far: 877.0
If we subtract 448 from 510, we get 62.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 64

On to step 6:
The number 64 fits into 621 9 times, leaving a remainder of 45.
Record the quotient 9 as the next digit in the result. 
Result so far: 8779.0
If we take 576 away from 621, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
When dividing 450 by 64, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 8779.7
The remainder is 2 after subtracting 448 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
64 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8779.7
Deduct 0 from 20 and we're left 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.

Let's proceed to step 9:
200 divided by 64 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 8779.703
The remainder is 8 after subtracting 192 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
If we divide 80 by 64, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 8779.7031
Deduct 64 from 80 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 64 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 8779.70312
If we take 128 away from 160, we end up with 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:
320 divided by 64 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8779.703125
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: 8779.703125
If we subtract 0 from 0, we 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.

Let's proceed to step 14:
0 divided by 64 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8779.703125
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.

The final outcome is 8779.703125, with a leftover of 0.0.
