Let's divide 420560 by 64
Let's see how many times 64 fits into 420560.

Going ahead to step 1:
64 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 64

Advancing to step 2:
64 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 64

Going ahead to step 3:
64 can be fit into 420 6 times, resulting in a remainder of 36.
The next digit of our result is 6. 
Result so far: 6.0
If we take 384 away from 420, we end up with 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 64

Going ahead to step 4:
64 goes into 365 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
Subtracting 320 from 365 leaves us with 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 64

Moving on to step 5:
When dividing 456 by 64, we get 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 657.0
The remainder is 8 after subtracting 448 from 456.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 64

Let's proceed to step 6:
64 can be fit into 80 1 times, resulting in a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 6571.0
Subtracting 64 from 80 leaves us 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.

On to step 7:
When dividing 160 by 64, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 6571.2
Deduct 128 from 160 and we're left 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.

Step 8:
When dividing 320 by 64, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6571.25
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 9:
If we divide 0 by 64, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6571.25
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.

Going ahead to step 10:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6571.25
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.

The final outcome is 6571.25, with a leftover of 0.0.
