420573 ÷ 64 
Our goal is to divide 420573 by 64.

Moving on to step 1:
If we divide 4 by 64, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 64

Advancing to step 2:
The number 64 fits into 42 0 times, leaving a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 64

Step 3:
When dividing 420 by 64, we get 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 384 from 420, we get 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 64

Advancing to step 4:
365 divided by 64 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 65.0
If we take 320 away from 365, we end up with 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 64

On to step 5:
When dividing 457 by 64, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 657.0
Subtracting 448 from 457 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 64

Let's proceed to step 6:
The number 64 fits into 93 1 times, leaving a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 6571.0
Subtract 64 from 93 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
If we divide 290 by 64, we get 4 and a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 6571.4
Deduct 256 from 290 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
If we divide 340 by 64, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 6571.45
If we take 320 away from 340, we end up 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.

Advancing to step 9:
200 divided by 64 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 6571.453
If we subtract 192 from 200, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 64, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 6571.4531
If we subtract 64 from 80, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 6571.45312
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.

Let's proceed to step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6571.453125
If we subtract 320 from 320, 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.

Advancing to step 13:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6571.453125
Deduct 0 from 0 and we're left 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.

Going ahead to step 14:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6571.453125
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 6571.453125, with a leftover of 0.0.
