408423 divided by 64 
We want to divide 408423 by 64.

Step 1:
When dividing 4 by 64, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 64

Moving on to step 2:
64 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 64

Going ahead to step 3:
64 goes into 408 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 384 from 408 to get 24.
Bring next digit (4) of the dividend behind the 24 and repeat the process: 244 / 64

Step 4:
244 divided by 64 is 3 with a remainder of 52.
Use 3 as the next digit of our solution. 
Result so far: 63.0
If we subtract 192 from 244, we get 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 64

Let's proceed to step 5:
64 can be fit into 522 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 638.0
If we subtract 512 from 522, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 64

Let's proceed to step 6:
64 can be fit into 103 1 times, resulting in a remainder of 39.
The next digit of our result is 1. 
Result so far: 6381.0
If we subtract 64 from 103, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
The number 64 fits into 390 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6381.6
Subtract 384 from 390 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
60 divided by 64 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 6381.6
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
When dividing 600 by 64, we get 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 6381.609
Subtracting 576 from 600 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.

Moving on to step 10:
64 can be fit into 240 3 times, resulting in a remainder of 48.
The next digit of our result is 3. 
Result so far: 6381.6093
Subtract 192 from 240 to get 48.
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:
480 divided by 64 is 7 with a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 6381.60937
The remainder is 32 after subtracting 448 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
64 goes into 320 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6381.609375
Deduct 320 from 320 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.

Step 13:
64 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6381.609375
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.

Going ahead to step 14:
When dividing 0 by 64, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6381.609375
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.

The quotient of the division is 6381.609375, and the remainder is 0.0.
