We look at the division of 673923 by 64 
Let's see how many times 64 fits into 673923.

On to step 1:
64 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 64

Let's proceed to step 2:
If we divide 67 by 64, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 64 from 67 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 64

Let's proceed to step 3:
64 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 33, we get 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 64

Going ahead to step 4:
The number 64 fits into 339 5 times, leaving a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtracting 320 from 339 leaves us with 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 64

Advancing to step 5:
If we divide 192 by 64, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1053.0
The remainder is 0 after subtracting 192 from 192.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 64

On to step 6:
64 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 10530.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 64, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10530.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 64, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 10530.04
Subtracting 256 from 300 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
If we divide 440 by 64, we get 6 and a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 10530.046
Deduct 384 from 440 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
560 divided by 64 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 10530.0468
If we take 512 away from 560, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
If we divide 480 by 64, we get 7 and a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 10530.04687
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.

On to step 12:
When dividing 320 by 64, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 10530.046875
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:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10530.046875
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.

On to step 14:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10530.046875
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 quotient of the division is 10530.046875, and the remainder is 0.0.
