We look at the division of 673638 by 64 
Our goal is to divide 673638 by 64.

Step 1:
64 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 64

Moving on to step 2:
The number 64 fits into 67 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 64 from 67 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 64

Let's proceed to step 3:
64 goes into 33 0 times with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 33 and we're left with 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 64

Going ahead to step 4:
When dividing 336 by 64, we get 5 with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
Subtract 320 from 336 to get 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 64

Going ahead to step 5:
If we divide 163 by 64, we get 2 and a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 1052.0
Subtracting 128 from 163 leaves us with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 64

Let's proceed to step 6:
358 divided by 64 is 5 with a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 10525.0
If we take 320 away from 358, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
380 divided by 64 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 10525.5
If we take 320 away from 380, we end up 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.

Going ahead to step 8:
The number 64 fits into 600 9 times, leaving a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 10525.59
Subtract 576 from 600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 64 is 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 10525.593
If we take 192 away from 240, 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.

Step 10:
If we divide 480 by 64, we get 7 and a remainder of 32.
Put 7 as the next digit of the answer. 
Result so far: 10525.5937
If we take 448 away from 480, 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.

Step 11:
320 divided by 64 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10525.59375
If we take 320 away from 320, 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.

Let's proceed to step 12:
The number 64 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10525.59375
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.

Moving on to step 13:
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: 10525.59375
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 10525.59375, with a leftover of 0.0.
