We're dividing 670690 by 64 
Let's see how many times 64 fits into 670690.

Moving on to step 1:
If we divide 6 by 64, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 64

On to step 2:
The number 64 fits into 67 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 3 after subtracting 64 from 67.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 64

Let's proceed to step 3:
The number 64 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 64

Going ahead to step 4:
The number 64 fits into 306 4 times, leaving a remainder of 50.
The next digit of our result is 4. 
Result so far: 104.0
Deduct 256 from 306 and we're left with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 64

Advancing to step 5:
509 divided by 64 is 7 with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 1047.0
Subtract 448 from 509 to get 61.
Include the next digit (0) from the dividend after 61, then repeat: 610 / 64

Step 6:
64 goes into 610 9 times with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 10479.0
The remainder is 34 after subtracting 576 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
The number 64 fits into 340 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10479.5
Subtract 320 from 340 to get 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 8:
64 goes into 200 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 10479.53
Subtract 192 from 200 to 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.

Let's proceed to step 9:
64 can be fit into 80 1 times, resulting in a remainder of 16.
The next digit of our result is 1. 
Result so far: 10479.531
Subtract 64 from 80 to 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.

Going ahead to step 10:
64 goes into 160 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10479.5312
Subtract 128 from 160 to 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.

Going ahead to step 11:
The number 64 fits into 320 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 10479.53125
Subtract 320 from 320 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.

Moving on to step 12:
When dividing 0 by 64, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10479.53125
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.

Let's proceed to step 13:
If we divide 0 by 64, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10479.53125
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 quotient of the division is 10479.53125, and the remainder is 0.0.
