We divide 646993 by 9
Our goal is to divide 646993 by 9.

Step 1:
9 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 9

Let's proceed to step 2:
9 can be fit into 64 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 63 away from 64, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 9

Going ahead to step 3:
16 divided by 9 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we take 9 away from 16, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 9

On to step 4:
The number 9 fits into 79 8 times, leaving a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 718.0
Subtracting 72 from 79 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 9

Moving on to step 5:
9 can be fit into 79 8 times, resulting in a remainder of 7.
The number 8 becomes the next digit in our result. 
Result so far: 7188.0
Subtracting 72 from 79 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 9

Advancing to step 6:
73 divided by 9 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 71888.0
Subtracting 72 from 73 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
If we divide 10 by 9, we get 1 and a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 71888.1
If we take 9 away from 10, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
If we divide 10 by 9, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 71888.11
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 71888.11, and the remainder is 0.001.
