We look at the division of 43329373 by 9 
We want to divide 43329373 by 9.

On to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

Let's proceed to step 2:
9 goes into 43 4 times with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 36 away from 43, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 9

Let's proceed to step 3:
73 divided by 9 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 72 from 73 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 9

Step 4:
9 can be fit into 12 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 481.0
Subtracting 9 from 12 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 9

On to step 5:
39 divided by 9 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 4814.0
Subtracting 36 from 39 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 9

Step 6:
9 can be fit into 33 3 times, resulting in a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 48143.0
If we take 27 away from 33, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 9

Let's proceed to step 7:
67 divided by 9 is 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 481437.0
Subtract 63 from 67 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 9

Let's proceed to step 8:
When dividing 43 by 9, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 4814374.0
Deduct 36 from 43 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
9 goes into 70 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 4814374.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
When dividing 70 by 9, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 4814374.77
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 4814374.77 with a remaining 0.007.
