We look at the division of 66783628 by 9 
We want to divide 66783628 by 9.

Going ahead to step 1:
When dividing 6 by 9, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 9

On to step 2:
9 can be fit into 66 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 63 from 66, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 9

Step 3:
The number 9 fits into 37 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 74.0
Subtracting 36 from 37 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 9

Let's proceed to step 4:
9 goes into 18 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 742.0
Subtract 18 from 18 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 9

Moving on to step 5:
3 divided by 9 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 7420.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 9

Going ahead to step 6:
9 can be fit into 36 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 74204.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 9

Moving on to step 7:
2 divided by 9 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 742040.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 9

Advancing to step 8:
9 can be fit into 28 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 7420403.0
If we take 27 away from 28, 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.

Advancing to step 9:
The number 9 fits into 10 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 7420403.1
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.

Advancing to step 10:
10 divided by 9 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 7420403.11
Subtracting 9 from 10 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.

The final result is 7420403.11 with a remainder of 0.001.
