The number 99 fits into 540 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 869794.5
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
When dividing 450 by 99, we get 4 with a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 869794.54
Subtracting 396 from 450 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 869794.545
Deduct 495 from 540 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 12:
If we divide 450 by 99, we get 4 and a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 869794.5454
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 13:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 869794.54545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 14:
450 divided by 99 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 869794.545454
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 15:
540 divided by 99 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 869794.5454545
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 16:
