We look at the division of 605040 by 81 
We want to divide 605040 by 81.

On to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 81

Advancing to step 2:
If we divide 60 by 81, we get 0 and a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 60, we end up with 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 81

Advancing to step 3:
81 goes into 605 7 times with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 38 after subtracting 567 from 605.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 81

Advancing to step 4:
81 can be fit into 380 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we subtract 324 from 380, we get 56.
Fetch the next digit (4) from the dividend, attach it to 56 and continue: 564 / 81

Step 5:
564 divided by 81 is 6 with a remainder of 78.
The number 6 becomes the next digit in our result. 
Result so far: 746.0
Subtracting 486 from 564 leaves us with 78.
Bring next digit (0) of the dividend behind the 78 and repeat the process: 780 / 81

Going ahead to step 6:
The number 81 fits into 780 9 times, leaving a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 7469.0
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
81 goes into 510 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7469.6
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
81 can be fit into 240 2 times, resulting in a remainder of 78.
The next digit of our result is 2. 
Result so far: 7469.62
Subtracting 162 from 240 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 9:
When dividing 780 by 81, we get 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 7469.629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
81 goes into 510 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7469.6296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
81 goes into 240 2 times with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 7469.62962
Deduct 162 from 240 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 12:
81 goes into 780 9 times with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 7469.629629
Subtracting 729 from 780 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 13:
510 divided by 81 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7469.6296296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
81 can be fit into 240 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 7469.62962962
If we subtract 162 from 240, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 7469.62962962 with a remaining 7.8e-08.
