We look at the division of 620808 by 81 
We want to figure out the number of times 620808 can be divided by 81.

Moving on to step 1:
81 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 81

Step 2:
62 divided by 81 is 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 81

Let's proceed to step 3:
81 goes into 620 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 53 after subtracting 567 from 620.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 81

On to step 4:
When dividing 538 by 81, we get 6 with a remainder of 52.
The next digit of our result is 6. 
Result so far: 76.0
If we subtract 486 from 538, we get 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 81

Advancing to step 5:
520 divided by 81 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 766.0
Deduct 486 from 520 and we're left with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 81

Moving on to step 6:
348 divided by 81 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 7664.0
The remainder is 24 after subtracting 324 from 348.
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 7:
When dividing 240 by 81, we get 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 7664.2
If we take 162 away from 240, we end up 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.

Step 8:
81 goes into 780 9 times with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 7664.29
If we subtract 729 from 780, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
81 can be fit into 510 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7664.296
Subtracting 486 from 510 leaves us 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.

Moving on to step 10:
The number 81 fits into 240 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 7664.2962
If we take 162 away from 240, we end up 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 11:
If we divide 780 by 81, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 7664.29629
The remainder is 51 after subtracting 729 from 780.
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 12:
510 divided by 81 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 7664.296296
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
81 goes into 240 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 7664.2962962
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.

Moving on to step 14:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The next digit of our result is 9. 
Result so far: 7664.29629629
The remainder is 51 after subtracting 729 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 7664.29629629 with a remaining 5.1e-08.
