551457 ÷ 81 
Let's see how many times 81 fits into 551457.

Let's proceed to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 81

On to step 2:
The number 81 fits into 55 0 times, leaving a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 81

Advancing to step 3:
81 goes into 551 6 times with a remainder of 65.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 486 from 551 leaves us with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 81

Going ahead to step 4:
The number 81 fits into 654 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we take 648 away from 654, we end up with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 81

Let's proceed to step 5:
81 goes into 65 0 times with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 680.0
If we take 0 away from 65, we end up with 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 81

Advancing to step 6:
657 divided by 81 is 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 6808.0
The remainder is 9 after subtracting 648 from 657.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
The number 81 fits into 90 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 6808.1
Subtracting 81 from 90 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
81 goes into 90 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 6808.11
If we take 81 away from 90, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 6808.11 with a balance of 0.009.
