Let's divide 581639 by 81
Let's see how many times 81 fits into 581639.

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.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 81

Step 2:
81 can be fit into 58 0 times, resulting in a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Bring next digit (1) of the dividend behind the 58 and repeat the process: 581 / 81

Going ahead to step 3:
The number 81 fits into 581 7 times, leaving a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 567 from 581 and we're left with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 81

Let's proceed to step 4:
81 goes into 146 1 times with a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 81 from 146 and we're left with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 81

Going ahead to step 5:
81 goes into 653 8 times with a remainder of 5.
The next digit of our result is 8. 
Result so far: 718.0
The remainder is 5 after subtracting 648 from 653.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 81

Advancing to step 6:
The number 81 fits into 59 0 times, leaving a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 7180.0
Subtracting 0 from 59 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
81 goes into 590 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 7180.7
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
230 divided by 81 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 7180.72
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
680 divided by 81 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 7180.728
If we take 648 away from 680, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
81 can be fit into 320 3 times, resulting in a remainder of 77.
The number 3 becomes the next digit in our result. 
Result so far: 7180.7283
If we take 243 away from 320, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 11:
81 can be fit into 770 9 times, resulting in a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 7180.72839
Subtracting 729 from 770 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
81 goes into 410 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 7180.728395
The remainder is 5 after subtracting 405 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 81 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 7180.728395
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
When dividing 500 by 81, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 7180.72839506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 7180.72839506 with a remainder of 1.4e-08.
