We look at the division of 380589 by 81 
We want to figure out the number of times 380589 can be divided by 81.

Step 1:
If we divide 3 by 81, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 81

Going ahead to step 2:
If we divide 38 by 81, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Fetch the next digit (0) from the dividend, attach it to 38 and continue: 380 / 81

Moving on to step 3:
The number 81 fits into 380 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 324 from 380 leaves us with 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 81

Step 4:
81 can be fit into 565 6 times, resulting in a remainder of 79.
Put 6 as the next digit of the answer. 
Result so far: 46.0
The remainder is 79 after subtracting 486 from 565.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 81

Going ahead to step 5:
81 can be fit into 798 9 times, resulting in a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 469.0
If we take 729 away from 798, we end up with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 81

Moving on to step 6:
81 goes into 699 8 times with a remainder of 51.
Use 8 as the next digit of our solution. 
Result so far: 4698.0
Subtract 648 from 699 to 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.

Going ahead to step 7:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4698.6
Deduct 486 from 510 and we're left 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.

Let's proceed to step 8:
81 goes into 240 2 times with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 4698.62
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.

Going ahead to step 9:
If we divide 780 by 81, we get 9 and a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 4698.629
If we take 729 away from 780, we end up 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.

Moving on to step 10:
81 goes into 510 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 4698.6296
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.

Let's proceed to step 11:
81 can be fit into 240 2 times, resulting in a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 4698.62962
Subtract 162 from 240 to 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.

Let's proceed to step 12:
81 goes into 780 9 times with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 4698.629629
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.

On to step 13:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 4698.6296296
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.

Advancing to step 14:
81 can be fit into 240 2 times, resulting in a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 4698.62962962
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 4698.62962962 with a remainder of 7.8e-08.
