Let's divide 589638 by 81
We want to figure out the number of times 589638 can be divided by 81.

Let's proceed to step 1:
5 divided by 81 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 81

Going ahead to step 2:
58 divided by 81 is 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 81

Advancing to step 3:
If we divide 589 by 81, we get 7 and a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 567 from 589, we get 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 81

Going ahead to step 4:
The number 81 fits into 226 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 162 from 226, we get 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 81

On to step 5:
The number 81 fits into 643 7 times, leaving a remainder of 76.
Use 7 as the next digit of our solution. 
Result so far: 727.0
The remainder is 76 after subtracting 567 from 643.
Take the next digit (8) from the dividend and append it to 76, then repeat: 768 / 81

Let's proceed to step 6:
When dividing 768 by 81, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 7279.0
If we subtract 729 from 768, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 7:
When dividing 390 by 81, we get 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 7279.4
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 8:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 7279.48
If we take 648 away from 660, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
The number 81 fits into 120 1 times, leaving a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 7279.481
If we take 81 away from 120, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 10:
The number 81 fits into 390 4 times, leaving a remainder of 66.
The next digit of our result is 4. 
Result so far: 7279.4814
If we subtract 324 from 390, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
The number 81 fits into 660 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 7279.48148
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
The number 81 fits into 120 1 times, leaving a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 7279.481481
Subtract 81 from 120 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
390 divided by 81 is 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 7279.4814814
If we take 324 away from 390, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 14:
The number 81 fits into 660 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 7279.48148148
The remainder is 12 after subtracting 648 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 7279.48148148, with a leftover of 1.2e-08.
