We look at the division of 599838 by 81 
Let's see how many times 81 fits into 599838.

Going ahead to step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 81

Moving on to step 2:
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: 0.0
The remainder is 59 after subtracting 0 from 59.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 81

On to step 3:
81 goes into 599 7 times with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 567 from 599 leaves us with 32.
Include the next digit (8) from the dividend after 32, then repeat: 328 / 81

Going ahead to step 4:
328 divided by 81 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
The remainder is 4 after subtracting 324 from 328.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 81

Step 5:
If we divide 43 by 81, we get 0 and a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 740.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 81

On to step 6:
438 divided by 81 is 5 with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 7405.0
If we take 405 away from 438, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
If we divide 330 by 81, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 7405.4
Subtracting 324 from 330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 81, we get 0 and a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7405.4
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
600 divided by 81 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 7405.407
Subtract 567 from 600 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
If we divide 330 by 81, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 7405.4074
Subtracting 324 from 330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
When dividing 60 by 81, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7405.4074
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
600 divided by 81 is 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 7405.407407
Deduct 567 from 600 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
330 divided by 81 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 7405.4074074
Deduct 324 from 330 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
The number 81 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 7405.4074074
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 7405.4074074 with a remainder of 6e-08.
