Let's divide 604394 by 81
We want to figure out the number of times 604394 can be divided by 81.

Advancing to step 1:
81 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 81

Advancing to step 2:
If we divide 60 by 81, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 81

Going ahead to step 3:
81 can be fit into 604 7 times, resulting in a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 37 after subtracting 567 from 604.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 81

Let's proceed to step 4:
When dividing 373 by 81, we get 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 74.0
The remainder is 49 after subtracting 324 from 373.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 81

Let's proceed to step 5:
499 divided by 81 is 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 746.0
Subtracting 486 from 499 leaves us with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 81

Going ahead to step 6:
The number 81 fits into 134 1 times, leaving a remainder of 53.
Write down 1 as next digit of the result. 
Result so far: 7461.0
If we take 81 away from 134, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
81 goes into 530 6 times with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 7461.6
If we subtract 486 from 530, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
440 divided by 81 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 7461.65
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
81 goes into 350 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 7461.654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 81 is 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 7461.6543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 11:
170 divided by 81 is 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 7461.65432
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
80 divided by 81 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 7461.65432
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 13:
81 goes into 800 9 times with a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 7461.6543209
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 14:
710 divided by 81 is 8 with a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 7461.65432098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 7461.65432098 with a remainder of 6.2e-08.
