Let's divide 604359 by 81
We want to figure out the number of times 604359 can be divided by 81.

Moving on 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
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 81

Advancing to step 2:
When dividing 60 by 81, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 60 leaves us with 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 81

On to step 3:
604 divided by 81 is 7 with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 37 after subtracting 567 from 604.
Bring next digit (3) of the dividend behind the 37 and repeat the process: 373 / 81

Going ahead to step 4:
If we divide 373 by 81, we get 4 and a remainder of 49.
The next digit of our result is 4. 
Result so far: 74.0
If we take 324 away from 373, we end up with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 81

On to step 5:
If we divide 495 by 81, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 746.0
If we subtract 486 from 495, we get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 81

Advancing to step 6:
99 divided by 81 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 7461.0
Deduct 81 from 99 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
81 can be fit into 180 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 7461.2
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
180 divided by 81 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 7461.22
Subtracting 162 from 180 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 7461.22 with a remaining 0.018.
