397285 ÷ 81 
Our goal is to divide 397285 by 81.

Let's proceed to step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 81

Going ahead to step 2:
39 divided by 81 is 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 81

Going ahead to step 3:
81 goes into 397 4 times with a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 324 from 397 to get 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 81

Going ahead to step 4:
81 goes into 732 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 49.0
Subtracting 729 from 732 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 81

On to step 5:
81 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 490.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 81

Advancing to step 6:
If we divide 385 by 81, we get 4 and a remainder of 61.
Record the quotient 4 as the next digit in the result. 
Result so far: 4904.0
The remainder is 61 after subtracting 324 from 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 7:
81 goes into 610 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 4904.7
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 8:
81 goes into 430 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 4904.75
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
81 goes into 250 3 times with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 4904.753
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
81 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 4904.753
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
The number 81 fits into 700 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 4904.75308
If we take 648 away from 700, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
81 can be fit into 520 6 times, resulting in a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 4904.753086
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
81 can be fit into 340 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 4904.7530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
160 divided by 81 is 1 with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 4904.75308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final result is 4904.75308641 with a remainder of 7.9e-08.
