253358 divided by 81 
We want to figure out the number of times 253358 can be divided by 81.

Moving on to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 81

Moving on to step 2:
81 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 81

Step 3:
81 can be fit into 253 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 243 from 253 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 81

Going ahead to step 4:
The number 81 fits into 103 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 31.0
If we take 81 away from 103, we end up with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 81

Step 5:
The number 81 fits into 225 2 times, leaving a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 312.0
The remainder is 63 after subtracting 162 from 225.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 81

On to step 6:
The number 81 fits into 638 7 times, leaving a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 3127.0
Deduct 567 from 638 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
710 divided by 81 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 3127.8
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 8:
620 divided by 81 is 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 3127.87
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
530 divided by 81 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3127.876
Subtracting 486 from 530 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
81 goes into 440 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 3127.8765
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.

Advancing to step 11:
If we divide 350 by 81, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 3127.87654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
When dividing 260 by 81, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3127.876543
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
If we divide 170 by 81, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3127.8765432
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
If we divide 80 by 81, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 3127.8765432
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 3127.8765432 with a remaining 8e-08.
