We divide 355592 by 81
Our goal is to divide 355592 by 81.

On to step 1:
81 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 81

Advancing to step 2:
35 divided by 81 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 81

Step 3:
355 divided by 81 is 4 with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 324 from 355, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 81

Let's proceed to step 4:
When dividing 315 by 81, we get 3 with a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
The remainder is 72 after subtracting 243 from 315.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 81

On to step 5:
If we divide 729 by 81, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 439.0
Subtracting 729 from 729 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 81

Advancing to step 6:
81 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 4390.0
If we take 0 away from 2, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
81 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4390.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
81 goes into 200 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 4390.02
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
81 can be fit into 380 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 4390.024
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
If we divide 560 by 81, we get 6 and a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 4390.0246
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
740 divided by 81 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 4390.02469
If we take 729 away from 740, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
The number 81 fits into 110 1 times, leaving a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 4390.024691
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
81 goes into 290 3 times with a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 4390.0246913
If we subtract 243 from 290, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 14:
81 goes into 470 5 times with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 4390.02469135
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final result is 4390.02469135 with a remainder of 6.5e-08.
