We divide 344572 by 81
Our goal is to divide 344572 by 81.

Step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 81

On to step 2:
The number 81 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Bring next digit (4) of the dividend behind the 34 and repeat the process: 344 / 81

Going ahead to step 3:
If we divide 344 by 81, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 324 from 344 to get 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 81

Let's proceed to step 4:
When dividing 205 by 81, we get 2 with a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 42.0
Deduct 162 from 205 and we're left with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 81

Moving on to step 5:
437 divided by 81 is 5 with a remainder of 32.
The next digit of our result is 5. 
Result so far: 425.0
Subtract 405 from 437 to get 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 81

Moving on to step 6:
The number 81 fits into 322 3 times, leaving a remainder of 79.
The next digit of our result is 3. 
Result so far: 4253.0
Subtracting 243 from 322 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.

Let's proceed to step 7:
81 goes into 790 9 times with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 4253.9
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 8:
When dividing 610 by 81, we get 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 4253.97
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
430 divided by 81 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4253.975
Subtract 405 from 430 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 4253.9753
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.

On to step 11:
81 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 4253.9753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
If we divide 700 by 81, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 4253.975308
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 13:
The number 81 fits into 520 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 4253.9753086
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 14:
If we divide 340 by 81, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 4253.97530864
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 4253.97530864 with a remaining 1.6e-08.
