386099 ÷ 81 
Our goal is to divide 386099 by 81.

On to step 1:
When dividing 3 by 81, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 81

Going ahead to step 2:
81 can be fit into 38 0 times, resulting in a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 81

Let's proceed to step 3:
If we divide 386 by 81, we get 4 and a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 62 after subtracting 324 from 386.
Bring next digit (0) of the dividend behind the 62 and repeat the process: 620 / 81

Step 4:
81 can be fit into 620 7 times, resulting in a remainder of 53.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 567 from 620 and we're left with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 81

Step 5:
The number 81 fits into 539 6 times, leaving a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 476.0
Deduct 486 from 539 and we're left with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 81

Advancing to step 6:
When dividing 539 by 81, we get 6 with a remainder of 53.
Put 6 as the next digit of the answer. 
Result so far: 4766.0
Subtracting 486 from 539 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
81 goes into 530 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 4766.6
If we subtract 486 from 530, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 8:
If we divide 440 by 81, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4766.65
Subtracting 405 from 440 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
The number 81 fits into 350 4 times, leaving a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 4766.654
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.

Going ahead to step 10:
If we divide 260 by 81, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 4766.6543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
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: 4766.65432
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
If we divide 80 by 81, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4766.65432
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
81 can be fit into 800 9 times, resulting in a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 4766.6543209
If we take 729 away from 800, we end up 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.

Step 14:
When dividing 710 by 81, we get 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 4766.65432098
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.

The final result is 4766.65432098 with a remainder of 6.2e-08.
