We're dividing 39212 by 81 
Let's see how many times 81 fits into 39212.

Advancing to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 81

Let's proceed to step 2:
81 goes into 39 0 times with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 81

Let's proceed to step 3:
81 goes into 392 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 324 from 392 leaves us with 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 81

Let's proceed to step 4:
The number 81 fits into 681 8 times, leaving a remainder of 33.
The next digit of our result is 8. 
Result so far: 48.0
If we take 648 away from 681, we end up with 33.
Grab the next digit (2) from the dividend, add it to 33, then carry on: 332 / 81

Advancing to step 5:
The number 81 fits into 332 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
Subtract 324 from 332 to 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.

Step 6:
When dividing 80 by 81, we get 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 484.0
Deduct 0 from 80 and we're left 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.

Let's proceed to step 7:
The number 81 fits into 800 9 times, leaving a remainder of 71.
The next digit of our result is 9. 
Result so far: 484.09
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 8:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 484.098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 484.0987
Subtracting 567 from 620 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.

Let's proceed to step 10:
When dividing 530 by 81, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 484.09876
If we take 486 away from 530, we end up 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 11:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 484.098765
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.

Moving on to step 12:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 484.0987654
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 13:
The number 81 fits into 260 3 times, leaving a remainder of 17.
The next digit of our result is 3. 
Result so far: 484.09876543
If we take 243 away from 260, we end up 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.

The final outcome is 484.09876543, with a leftover of 1.7e-08.
