39139013 divided by 81 
Our goal is to divide 39139013 by 81.

Moving on to step 1:
If we divide 3 by 81, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 81

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 (1) from the dividend after 39, then repeat: 391 / 81

Step 3:
If we divide 391 by 81, we get 4 and a remainder of 67.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 324 from 391, we get 67.
Bring next digit (3) of the dividend behind the 67 and repeat the process: 673 / 81

Let's proceed to step 4:
If we divide 673 by 81, we get 8 and a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 48.0
Subtracting 648 from 673 leaves us with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 81

On to step 5:
259 divided by 81 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 483.0
Subtracting 243 from 259 leaves us with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 81

Advancing to step 6:
160 divided by 81 is 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 4831.0
Deduct 81 from 160 and we're left with 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 81

Moving on to step 7:
When dividing 791 by 81, we get 9 with a remainder of 62.
Record the quotient 9 as the next digit in the result. 
Result so far: 48319.0
If we take 729 away from 791, we end up with 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 81

Advancing to step 8:
The number 81 fits into 623 7 times, leaving a remainder of 56.
Record the quotient 7 as the next digit in the result. 
Result so far: 483197.0
Subtracting 567 from 623 leaves us with 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 9:
When dividing 560 by 81, we get 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 483197.6
The remainder is 74 after subtracting 486 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 10:
740 divided by 81 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 483197.69
The remainder is 11 after subtracting 729 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
When dividing 110 by 81, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 483197.691
If we subtract 81 from 110, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 12:
81 goes into 290 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 483197.6913
Deduct 243 from 290 and we're left with 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 13:
When dividing 470 by 81, we get 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 483197.69135
Subtracting 405 from 470 leaves us 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.

Step 14:
650 divided by 81 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 483197.691358
If we subtract 648 from 650, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 15:
20 divided by 81 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 483197.691358
If we take 0 away from 20, we end up 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.

Step 16:
81 goes into 200 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 483197.69135802
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 483197.69135802 with a balance of 3.8e-08.
