We're dividing 138138 by 81 
Our goal is to divide 138138 by 81.

Advancing to step 1:
81 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 81

On to step 2:
13 divided by 81 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 81

Going ahead to step 3:
The number 81 fits into 138 1 times, leaving a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 81 from 138, we get 57.
Include the next digit (1) from the dividend after 57, then repeat: 571 / 81

Step 4:
81 can be fit into 571 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 567 away from 571, we end up with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 81

Let's proceed to step 5:
43 divided by 81 is 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 170.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 81

Step 6:
The number 81 fits into 438 5 times, leaving a remainder of 33.
The next digit of our result is 5. 
Result so far: 1705.0
Subtracting 405 from 438 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 7:
When dividing 330 by 81, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 1705.4
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
When dividing 60 by 81, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 1705.4
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 81, we get 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 1705.407
If we take 567 away from 600, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
330 divided by 81 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1705.4074
The remainder is 6 after subtracting 324 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
60 divided by 81 is 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1705.4074
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
600 divided by 81 is 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 1705.407407
If we subtract 567 from 600, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 13:
If we divide 330 by 81, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 1705.4074074
Deduct 324 from 330 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
81 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 1705.4074074
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 1705.4074074 with a remaining 6e-08.
