We divide 139864 by 81
We're looking to find how many times 81 goes into 139864.

Going ahead to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 81

Step 2:
13 divided by 81 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 81

Step 3:
139 divided by 81 is 1 with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 81 from 139 leaves us with 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 81

Step 4:
When dividing 588 by 81, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 567 from 588 and we're left with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 81

Advancing to step 5:
216 divided by 81 is 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 172.0
If we take 162 away from 216, we end up with 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 81

Moving on to step 6:
81 can be fit into 544 6 times, resulting in a remainder of 58.
Put 6 as the next digit of the answer. 
Result so far: 1726.0
If we subtract 486 from 544, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
If we divide 580 by 81, we get 7 and a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 1726.7
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
The number 81 fits into 130 1 times, leaving a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1726.71
Subtract 81 from 130 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
When dividing 490 by 81, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1726.716
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
40 divided by 81 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1726.716
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
If we divide 400 by 81, we get 4 and a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 1726.71604
Subtracting 324 from 400 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
81 goes into 760 9 times with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 1726.716049
If we subtract 729 from 760, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
81 goes into 310 3 times with a remainder of 67.
Use 3 as the next digit of our solution. 
Result so far: 1726.7160493
If we take 243 away from 310, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 14:
When dividing 670 by 81, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 1726.71604938
If we take 648 away from 670, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 1726.71604938, with a leftover of 2.2e-08.
