Let's divide 132389 by 86
We're looking to find how many times 86 goes into 132389.

Step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 86

Step 2:
The number 86 fits into 13 0 times, leaving 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 (2) from the dividend after 13, then repeat: 132 / 86

Step 3:
When dividing 132 by 86, we get 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 86 from 132 and we're left with 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 86

Advancing to step 4:
463 divided by 86 is 5 with a remainder of 33.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 430 away from 463, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 86

Going ahead to step 5:
86 goes into 338 3 times with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 153.0
Subtracting 258 from 338 leaves us with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 86

On to step 6:
809 divided by 86 is 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 1539.0
Deduct 774 from 809 and we're left 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 7:
If we divide 350 by 86, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 1539.4
If we subtract 344 from 350, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
The number 86 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1539.4
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.

Going ahead to step 9:
When dividing 600 by 86, we get 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 1539.406
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
When dividing 840 by 86, we get 9 with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 1539.4069
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
660 divided by 86 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 1539.40697
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 12:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1539.406976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 13:
640 divided by 86 is 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 1539.4069767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 1539.40697674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 1539.40697674 with a remainder of 3.6e-08.
