Let's divide 12455 by 86
We want to figure out the number of times 12455 can be divided by 86.

Let's proceed to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 86

On to step 2:
86 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 86

Step 3:
The number 86 fits into 124 1 times, leaving a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 38 after subtracting 86 from 124.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 86

Moving on to step 4:
86 goes into 385 4 times with a remainder of 41.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 344 from 385 to get 41.
Grab the next digit (5) from the dividend, add it to 41, then carry on: 415 / 86

Going ahead to step 5:
415 divided by 86 is 4 with a remainder of 71.
Record the quotient 4 as the next digit in the result. 
Result so far: 144.0
If we take 344 away from 415, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 6:
If we divide 710 by 86, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 144.8
The remainder is 22 after subtracting 688 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 86 fits into 220 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 144.82
If we subtract 172 from 220, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
If we divide 480 by 86, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 144.825
Subtract 430 from 480 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
500 divided by 86 is 5 with a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 144.8255
Subtracting 430 from 500 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

In conclusion, the division gives 144.8255 with a balance of 0.0007.
