142455 divided by 86 
Our goal is to divide 142455 by 86.

On to step 1:
86 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 86

Advancing to step 2:
86 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 86

On to step 3:
86 goes into 142 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 86 from 142 to get 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 86

Let's proceed to step 4:
86 can be fit into 564 6 times, resulting in a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 516 from 564 and we're left with 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 86

Let's proceed to step 5:
When dividing 485 by 86, we get 5 with a remainder of 55.
The next digit of our result is 5. 
Result so far: 165.0
Subtract 430 from 485 to get 55.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 86

Advancing to step 6:
When dividing 555 by 86, we get 6 with a remainder of 39.
Write down 6 as next digit of the result. 
Result so far: 1656.0
Subtract 516 from 555 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
86 goes into 390 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 1656.4
Subtract 344 from 390 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 8:
460 divided by 86 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1656.45
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
If we divide 300 by 86, we get 3 and a remainder of 42.
The next digit of our result is 3. 
Result so far: 1656.453
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
When dividing 420 by 86, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 1656.4534
Deduct 344 from 420 and we're left 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.

Moving on to step 11:
86 goes into 760 8 times with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 1656.45348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
If we divide 720 by 86, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 1656.453488
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 1656.453488, and the remainder is 3.2e-06.
