We divide 426255 by 86
We want to figure out the number of times 426255 can be divided by 86.

Moving on to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 86

Let's proceed to step 2:
When dividing 42 by 86, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 86

On to step 3:
86 can be fit into 426 4 times, resulting in a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 344 from 426 to get 82.
Include the next digit (2) from the dividend after 82, then repeat: 822 / 86

Let's proceed to step 4:
822 divided by 86 is 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 49.0
Subtract 774 from 822 to get 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 86

Going ahead to step 5:
The number 86 fits into 485 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 495.0
If we take 430 away from 485, we end up with 55.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 86

Step 6:
555 divided by 86 is 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 4956.0
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:
390 divided by 86 is 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 4956.4
Deduct 344 from 390 and we're left with 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:
When dividing 460 by 86, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 4956.45
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
If we divide 300 by 86, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 4956.453
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
420 divided by 86 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 4956.4534
If we take 344 away from 420, we end up 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 11:
86 goes into 760 8 times with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 4956.45348
Subtract 688 from 760 to 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.

On to step 12:
If we divide 720 by 86, we get 8 and a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 4956.453488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 4956.453488, with a leftover of 3.2e-06.
