We're dividing 425 by 86 
Let's see how many times 86 fits into 425.

Going ahead to step 1:
86 goes into 4 0 times with 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.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 86

On to step 2:
The number 86 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 86

Going ahead to step 3:
The number 86 fits into 425 4 times, leaving a remainder of 81.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 81 after subtracting 344 from 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 4:
When dividing 810 by 86, we get 9 with a remainder of 36.
The next digit of our result is 9. 
Result so far: 4.9
The remainder is 36 after subtracting 774 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 5:
If we divide 360 by 86, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 4.94
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 6:
86 can be fit into 160 1 times, resulting in a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 4.941
If we take 86 away from 160, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 7:
740 divided by 86 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 4.9418
Subtract 688 from 740 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
When dividing 520 by 86, we get 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 4.94186
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
86 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4.94186
Subtracting 0 from 40 leaves us with 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 10:
400 divided by 86 is 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 4.9418604
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
When dividing 560 by 86, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4.94186046
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final result is 4.94186046 with a remainder of 4.4e-08.
