424471 divided by 86 
We want to divide 424471 by 86.

Step 1:
4 divided by 86 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 86

Going ahead to step 2:
The number 86 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 86

Going ahead to step 3:
86 goes into 424 4 times with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 344 from 424 and we're left with 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 86

Let's proceed to step 4:
86 goes into 804 9 times with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 774 away from 804, we end up with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 86

Step 5:
If we divide 307 by 86, we get 3 and a remainder of 49.
Write down 3 as next digit of the result. 
Result so far: 493.0
Subtracting 258 from 307 leaves us with 49.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 86

Moving on to step 6:
If we divide 491 by 86, we get 5 and a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 4935.0
If we subtract 430 from 491, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 7:
86 goes into 610 7 times with a remainder of 8.
The next digit of our result is 7. 
Result so far: 4935.7
Deduct 602 from 610 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 86 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4935.7
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
86 goes into 800 9 times with a remainder of 26.
The next digit of our result is 9. 
Result so far: 4935.709
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
When dividing 260 by 86, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 4935.7093
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
20 divided by 86 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4935.7093
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
86 can be fit into 200 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 4935.709302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4935.7093023
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 14:
The number 86 fits into 220 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 4935.70930232
Subtract 172 from 220 to 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.

The final outcome is 4935.70930232, with a leftover of 4.8e-08.
