418009 ÷ 86 
Let's see how many times 86 fits into 418009.

Step 1:
When dividing 4 by 86, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 86

Let's proceed to step 2:
When dividing 41 by 86, we get 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 86

Moving on to step 3:
418 divided by 86 is 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 74 after subtracting 344 from 418.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 86

Advancing to step 4:
86 can be fit into 740 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we subtract 688 from 740, we get 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 86

Step 5:
If we divide 520 by 86, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 486.0
The remainder is 4 after subtracting 516 from 520.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 86

Step 6:
86 can be fit into 49 0 times, resulting in a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 4860.0
Subtract 0 from 49 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
490 divided by 86 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4860.5
The remainder is 60 after subtracting 430 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
86 goes into 600 6 times with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 4860.56
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 9:
When dividing 840 by 86, we get 9 with a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 4860.569
If we subtract 774 from 840, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
When dividing 660 by 86, we get 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 4860.5697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 4860.56976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
86 can be fit into 640 7 times, resulting in a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 4860.569767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
The number 86 fits into 380 4 times, leaving a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 4860.5697674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 14:
360 divided by 86 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4860.56976744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 4860.56976744, with a leftover of 1.6e-08.
