We look at the division of 368508 by 86 
Our goal is to divide 368508 by 86.

Step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 86

Let's proceed to step 2:
86 can be fit into 36 0 times, resulting in a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 86

On to step 3:
When dividing 368 by 86, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 344 from 368 to get 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 86

Going ahead to step 4:
The number 86 fits into 245 2 times, leaving a remainder of 73.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 172 from 245, we get 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 86

Step 5:
If we divide 730 by 86, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 428.0
Subtract 688 from 730 to get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 86

Advancing to step 6:
86 can be fit into 428 4 times, resulting in a remainder of 84.
The next digit of our result is 4. 
Result so far: 4284.0
Subtract 344 from 428 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 7:
86 goes into 840 9 times with a remainder of 66.
The next digit of our result is 9. 
Result so far: 4284.9
Subtract 774 from 840 to 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.

On to step 8:
When dividing 660 by 86, we get 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 4284.97
Subtract 602 from 660 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
When dividing 580 by 86, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 4284.976
If we subtract 516 from 580, we get 64.
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 10:
86 goes into 640 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 4284.9767
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.

Let's proceed to step 11:
If we divide 380 by 86, we get 4 and a remainder of 36.
The next digit of our result is 4. 
Result so far: 4284.97674
The remainder is 36 after subtracting 344 from 380.
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 12:
If we divide 360 by 86, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 4284.976744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 4284.976744 and a remainder of 1.6e-06.
