We look at the division of 387118 by 86 
Our goal is to divide 387118 by 86.

Advancing to step 1:
3 divided by 86 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 86

Step 2:
86 goes into 38 0 times with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Fetch the next digit (7) from the dividend, attach it to 38 and continue: 387 / 86

Let's proceed to step 3:
86 can be fit into 387 4 times, resulting in a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 344 from 387 and we're left with 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 86

Step 4:
The number 86 fits into 431 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 45.0
If we take 430 away from 431, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 86

Let's proceed to step 5:
When dividing 11 by 86, we get 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
Deduct 0 from 11 and we're left with 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 86

Step 6:
The number 86 fits into 118 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 4501.0
Subtract 86 from 118 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
If we divide 320 by 86, we get 3 and a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 4501.3
Subtract 258 from 320 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 86, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 4501.37
The remainder is 18 after subtracting 602 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 86, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 4501.372
The remainder is 8 after subtracting 172 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
The number 86 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 4501.372
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
When dividing 800 by 86, we get 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 4501.37209
If we subtract 774 from 800, we 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.

Moving on to step 12:
86 can be fit into 260 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 4501.372093
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
When dividing 20 by 86, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4501.372093
If we take 0 away from 20, we end up 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.

Let's proceed to step 14:
86 goes into 200 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4501.37209302
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.

After the division, we end up with 4501.37209302 and a remainder of 2.8e-08.
