We're dividing 168386 by 40 
Our goal is to divide 168386 by 40.

Moving on to step 1:
40 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 40

Let's proceed to step 2:
40 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 40

Let's proceed to step 3:
The number 40 fits into 168 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 160 from 168 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 40

Step 4:
The number 40 fits into 83 2 times, leaving a remainder of 3.
The next digit of our result is 2. 
Result so far: 42.0
If we take 80 away from 83, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 40

Advancing to step 5:
If we divide 38 by 40, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 420.0
Subtract 0 from 38 to get 38.
Grab the next digit (6) from the dividend, add it to 38, then carry on: 386 / 40

Step 6:
386 divided by 40 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 4209.0
If we subtract 360 from 386, 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.

On to step 7:
260 divided by 40 is 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 4209.6
Deduct 240 from 260 and we're left 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.

Going ahead to step 8:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4209.65
Deduct 200 from 200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4209.65
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 40 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4209.65
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 4209.65 and a remainder of 0.0.
