We're dividing 134286 by 40 
We want to figure out the number of times 134286 can be divided by 40.

Let's proceed to step 1:
40 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 40

Step 2:
When dividing 13 by 40, we get 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 40

Going ahead to step 3:
134 divided by 40 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 14 after subtracting 120 from 134.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 40

Step 4:
142 divided by 40 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 33.0
Subtract 120 from 142 to get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 40

Moving on to step 5:
40 goes into 228 5 times with a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 335.0
The remainder is 28 after subtracting 200 from 228.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 40

Going ahead to step 6:
The number 40 fits into 286 7 times, leaving a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 3357.0
Subtract 280 from 286 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
40 can be fit into 60 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 3357.1
If we take 40 away from 60, 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.

Advancing to step 8:
When dividing 200 by 40, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3357.15
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3357.15
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3357.15
Subtracting 0 from 0 leaves us 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 3357.15 and a remainder of 0.0.
