We look at the division of 402066 by 54 
We want to figure out the number of times 402066 can be divided by 54.

Going ahead to step 1:
4 divided by 54 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 54

Advancing to step 2:
The number 54 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 54

Let's proceed to step 3:
When dividing 402 by 54, we get 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 378 from 402 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 54

Step 4:
The number 54 fits into 240 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we subtract 216 from 240, we get 24.
Take the next digit (6) from the dividend and append it to 24, then repeat: 246 / 54

Let's proceed to step 5:
54 can be fit into 246 4 times, resulting in a remainder of 30.
Use 4 as the next digit of our solution. 
Result so far: 744.0
If we subtract 216 from 246, we get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 54

Going ahead to step 6:
306 divided by 54 is 5 with a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 7445.0
If we subtract 270 from 306, 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.

On to step 7:
54 can be fit into 360 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 7445.6
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
54 can be fit into 360 6 times, resulting in a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 7445.66
Deduct 324 from 360 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 7445.66 and a remainder of 0.036.
