We're dividing 385858 by 66 
We want to figure out the number of times 385858 can be divided by 66.

Going ahead to step 1:
3 divided by 66 is 0 with 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.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 66

Step 2:
66 can be fit into 38 0 times, resulting in a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 66

Let's proceed to step 3:
66 can be fit into 385 5 times, resulting in a remainder of 55.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 330 from 385, we get 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 66

Advancing to step 4:
558 divided by 66 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 58.0
Deduct 528 from 558 and we're left with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 66

Step 5:
The number 66 fits into 305 4 times, leaving a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 584.0
Deduct 264 from 305 and we're left with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 66

Step 6:
The number 66 fits into 418 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 5846.0
If we subtract 396 from 418, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
When dividing 220 by 66, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 5846.3
If we subtract 198 from 220, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
66 can be fit into 220 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 5846.33
If we take 198 away from 220, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 5846.33 with a remainder of 0.022.
