We look at the division of 66854494 by 30 
We want to divide 66854494 by 30.

Advancing to step 1:
The number 30 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 30

Advancing to step 2:
The number 30 fits into 66 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 60 from 66 and we're left with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 30

Moving on to step 3:
30 goes into 68 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 60 from 68 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 30

Moving on to step 4:
The number 30 fits into 85 2 times, leaving a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
If we subtract 60 from 85, we get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 30

Step 5:
30 can be fit into 254 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 2228.0
If we take 240 away from 254, we end up with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 30

Advancing to step 6:
144 divided by 30 is 4 with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 22284.0
Subtracting 120 from 144 leaves us with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 30

Moving on to step 7:
If we divide 249 by 30, we get 8 and a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 222848.0
Subtract 240 from 249 to get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 30

Going ahead to step 8:
The number 30 fits into 94 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 2228483.0
The remainder is 4 after subtracting 90 from 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 30 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2228483.1
If we subtract 30 from 40, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 2228483.13
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
100 divided by 30 is 3 with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 2228483.133
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 2228483.133 with a remaining 0.001.
