We look at the division of 66542999 by 481 
We want to divide 66542999 by 481.

On to step 1:
6 divided by 481 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 481

Advancing to step 2:
If we divide 66 by 481, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Fetch the next digit (5) from the dividend, attach it to 66 and continue: 665 / 481

Moving on to step 3:
481 can be fit into 665 1 times, resulting in a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 481 away from 665, we end up with 184.
Bring next digit (4) of the dividend behind the 184 and repeat the process: 1844 / 481

On to step 4:
481 goes into 1844 3 times with a remainder of 401.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1443 from 1844 to get 401.
Bring next digit (2) of the dividend behind the 401 and repeat the process: 4012 / 481

Step 5:
When dividing 4012 by 481, we get 8 with a remainder of 164.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtracting 3848 from 4012 leaves us with 164.
Fetch the next digit (9) from the dividend, attach it to 164 and continue: 1649 / 481

Moving on to step 6:
1649 divided by 481 is 3 with a remainder of 206.
Use 3 as the next digit of our solution. 
Result so far: 1383.0
Deduct 1443 from 1649 and we're left with 206.
Bring next digit (9) of the dividend behind the 206 and repeat the process: 2069 / 481

Moving on to step 7:
If we divide 2069 by 481, we get 4 and a remainder of 145.
The number 4 becomes the next digit in our result. 
Result so far: 13834.0
The remainder is 145 after subtracting 1924 from 2069.
Fetch the next digit (9) from the dividend, attach it to 145 and continue: 1459 / 481

Let's proceed to step 8:
The number 481 fits into 1459 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 138343.0
Subtract 1443 from 1459 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
If we divide 160 by 481, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 138343.0
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 10:
If we divide 1600 by 481, we get 3 and a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 138343.03
The remainder is 157 after subtracting 1443 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 11:
If we divide 1570 by 481, we get 3 and a remainder of 127.
The next digit of our result is 3. 
Result so far: 138343.033
The remainder is 127 after subtracting 1443 from 1570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The final result is 138343.033 with a remainder of 0.0127.
