We're dividing 66478601 by 539 
We want to divide 66478601 by 539.

Let's proceed to step 1:
If we divide 6 by 539, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 539

Moving on to step 2:
539 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 539

On to step 3:
The number 539 fits into 664 1 times, leaving a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 539 from 664 leaves us with 125.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 539

Moving on to step 4:
When dividing 1257 by 539, we get 2 with a remainder of 179.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 1078 from 1257 leaves us with 179.
Fetch the next digit (8) from the dividend, attach it to 179 and continue: 1798 / 539

Advancing to step 5:
When dividing 1798 by 539, we get 3 with a remainder of 181.
Write down 3 as next digit of the result. 
Result so far: 123.0
If we take 1617 away from 1798, we end up with 181.
Bring next digit (6) of the dividend behind the 181 and repeat the process: 1816 / 539

Moving on to step 6:
The number 539 fits into 1816 3 times, leaving a remainder of 199.
Use 3 as the next digit of our solution. 
Result so far: 1233.0
Deduct 1617 from 1816 and we're left with 199.
Take the next digit (0) from the dividend and append it to 199, then repeat: 1990 / 539

Let's proceed to step 7:
When dividing 1990 by 539, we get 3 with a remainder of 373.
Write down 3 as next digit of the result. 
Result so far: 12333.0
Subtract 1617 from 1990 to get 373.
Fetch the next digit (1) from the dividend, attach it to 373 and continue: 3731 / 539

Step 8:
539 can be fit into 3731 6 times, resulting in a remainder of 497.
Write down 6 as next digit of the result. 
Result so far: 123336.0
If we subtract 3234 from 3731, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Advancing to step 9:
4970 divided by 539 is 9 with a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 123336.9
The remainder is 119 after subtracting 4851 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 10:
When dividing 1190 by 539, we get 2 with a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 123336.92
Subtract 1078 from 1190 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 11:
If we divide 1120 by 539, we get 2 and a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 123336.922
If we subtract 1078 from 1120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 123336.922 with a remainder of 0.0042.
