We look at the division of 66764785 by 538 
We want to figure out the number of times 66764785 can be divided by 538.

Going ahead to step 1:
6 divided by 538 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 538

Advancing to step 2:
66 divided by 538 is 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 538

Moving on to step 3:
If we divide 667 by 538, we get 1 and a remainder of 129.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 538 from 667, we get 129.
Include the next digit (6) from the dividend after 129, then repeat: 1296 / 538

Let's proceed to step 4:
If we divide 1296 by 538, we get 2 and a remainder of 220.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 1076 from 1296 to get 220.
Fetch the next digit (4) from the dividend, attach it to 220 and continue: 2204 / 538

Advancing to step 5:
538 can be fit into 2204 4 times, resulting in a remainder of 52.
Put 4 as the next digit of the answer. 
Result so far: 124.0
The remainder is 52 after subtracting 2152 from 2204.
Append the next digit (7) from the dividend to 52 and continue with: 527 / 538

Advancing to step 6:
527 divided by 538 is 0 with a remainder of 527.
The number 0 becomes the next digit in our result. 
Result so far: 1240.0
If we take 0 away from 527, we end up with 527.
Fetch the next digit (8) from the dividend, attach it to 527 and continue: 5278 / 538

Going ahead to step 7:
The number 538 fits into 5278 9 times, leaving a remainder of 436.
Use 9 as the next digit of our solution. 
Result so far: 12409.0
Subtracting 4842 from 5278 leaves us with 436.
Append the next digit (5) from the dividend to 436 and continue with: 4365 / 538

Step 8:
The number 538 fits into 4365 8 times, leaving a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 124098.0
The remainder is 61 after subtracting 4304 from 4365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
610 divided by 538 is 1 with a remainder of 72.
Put 1 as the next digit of the answer. 
Result so far: 124098.1
Subtracting 538 from 610 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 10:
538 goes into 720 1 times with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 124098.11
The remainder is 182 after subtracting 538 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

After the division, we end up with 124098.11 and a remainder of 0.182.
