We divide 66764511 by 42
We want to figure out the number of times 66764511 can be divided by 42.

Going ahead to step 1:
If we divide 6 by 42, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 42

On to step 2:
66 divided by 42 is 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
If we take 42 away from 66, we end up with 24.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 42

Advancing to step 3:
If we divide 247 by 42, we get 5 and a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 37 after subtracting 210 from 247.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 42

Step 4:
376 divided by 42 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtract 336 from 376 to get 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 42

Advancing to step 5:
If we divide 404 by 42, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 1589.0
Subtracting 378 from 404 leaves us with 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 42

Advancing to step 6:
If we divide 265 by 42, we get 6 and a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 15896.0
The remainder is 13 after subtracting 252 from 265.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 42

Advancing to step 7:
42 goes into 131 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 158963.0
If we take 126 away from 131, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 42

Let's proceed to step 8:
The number 42 fits into 51 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1589631.0
Subtracting 42 from 51 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
If we divide 90 by 42, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1589631.2
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1589631.21
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 42, we get 4 and a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 1589631.214
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
42 can be fit into 120 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 1589631.2142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 1589631.21428
If we take 336 away from 360, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
42 goes into 240 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 1589631.214285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 15:
When dividing 300 by 42, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1589631.2142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 16:
60 divided by 42 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 1589631.21428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 1589631.21428571 with a remaining 1.8e-08.
