We're dividing 64770311 by 66 
We want to figure out the number of times 64770311 can be divided by 66.

Step 1:
66 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 66

Moving on to step 2:
When dividing 64 by 66, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (7) from the dividend, add it to 64, then carry on: 647 / 66

Going ahead to step 3:
The number 66 fits into 647 9 times, leaving a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 594 away from 647, we end up with 53.
Include the next digit (7) from the dividend after 53, then repeat: 537 / 66

On to step 4:
537 divided by 66 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we take 528 away from 537, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 66

Advancing to step 5:
66 can be fit into 90 1 times, resulting in a remainder of 24.
The next digit of our result is 1. 
Result so far: 981.0
Subtract 66 from 90 to get 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 66

Going ahead to step 6:
If we divide 243 by 66, we get 3 and a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 9813.0
Subtracting 198 from 243 leaves us with 45.
Take the next digit (1) from the dividend and append it to 45, then repeat: 451 / 66

Step 7:
66 goes into 451 6 times with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 98136.0
If we subtract 396 from 451, we get 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 66

Going ahead to step 8:
66 can be fit into 551 8 times, resulting in a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 981368.0
Subtract 528 from 551 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
The number 66 fits into 230 3 times, leaving a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 981368.3
Deduct 198 from 230 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
If we divide 320 by 66, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 981368.34
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 11:
66 can be fit into 560 8 times, resulting in a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 981368.348
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
66 can be fit into 320 4 times, resulting in a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 981368.3484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 13:
When dividing 560 by 66, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 981368.34848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
66 goes into 320 4 times with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 981368.348484
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 15:
66 can be fit into 560 8 times, resulting in a remainder of 32.
The next digit of our result is 8. 
Result so far: 981368.3484848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 16:
When dividing 320 by 66, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 981368.34848484
Subtract 264 from 320 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 981368.34848484, with a leftover of 5.6e-08.
