66787689 ÷ 764 
We want to figure out the number of times 66787689 can be divided by 764.

Let's proceed to step 1:
When dividing 6 by 764, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 764

Let's proceed to step 2:
If we divide 66 by 764, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (7) from the dividend, add it to 66, then carry on: 667 / 764

Going ahead to step 3:
The number 764 fits into 667 0 times, leaving a remainder of 667.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 667, we end up with 667.
Bring next digit (8) of the dividend behind the 667 and repeat the process: 6678 / 764

Going ahead to step 4:
764 can be fit into 6678 8 times, resulting in a remainder of 566.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 6112 away from 6678, we end up with 566.
Include the next digit (7) from the dividend after 566, then repeat: 5667 / 764

Advancing to step 5:
If we divide 5667 by 764, we get 7 and a remainder of 319.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtracting 5348 from 5667 leaves us with 319.
Take the next digit (6) from the dividend and append it to 319, then repeat: 3196 / 764

Let's proceed to step 6:
If we divide 3196 by 764, we get 4 and a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 874.0
Subtracting 3056 from 3196 leaves us with 140.
Append the next digit (8) from the dividend to 140 and continue with: 1408 / 764

On to step 7:
764 goes into 1408 1 times with a remainder of 644.
Use 1 as the next digit of our solution. 
Result so far: 8741.0
If we take 764 away from 1408, we end up with 644.
Take the next digit (9) from the dividend and append it to 644, then repeat: 6449 / 764

On to step 8:
The number 764 fits into 6449 8 times, leaving a remainder of 337.
The number 8 becomes the next digit in our result. 
Result so far: 87418.0
If we subtract 6112 from 6449, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

On to step 9:
764 goes into 3370 4 times with a remainder of 314.
Record the quotient 4 as the next digit in the result. 
Result so far: 87418.4
Subtracting 3056 from 3370 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Advancing to step 10:
764 can be fit into 3140 4 times, resulting in a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 87418.44
If we subtract 3056 from 3140, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

After the division, we end up with 87418.44 and a remainder of 0.084.
