45691815 divided by 768 
We want to figure out the number of times 45691815 can be divided by 768.

Step 1:
768 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 768

Moving on to step 2:
768 goes into 45 0 times with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 768

Step 3:
768 can be fit into 456 0 times, resulting in a remainder of 456.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 456 and we're left with 456.
Append the next digit (9) from the dividend to 456 and continue with: 4569 / 768

On to step 4:
If we divide 4569 by 768, we get 5 and a remainder of 729.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 3840 from 4569 and we're left with 729.
Append the next digit (1) from the dividend to 729 and continue with: 7291 / 768

Let's proceed to step 5:
When dividing 7291 by 768, we get 9 with a remainder of 379.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtracting 6912 from 7291 leaves us with 379.
Fetch the next digit (8) from the dividend, attach it to 379 and continue: 3798 / 768

Advancing to step 6:
The number 768 fits into 3798 4 times, leaving a remainder of 726.
Put 4 as the next digit of the answer. 
Result so far: 594.0
Deduct 3072 from 3798 and we're left with 726.
Include the next digit (1) from the dividend after 726, then repeat: 7261 / 768

Moving on to step 7:
When dividing 7261 by 768, we get 9 with a remainder of 349.
The number 9 becomes the next digit in our result. 
Result so far: 5949.0
Deduct 6912 from 7261 and we're left with 349.
Append the next digit (5) from the dividend to 349 and continue with: 3495 / 768

Advancing to step 8:
If we divide 3495 by 768, we get 4 and a remainder of 423.
The next digit of our result is 4. 
Result so far: 59494.0
The remainder is 423 after subtracting 3072 from 3495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Going ahead to step 9:
768 goes into 4230 5 times with a remainder of 390.
The number 5 becomes the next digit in our result. 
Result so far: 59494.5
The remainder is 390 after subtracting 3840 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 10:
768 goes into 3900 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 59494.55
Subtract 3840 from 3900 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 59494.55 with a remaining 0.06.
