45690977 ÷ 728 
We want to figure out the number of times 45690977 can be divided by 728.

On to step 1:
If we divide 4 by 728, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 728

Going ahead to step 2:
If we divide 45 by 728, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (6) from the dividend to 45 and continue with: 456 / 728

Let's proceed to step 3:
The number 728 fits into 456 0 times, leaving a remainder of 456.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 456 to get 456.
Append the next digit (9) from the dividend to 456 and continue with: 4569 / 728

Going ahead to step 4:
728 goes into 4569 6 times with a remainder of 201.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 4368 from 4569 and we're left with 201.
Fetch the next digit (0) from the dividend, attach it to 201 and continue: 2010 / 728

Advancing to step 5:
2010 divided by 728 is 2 with a remainder of 554.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we subtract 1456 from 2010, we get 554.
Grab the next digit (9) from the dividend, add it to 554, then carry on: 5549 / 728

Advancing to step 6:
The number 728 fits into 5549 7 times, leaving a remainder of 453.
Put 7 as the next digit of the answer. 
Result so far: 627.0
Subtract 5096 from 5549 to get 453.
Append the next digit (7) from the dividend to 453 and continue with: 4537 / 728

On to step 7:
The number 728 fits into 4537 6 times, leaving a remainder of 169.
The number 6 becomes the next digit in our result. 
Result so far: 6276.0
The remainder is 169 after subtracting 4368 from 4537.
Append the next digit (7) from the dividend to 169 and continue with: 1697 / 728

Let's proceed to step 8:
1697 divided by 728 is 2 with a remainder of 241.
The number 2 becomes the next digit in our result. 
Result so far: 62762.0
If we take 1456 away from 1697, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Going ahead to step 9:
If we divide 2410 by 728, we get 3 and a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 62762.3
If we take 2184 away from 2410, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 10:
The number 728 fits into 2260 3 times, leaving a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 62762.33
Subtracting 2184 from 2260 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 62762.33 with a remaining 0.076.
