45949982 divided by 80 
We want to figure out the number of times 45949982 can be divided by 80.

Step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 80

On to step 2:
If we divide 45 by 80, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Fetch the next digit (9) from the dividend, attach it to 45 and continue: 459 / 80

Moving on to step 3:
When dividing 459 by 80, we get 5 with a remainder of 59.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 400 from 459 to get 59.
Bring next digit (4) of the dividend behind the 59 and repeat the process: 594 / 80

Going ahead to step 4:
The number 80 fits into 594 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 34 after subtracting 560 from 594.
Fetch the next digit (9) from the dividend, attach it to 34 and continue: 349 / 80

On to step 5:
If we divide 349 by 80, we get 4 and a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 574.0
Subtracting 320 from 349 leaves us with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 80

Let's proceed to step 6:
When dividing 299 by 80, we get 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 5743.0
Subtract 240 from 299 to get 59.
Grab the next digit (8) from the dividend, add it to 59, then carry on: 598 / 80

On to step 7:
The number 80 fits into 598 7 times, leaving a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 57437.0
The remainder is 38 after subtracting 560 from 598.
Bring next digit (2) of the dividend behind the 38 and repeat the process: 382 / 80

Going ahead to step 8:
The number 80 fits into 382 4 times, leaving a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 574374.0
Deduct 320 from 382 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 9:
When dividing 620 by 80, we get 7 with a remainder of 60.
Record the quotient 7 as the next digit in the result. 
Result so far: 574374.7
If we take 560 away from 620, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 10:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 574374.77
Subtracting 560 from 600 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 574374.77 with a remaining 0.04.
