Let's divide 445403 by 80
We want to figure out the number of times 445403 can be divided by 80.

Step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 80

Going ahead to step 2:
80 goes into 44 0 times with a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 80

On to step 3:
80 can be fit into 445 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 400 from 445 leaves us with 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 80

Advancing to step 4:
If we divide 454 by 80, we get 5 and a remainder of 54.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we take 400 away from 454, we end up with 54.
Grab the next digit (0) from the dividend, add it to 54, then carry on: 540 / 80

Moving on to step 5:
80 can be fit into 540 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 556.0
If we subtract 480 from 540, we get 60.
Fetch the next digit (3) from the dividend, attach it to 60 and continue: 603 / 80

Let's proceed to step 6:
When dividing 603 by 80, we get 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 5567.0
Deduct 560 from 603 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 7:
430 divided by 80 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5567.5
Subtracting 400 from 430 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
The next digit of our result is 3. 
Result so far: 5567.53
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
80 goes into 600 7 times with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 5567.537
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.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5567.5375
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5567.5375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5567.5375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 5567.5375 and a remainder of 0.0.
