We look at the division of 428045 by 80 
Our goal is to divide 428045 by 80.

Let's proceed to step 1:
The number 80 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 80

Going ahead to step 2:
80 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 80

Advancing to step 3:
The number 80 fits into 428 5 times, leaving a remainder of 28.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 400 away from 428, we end up with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 80

Advancing to step 4:
The number 80 fits into 280 3 times, leaving a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtracting 240 from 280 leaves us with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 80

Advancing to step 5:
80 can be fit into 404 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 535.0
If we subtract 400 from 404, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 80

Step 6:
When dividing 45 by 80, we get 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 5350.0
If we subtract 0 from 45, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
When dividing 450 by 80, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 5350.5
Subtract 400 from 450 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 5350.56
Deduct 480 from 500 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 5350.562
Deduct 160 from 200 and we're left 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.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5350.5625
Deduct 400 from 400 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5350.5625
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.

Moving on to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5350.5625
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.

The quotient of the division is 5350.5625, and the remainder is 0.0.
