We divide 437545 by 80
We want to figure out the number of times 437545 can be divided by 80.

Moving on to 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
Subtracting 0 from 4 leaves us with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 80

Moving on to step 2:
If we divide 43 by 80, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 80

On to step 3:
The number 80 fits into 437 5 times, leaving a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 400 from 437, we get 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 80

Moving on to step 4:
If we divide 375 by 80, we get 4 and a remainder of 55.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 320 from 375 leaves us with 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 80

Step 5:
80 can be fit into 554 6 times, resulting in a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 546.0
Subtracting 480 from 554 leaves us with 74.
Append the next digit (5) from the dividend to 74 and continue with: 745 / 80

On to step 6:
If we divide 745 by 80, we get 9 and a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 5469.0
Deduct 720 from 745 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
80 can be fit into 250 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 5469.3
Deduct 240 from 250 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
80 goes into 100 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 5469.31
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 5469.312
If we subtract 160 from 200, we get 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 can be fit into 400 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5469.3125
If we take 400 away from 400, we end up 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.

Step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5469.3125
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.
The number 0 becomes the next digit in our result. 
Result so far: 5469.3125
Deduct 0 from 0 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.

The quotient of the division is 5469.3125, and the remainder is 0.0.
