437970 divided by 80 
Let's see how many times 80 fits into 437970.

Advancing to step 1:
80 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 80

On to step 2:
80 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 80

Advancing to step 3:
80 goes into 437 5 times with a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 400 from 437 leaves us with 37.
Append the next digit (9) from the dividend to 37 and continue with: 379 / 80

Advancing to step 4:
379 divided by 80 is 4 with a remainder of 59.
The next digit of our result is 4. 
Result so far: 54.0
Subtracting 320 from 379 leaves us with 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 80

Going ahead to step 5:
80 goes into 597 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 547.0
The remainder is 37 after subtracting 560 from 597.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 80

Advancing to step 6:
80 goes into 370 4 times with a remainder of 50.
The next digit of our result is 4. 
Result so far: 5474.0
If we take 320 away from 370, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
80 goes into 500 6 times with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 5474.6
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 5474.62
If we take 160 away from 200, we end up 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.

Moving on to step 9:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5474.625
Subtract 400 from 400 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.

Advancing to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5474.625
Subtracting 0 from 0 leaves us 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.

Moving on to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5474.625
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 5474.625 and a remainder of 0.0.
