We're dividing 437066 by 80 
We want to divide 437066 by 80.

Moving on to step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left 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 next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 80

On to step 3:
The number 80 fits into 437 5 times, leaving a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 37 after subtracting 400 from 437.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 80

Moving on to step 4:
370 divided by 80 is 4 with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtract 320 from 370 to get 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 80

On to step 5:
When dividing 506 by 80, we get 6 with a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 546.0
The remainder is 26 after subtracting 480 from 506.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 80

On to step 6:
80 can be fit into 266 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 5463.0
Subtract 240 from 266 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
80 can be fit into 260 3 times, resulting in a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 5463.3
Subtract 240 from 260 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 80, we get 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 5463.32
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
80 goes into 400 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5463.325
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.

Moving on to step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5463.325
If we take 0 away from 0, 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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5463.325
If we take 0 away from 0, 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.

Our division results in 5463.325 with a remaining 0.0.
