Let's divide 31504427 by 80
We want to figure out the number of times 31504427 can be divided by 80.

Going ahead to step 1:
80 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 80

On to step 2:
The number 80 fits into 31 0 times, leaving a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 31, we end up with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 80

Let's proceed to step 3:
If we divide 315 by 80, we get 3 and a remainder of 75.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 240 from 315 to get 75.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 80

Advancing to step 4:
80 can be fit into 750 9 times, resulting in a remainder of 30.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 720 away from 750, we end up with 30.
Take the next digit (4) from the dividend and append it to 30, then repeat: 304 / 80

Advancing to step 5:
304 divided by 80 is 3 with a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 393.0
Subtracting 240 from 304 leaves us with 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 80

Moving on to step 6:
When dividing 644 by 80, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 3938.0
Subtracting 640 from 644 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 80

Going ahead to step 7:
The number 80 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 39380.0
Subtract 0 from 42 to get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 80

Moving on to step 8:
The number 80 fits into 427 5 times, leaving a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 393805.0
The remainder is 27 after subtracting 400 from 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
270 divided by 80 is 3 with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 393805.3
Subtracting 240 from 270 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.

Advancing to step 10:
80 goes into 300 3 times with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 393805.33
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 393805.33 with a remaining 0.06.
