905003 ÷ 80 
Let's see how many times 80 fits into 905003.

Let's proceed to step 1:
80 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 80

Moving on to step 2:
90 divided by 80 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 10 after subtracting 80 from 90.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 80

Moving on to step 3:
The number 80 fits into 105 1 times, leaving a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 80 from 105 and we're left with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 80

Advancing to step 4:
The number 80 fits into 250 3 times, leaving a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 113.0
If we take 240 away from 250, we end up with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 80

Going ahead to step 5:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1131.0
If we subtract 80 from 100, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 80

Let's proceed to step 6:
When dividing 203 by 80, we get 2 with a remainder of 43.
The next digit of our result is 2. 
Result so far: 11312.0
Subtract 160 from 203 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
80 goes into 430 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 11312.5
If we take 400 away from 430, we end up 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.

Let's proceed to step 8:
80 goes into 300 3 times with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 11312.53
Subtracting 240 from 300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 11312.537
Subtract 560 from 600 to 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.

Let's proceed to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11312.5375
If we subtract 400 from 400, we 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.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11312.5375
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.

Going ahead to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 11312.5375
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 11312.5375 with a remaining 0.0.
