We look at the division of 361003 by 80 
We want to figure out the number of times 361003 can be divided by 80.

Let's proceed to step 1:
80 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 80

Going ahead to step 2:
The number 80 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 80

Step 3:
80 goes into 361 4 times with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 320 from 361 leaves us with 41.
Append the next digit (0) from the dividend to 41 and continue with: 410 / 80

Step 4:
If we divide 410 by 80, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 45.0
If we subtract 400 from 410, we get 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 80

Let's proceed to step 5:
80 goes into 100 1 times with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 451.0
Deduct 80 from 100 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 80

Going ahead to step 6:
80 goes into 203 2 times with a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 4512.0
The remainder is 43 after subtracting 160 from 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
If we divide 430 by 80, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 4512.5
Subtracting 400 from 430 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.

Moving on to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 4512.53
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 4512.537
The remainder is 40 after subtracting 560 from 600.
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 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4512.5375
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 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4512.5375
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.

On to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4512.5375
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.

After the division, we end up with 4512.5375 and a remainder of 0.0.
