80340955 divided by 803 
Let's see how many times 803 fits into 80340955.

Let's proceed to step 1:
If we divide 8 by 803, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 803

On to step 2:
The number 803 fits into 80 0 times, leaving a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 803

On to step 3:
The number 803 fits into 803 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 803 from 803.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 803

Step 4:
4 divided by 803 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 803

Moving on to step 5:
When dividing 40 by 803, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 803

Going ahead to step 6:
When dividing 409 by 803, we get 0 with a remainder of 409.
Write down 0 as next digit of the result. 
Result so far: 1000.0
If we subtract 0 from 409, we get 409.
Take the next digit (5) from the dividend and append it to 409, then repeat: 4095 / 803

Advancing to step 7:
4095 divided by 803 is 5 with a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 10005.0
If we take 4015 away from 4095, we end up with 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 803

Step 8:
805 divided by 803 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 100051.0
Subtract 803 from 805 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 803 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 100051.0
If we subtract 0 from 20, we 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 10:
The number 803 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 100051.0
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 100051.0 with a remaining 0.2.
