We divide 1083602 by 803
We're looking to find how many times 803 goes into 1083602.

Step 1:
The number 803 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 803

Moving on to step 2:
The number 803 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 803

Moving on to step 3:
803 goes into 108 0 times with a remainder of 108.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 108, we get 108.
Include the next digit (3) from the dividend after 108, then repeat: 1083 / 803

Going ahead to step 4:
When dividing 1083 by 803, we get 1 with a remainder of 280.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 803 from 1083, we get 280.
Append the next digit (6) from the dividend to 280 and continue with: 2806 / 803

Going ahead to step 5:
When dividing 2806 by 803, we get 3 with a remainder of 397.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 2409 away from 2806, we end up with 397.
Bring next digit (0) of the dividend behind the 397 and repeat the process: 3970 / 803

Moving on to step 6:
When dividing 3970 by 803, we get 4 with a remainder of 758.
Use 4 as the next digit of our solution. 
Result so far: 134.0
The remainder is 758 after subtracting 3212 from 3970.
Grab the next digit (2) from the dividend, add it to 758, then carry on: 7582 / 803

Moving on to step 7:
The number 803 fits into 7582 9 times, leaving a remainder of 355.
The next digit of our result is 9. 
Result so far: 1349.0
Subtract 7227 from 7582 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 8:
When dividing 3550 by 803, we get 4 with a remainder of 338.
Put 4 as the next digit of the answer. 
Result so far: 1349.4
If we subtract 3212 from 3550, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 9:
3380 divided by 803 is 4 with a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 1349.44
Subtract 3212 from 3380 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

After the division, we end up with 1349.44 and a remainder of 0.168.
