We look at the division of 803090 by 91 
We want to figure out the number of times 803090 can be divided by 91.

Advancing to step 1:
If we divide 8 by 91, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 91

On to step 2:
80 divided by 91 is 0 with 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.
Fetch the next digit (3) from the dividend, attach it to 80 and continue: 803 / 91

Going ahead to step 3:
If we divide 803 by 91, we get 8 and a remainder of 75.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 728 from 803 to get 75.
Append the next digit (0) from the dividend to 75 and continue with: 750 / 91

Step 4:
When dividing 750 by 91, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 88.0
The remainder is 22 after subtracting 728 from 750.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 91

Advancing to step 5:
The number 91 fits into 229 2 times, leaving a remainder of 47.
Use 2 as the next digit of our solution. 
Result so far: 882.0
The remainder is 47 after subtracting 182 from 229.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 91

Let's proceed to step 6:
The number 91 fits into 470 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8825.0
Subtracting 455 from 470 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
91 goes into 150 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 8825.1
If we take 91 away from 150, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 8:
The number 91 fits into 590 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 8825.16
The remainder is 44 after subtracting 546 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 91, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 8825.164
Subtract 364 from 440 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
The number 91 fits into 760 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8825.1648
The remainder is 32 after subtracting 728 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
91 goes into 320 3 times with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 8825.16483
If we take 273 away from 320, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 12:
91 goes into 470 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 8825.164835
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
When dividing 150 by 91, we get 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 8825.1648351
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 14:
91 goes into 590 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 8825.16483516
Subtracting 546 from 590 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 8825.16483516 with a remaining 4.4e-08.
