We divide 809445 by 91
Let's see how many times 91 fits into 809445.

On to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 91

Let's proceed to step 2:
80 divided by 91 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (9) from the dividend after 80, then repeat: 809 / 91

Step 3:
91 can be fit into 809 8 times, resulting in a remainder of 81.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 728 from 809 and we're left with 81.
Take the next digit (4) from the dividend and append it to 81, then repeat: 814 / 91

On to step 4:
91 goes into 814 8 times with a remainder of 86.
The next digit of our result is 8. 
Result so far: 88.0
Subtracting 728 from 814 leaves us with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 91

On to step 5:
When dividing 864 by 91, we get 9 with a remainder of 45.
The number 9 becomes the next digit in our result. 
Result so far: 889.0
If we take 819 away from 864, we end up with 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 91

Let's proceed to step 6:
If we divide 455 by 91, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8895.0
If we take 455 away from 455, 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.

Advancing to step 7:
If we divide 0 by 91, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8895.0
Deduct 0 from 0 and we're left 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.

Going ahead to step 8:
When dividing 0 by 91, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8895.0
If we subtract 0 from 0, 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.

Our division results in 8895.0 with a remaining 0.0.
