Let's divide 816040 by 91
We want to figure out the number of times 816040 can be divided by 91.

Step 1:
When dividing 8 by 91, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 91

Advancing to step 2:
The number 91 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 91

Going ahead to step 3:
The number 91 fits into 816 8 times, leaving a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 728 from 816, we get 88.
Include the next digit (0) from the dividend after 88, then repeat: 880 / 91

Moving on to step 4:
91 goes into 880 9 times with a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 61 after subtracting 819 from 880.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 91

Step 5:
The number 91 fits into 614 6 times, leaving a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 896.0
If we take 546 away from 614, we end up with 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 91

On to step 6:
680 divided by 91 is 7 with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 8967.0
The remainder is 43 after subtracting 637 from 680.
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:
430 divided by 91 is 4 with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 8967.4
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 8:
91 can be fit into 660 7 times, resulting in a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 8967.47
Subtracting 637 from 660 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 9:
230 divided by 91 is 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 8967.472
If we subtract 182 from 230, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
91 can be fit into 480 5 times, resulting in a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 8967.4725
Subtracting 455 from 480 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 11:
When dividing 250 by 91, we get 2 with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 8967.47252
The remainder is 68 after subtracting 182 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 12:
If we divide 680 by 91, we get 7 and a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 8967.472527
If we take 637 away from 680, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 13:
430 divided by 91 is 4 with a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 8967.4725274
Subtracting 364 from 430 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
660 divided by 91 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 8967.47252747
If we take 637 away from 660, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 8967.47252747 and a remainder of 2.3e-08.
