Let's divide 800661 by 91
We're looking to find how many times 91 goes into 800661.

Moving on to step 1:
The number 91 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 91

Let's proceed to step 2:
80 divided by 91 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (0) from the dividend after 80, then repeat: 800 / 91

Moving on to step 3:
800 divided by 91 is 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 728 from 800, we get 72.
Fetch the next digit (6) from the dividend, attach it to 72 and continue: 726 / 91

Let's proceed to step 4:
91 goes into 726 7 times with a remainder of 89.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we take 637 away from 726, we end up with 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 91

Moving on to step 5:
When dividing 896 by 91, we get 9 with a remainder of 77.
Record the quotient 9 as the next digit in the result. 
Result so far: 879.0
If we subtract 819 from 896, we get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 91

Advancing to step 6:
When dividing 771 by 91, we get 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 8798.0
The remainder is 43 after subtracting 728 from 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
If we divide 430 by 91, we get 4 and a remainder of 66.
The number 4 becomes the next digit in our result. 
Result so far: 8798.4
The remainder is 66 after subtracting 364 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
91 can be fit into 660 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 8798.47
Deduct 637 from 660 and we're left 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.

Let's proceed to step 9:
230 divided by 91 is 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 8798.472
Subtracting 182 from 230 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
If we divide 480 by 91, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 8798.4725
Deduct 455 from 480 and we're left 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.

Step 11:
If we divide 250 by 91, we get 2 and a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 8798.47252
If we take 182 away from 250, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
91 goes into 680 7 times with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 8798.472527
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.

Advancing to step 13:
430 divided by 91 is 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 8798.4725274
If we take 364 away from 430, we end up 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.

On to 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: 8798.47252747
Deduct 637 from 660 and we're left 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.

The final outcome is 8798.47252747, with a leftover of 2.3e-08.
