664322 ÷ 91 
We want to divide 664322 by 91.

Step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 91

Step 2:
91 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 91

Step 3:
91 can be fit into 664 7 times, resulting in a remainder of 27.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 637 from 664 leaves us with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 91

Advancing to step 4:
If we divide 273 by 91, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
Subtracting 273 from 273 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 91

On to step 5:
91 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 730.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 91

Advancing to step 6:
The number 91 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 7300.0
Deduct 0 from 22 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
220 divided by 91 is 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 7300.2
If we subtract 182 from 220, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
When dividing 380 by 91, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 7300.24
Subtract 364 from 380 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
91 can be fit into 160 1 times, resulting in a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 7300.241
Subtract 91 from 160 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 10:
The number 91 fits into 690 7 times, leaving a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 7300.2417
Subtract 637 from 690 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
The number 91 fits into 530 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 7300.24175
Subtracting 455 from 530 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
91 goes into 750 8 times with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 7300.241758
The remainder is 22 after subtracting 728 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
91 goes into 220 2 times with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 7300.2417582
If we subtract 182 from 220, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
When dividing 380 by 91, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 7300.24175824
If we take 364 away from 380, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 7300.24175824 with a balance of 1.6e-08.
