We look at the division of 664717 by 91 
We want to figure out the number of times 664717 can be divided by 91.

Let's proceed to step 1:
6 divided by 91 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 91

Let's proceed to step 2:
If we divide 66 by 91, we get 0 and 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.
Grab the next digit (4) from the dividend, add it to 66, then carry on: 664 / 91

Going ahead to 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
Subtract 637 from 664 to get 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 91

Going ahead to step 4:
When dividing 277 by 91, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
If we subtract 273 from 277, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 91

On to step 5:
The number 91 fits into 41 0 times, leaving a remainder of 41.
The next digit of our result is 0. 
Result so far: 730.0
If we take 0 away from 41, we end up with 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 91

Going ahead to step 6:
417 divided by 91 is 4 with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 7304.0
If we take 364 away from 417, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 7:
530 divided by 91 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7304.5
If we subtract 455 from 530, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
When dividing 750 by 91, we get 8 with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 7304.58
Subtracting 728 from 750 leaves us 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.

On to step 9:
When dividing 220 by 91, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 7304.582
The remainder is 38 after subtracting 182 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 10:
When dividing 380 by 91, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 7304.5824
The remainder is 16 after subtracting 364 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
When dividing 160 by 91, we get 1 with a remainder of 69.
The number 1 becomes the next digit in our result. 
Result so far: 7304.58241
If we take 91 away from 160, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
690 divided by 91 is 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 7304.582417
The remainder is 53 after subtracting 637 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
91 can be fit into 530 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 7304.5824175
Subtract 455 from 530 to get 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 14:
If we divide 750 by 91, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 7304.58241758
Deduct 728 from 750 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.

The final result is 7304.58241758 with a remainder of 2.2e-08.
