Let's divide 660544 by 91
Let's see how many times 91 fits into 660544.

Step 1:
The number 91 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 91

Advancing to step 2:
The number 91 fits into 66 0 times, leaving a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 91

Let's proceed to step 3:
91 can be fit into 660 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 637 away from 660, we end up with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 91

Moving on to step 4:
If we divide 235 by 91, we get 2 and a remainder of 53.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
If we subtract 182 from 235, we get 53.
Take the next digit (4) from the dividend and append it to 53, then repeat: 534 / 91

Moving on to step 5:
534 divided by 91 is 5 with a remainder of 79.
The next digit of our result is 5. 
Result so far: 725.0
If we subtract 455 from 534, we get 79.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 91

Going ahead to step 6:
794 divided by 91 is 8 with a remainder of 66.
The next digit of our result is 8. 
Result so far: 7258.0
Deduct 728 from 794 and we're left 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.

Advancing to step 7:
When dividing 660 by 91, we get 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 7258.7
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 8:
91 goes into 230 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 7258.72
Subtract 182 from 230 to 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.

Let's proceed to step 9:
The number 91 fits into 480 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 7258.725
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.

Let's proceed to step 10:
91 goes into 250 2 times with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 7258.7252
If we subtract 182 from 250, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
91 can be fit into 680 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 7258.72527
Subtract 637 from 680 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 12:
If we divide 430 by 91, we get 4 and a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 7258.725274
Subtract 364 from 430 to 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.

Advancing to step 13:
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: 7258.7252747
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.

Advancing to step 14:
The number 91 fits into 230 2 times, leaving a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 7258.72527472
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.

After the division, we end up with 7258.72527472 and a remainder of 4.8e-08.
