We look at the division of 658740 by 91 
We're looking to find how many times 91 goes into 658740.

Let's proceed to 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
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 91

Going ahead to step 2:
91 can be fit into 65 0 times, resulting in a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 91

Step 3:
91 goes into 658 7 times with a remainder of 21.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 637 from 658 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 91

Advancing to step 4:
If we divide 217 by 91, we get 2 and a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Subtracting 182 from 217 leaves us with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 91

Moving on to step 5:
354 divided by 91 is 3 with a remainder of 81.
The next digit of our result is 3. 
Result so far: 723.0
If we take 273 away from 354, we end up with 81.
Include the next digit (0) from the dividend after 81, then repeat: 810 / 91

Moving on to step 6:
91 goes into 810 8 times with a remainder of 82.
The next digit of our result is 8. 
Result so far: 7238.0
If we subtract 728 from 810, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 7:
The number 91 fits into 820 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 7238.9
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
The number 91 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7238.9
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
The number 91 fits into 100 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 7238.901
If we subtract 91 from 100, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 10:
90 divided by 91 is 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 7238.901
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
91 goes into 900 9 times with a remainder of 81.
Record the quotient 9 as the next digit in the result. 
Result so far: 7238.90109
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 12:
When dividing 810 by 91, we get 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 7238.901098
Deduct 728 from 810 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 13:
The number 91 fits into 820 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 7238.9010989
Subtract 819 from 820 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
91 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 7238.9010989
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 7238.9010989 with a balance of 1e-08.
