Let's divide 909973 by 91
We want to figure out the number of times 909973 can be divided by 91.

Step 1:
When dividing 9 by 91, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 91

Step 2:
When dividing 90 by 91, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Bring next digit (9) of the dividend behind the 90 and repeat the process: 909 / 91

Let's proceed to step 3:
91 goes into 909 9 times with a remainder of 90.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 819 from 909 leaves us with 90.
Include the next digit (9) from the dividend after 90, then repeat: 909 / 91

Step 4:
909 divided by 91 is 9 with a remainder of 90.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we subtract 819 from 909, we get 90.
Take the next digit (7) from the dividend and append it to 90, then repeat: 907 / 91

Let's proceed to step 5:
The number 91 fits into 907 9 times, leaving a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 999.0
Subtract 819 from 907 to get 88.
Take the next digit (3) from the dividend and append it to 88, then repeat: 883 / 91

Step 6:
883 divided by 91 is 9 with a remainder of 64.
The next digit of our result is 9. 
Result so far: 9999.0
Subtract 819 from 883 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
If we divide 640 by 91, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 9999.7
Deduct 637 from 640 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
91 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9999.7
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
The number 91 fits into 300 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 9999.703
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
91 goes into 270 2 times with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 9999.7032
Deduct 182 from 270 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
91 can be fit into 880 9 times, resulting in a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 9999.70329
Subtract 819 from 880 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
The number 91 fits into 610 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 9999.703296
The remainder is 64 after subtracting 546 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
The number 91 fits into 640 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 9999.7032967
If we take 637 away from 640, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 14:
30 divided by 91 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9999.7032967
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 9999.7032967 with a remainder of 3e-08.
