Let's divide 710073 by 91
The aim is to understand the frequency of 91 in 710073.

Advancing to step 1:
91 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 91

Let's proceed to step 2:
91 can be fit into 71 0 times, resulting in a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Include the next digit (0) from the dividend after 71, then repeat: 710 / 91

On to step 3:
The number 91 fits into 710 7 times, leaving a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 637 from 710, we get 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 91

Moving on to step 4:
730 divided by 91 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 728 from 730 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 91

Advancing to step 5:
The number 91 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
Deduct 0 from 27 and we're left with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 91

Let's proceed to step 6:
When dividing 273 by 91, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 7803.0
The remainder is 0 after subtracting 273 from 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
91 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7803.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
0 divided by 91 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7803.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 7803.0 and a remainder of 0.0.
