Let's divide 72958543 by 835
The aim is to understand the frequency of 835 in 72958543.

Moving on to step 1:
7 divided by 835 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 835

Going ahead to step 2:
835 can be fit into 72 0 times, resulting in a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 835

Let's proceed to step 3:
835 goes into 729 0 times with a remainder of 729.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 729 after subtracting 0 from 729.
Take the next digit (5) from the dividend and append it to 729, then repeat: 7295 / 835

Going ahead to step 4:
When dividing 7295 by 835, we get 8 with a remainder of 615.
The next digit of our result is 8. 
Result so far: 8.0
If we take 6680 away from 7295, we end up with 615.
Take the next digit (8) from the dividend and append it to 615, then repeat: 6158 / 835

On to step 5:
835 can be fit into 6158 7 times, resulting in a remainder of 313.
The next digit of our result is 7. 
Result so far: 87.0
If we take 5845 away from 6158, we end up with 313.
Include the next digit (5) from the dividend after 313, then repeat: 3135 / 835

Moving on to step 6:
835 goes into 3135 3 times with a remainder of 630.
Use 3 as the next digit of our solution. 
Result so far: 873.0
The remainder is 630 after subtracting 2505 from 3135.
Grab the next digit (4) from the dividend, add it to 630, then carry on: 6304 / 835

Going ahead to step 7:
If we divide 6304 by 835, we get 7 and a remainder of 459.
The next digit of our result is 7. 
Result so far: 8737.0
Subtracting 5845 from 6304 leaves us with 459.
Include the next digit (3) from the dividend after 459, then repeat: 4593 / 835

Advancing to step 8:
When dividing 4593 by 835, we get 5 with a remainder of 418.
Use 5 as the next digit of our solution. 
Result so far: 87375.0
The remainder is 418 after subtracting 4175 from 4593.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Advancing to step 9:
The number 835 fits into 4180 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 87375.5
Subtracting 4175 from 4180 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
835 goes into 50 0 times with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 87375.5
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
If we divide 500 by 835, we get 0 and a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 87375.5
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 87375.5 with a remaining 0.05.
