We look at the division of 81397409 by 741 
The aim is to understand the frequency of 741 in 81397409.

Going ahead to step 1:
8 divided by 741 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 741

Let's proceed to step 2:
81 divided by 741 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Bring next digit (3) of the dividend behind the 81 and repeat the process: 813 / 741

Advancing to step 3:
741 goes into 813 1 times with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 741 from 813 leaves us with 72.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 741

Moving on to step 4:
When dividing 729 by 741, we get 0 with a remainder of 729.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 729 after subtracting 0 from 729.
Bring next digit (7) of the dividend behind the 729 and repeat the process: 7297 / 741

Advancing to step 5:
When dividing 7297 by 741, we get 9 with a remainder of 628.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we take 6669 away from 7297, we end up with 628.
Grab the next digit (4) from the dividend, add it to 628, then carry on: 6284 / 741

Going ahead to step 6:
741 can be fit into 6284 8 times, resulting in a remainder of 356.
Write down 8 as next digit of the result. 
Result so far: 1098.0
Deduct 5928 from 6284 and we're left with 356.
Take the next digit (0) from the dividend and append it to 356, then repeat: 3560 / 741

Advancing to step 7:
3560 divided by 741 is 4 with a remainder of 596.
Record the quotient 4 as the next digit in the result. 
Result so far: 10984.0
Subtract 2964 from 3560 to get 596.
Take the next digit (9) from the dividend and append it to 596, then repeat: 5969 / 741

Let's proceed to step 8:
741 can be fit into 5969 8 times, resulting in a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 109848.0
Deduct 5928 from 5969 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 9:
410 divided by 741 is 0 with a remainder of 410.
The next digit of our result is 0. 
Result so far: 109848.0
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 10:
741 can be fit into 4100 5 times, resulting in a remainder of 395.
Put 5 as the next digit of the answer. 
Result so far: 109848.05
If we subtract 3705 from 4100, we get 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 11:
3950 divided by 741 is 5 with a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 109848.055
If we subtract 3705 from 3950, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

In conclusion, the division gives 109848.055 with a balance of 0.0245.
