81941953 divided by 52 
The aim is to understand the frequency of 52 in 81941953.

Step 1:
The number 52 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 52

Let's proceed to step 2:
When dividing 81 by 52, we get 1 with a remainder of 29.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 52 from 81 to get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 52

Advancing to step 3:
If we divide 299 by 52, we get 5 and a remainder of 39.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 260 from 299 to get 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 52

Moving on to step 4:
When dividing 394 by 52, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 157.0
Subtract 364 from 394 to get 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 52

Let's proceed to step 5:
52 can be fit into 301 5 times, resulting in a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 1575.0
Deduct 260 from 301 and we're left with 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 52

On to step 6:
52 goes into 419 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 15758.0
If we subtract 416 from 419, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 52

Step 7:
52 goes into 35 0 times with a remainder of 35.
The next digit of our result is 0. 
Result so far: 157580.0
If we subtract 0 from 35, we get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 52

On to step 8:
When dividing 353 by 52, we get 6 with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 1575806.0
Subtract 312 from 353 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 9:
52 goes into 410 7 times with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 1575806.7
If we subtract 364 from 410, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
When dividing 460 by 52, we get 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 1575806.78
If we subtract 416 from 460, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 11:
When dividing 440 by 52, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 1575806.788
Deduct 416 from 440 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 1575806.788 with a balance of 0.0024.
