We look at the division of 39415454 by 755 
The aim is to understand the frequency of 755 in 39415454.

Let's proceed to step 1:
When dividing 3 by 755, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 755

Step 2:
755 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (4) from the dividend after 39, then repeat: 394 / 755

On to step 3:
If we divide 394 by 755, we get 0 and a remainder of 394.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 394 to get 394.
Grab the next digit (1) from the dividend, add it to 394, then carry on: 3941 / 755

Let's proceed to step 4:
When dividing 3941 by 755, we get 5 with a remainder of 166.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3775 from 3941 leaves us with 166.
Include the next digit (5) from the dividend after 166, then repeat: 1665 / 755

On to step 5:
755 goes into 1665 2 times with a remainder of 155.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we take 1510 away from 1665, we end up with 155.
Fetch the next digit (4) from the dividend, attach it to 155 and continue: 1554 / 755

Let's proceed to step 6:
1554 divided by 755 is 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 522.0
Subtract 1510 from 1554 to get 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 755

Advancing to step 7:
755 goes into 445 0 times with a remainder of 445.
The next digit of our result is 0. 
Result so far: 5220.0
If we take 0 away from 445, we end up with 445.
Take the next digit (4) from the dividend and append it to 445, then repeat: 4454 / 755

Moving on to step 8:
4454 divided by 755 is 5 with a remainder of 679.
The number 5 becomes the next digit in our result. 
Result so far: 52205.0
Subtract 3775 from 4454 to get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Let's proceed to step 9:
755 can be fit into 6790 8 times, resulting in a remainder of 750.
Put 8 as the next digit of the answer. 
Result so far: 52205.8
Deduct 6040 from 6790 and we're left with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 10:
If we divide 7500 by 755, we get 9 and a remainder of 705.
Use 9 as the next digit of our solution. 
Result so far: 52205.89
If we subtract 6795 from 7500, we get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Let's proceed to step 11:
755 can be fit into 7050 9 times, resulting in a remainder of 255.
The number 9 becomes the next digit in our result. 
Result so far: 52205.899
Deduct 6795 from 7050 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

The final outcome is 52205.899, with a leftover of 0.0255.
