We're dividing 34198878 by 757 
The aim is to understand the frequency of 757 in 34198878.

Let's proceed to step 1:
3 divided by 757 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 757

On to step 2:
The number 757 fits into 34 0 times, leaving a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 34, we end up with 34.
Include the next digit (1) from the dividend after 34, then repeat: 341 / 757

On to step 3:
757 goes into 341 0 times with a remainder of 341.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 341 and we're left with 341.
Include the next digit (9) from the dividend after 341, then repeat: 3419 / 757

Advancing to step 4:
757 goes into 3419 4 times with a remainder of 391.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 3028 away from 3419, we end up with 391.
Bring next digit (8) of the dividend behind the 391 and repeat the process: 3918 / 757

On to step 5:
The number 757 fits into 3918 5 times, leaving a remainder of 133.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 3785 from 3918 leaves us with 133.
Bring next digit (8) of the dividend behind the 133 and repeat the process: 1338 / 757

Step 6:
757 can be fit into 1338 1 times, resulting in a remainder of 581.
The number 1 becomes the next digit in our result. 
Result so far: 451.0
Deduct 757 from 1338 and we're left with 581.
Include the next digit (7) from the dividend after 581, then repeat: 5817 / 757

Step 7:
757 can be fit into 5817 7 times, resulting in a remainder of 518.
Record the quotient 7 as the next digit in the result. 
Result so far: 4517.0
If we subtract 5299 from 5817, we get 518.
Take the next digit (8) from the dividend and append it to 518, then repeat: 5188 / 757

Step 8:
When dividing 5188 by 757, we get 6 with a remainder of 646.
Record the quotient 6 as the next digit in the result. 
Result so far: 45176.0
Subtract 4542 from 5188 to get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Step 9:
If we divide 6460 by 757, we get 8 and a remainder of 404.
The number 8 becomes the next digit in our result. 
Result so far: 45176.8
Subtracting 6056 from 6460 leaves us with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 10:
If we divide 4040 by 757, we get 5 and a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 45176.85
If we subtract 3785 from 4040, we get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Let's proceed to step 11:
If we divide 2550 by 757, we get 3 and a remainder of 279.
Write down 3 as next digit of the result. 
Result so far: 45176.853
Subtract 2271 from 2550 to get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Advancing to step 12:
When dividing 2790 by 757, we get 3 with a remainder of 519.
Use 3 as the next digit of our solution. 
Result so far: 45176.8533
Subtracting 2271 from 2790 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

The final outcome is 45176.8533, with a leftover of 0.00519.
