Let's divide 34453119 by 780
The aim is to understand the frequency of 780 in 34453119.

Advancing to step 1:
3 divided by 780 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 780

Step 2:
780 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 780

On to step 3:
The number 780 fits into 344 0 times, leaving a remainder of 344.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 344 leaves us with 344.
Take the next digit (5) from the dividend and append it to 344, then repeat: 3445 / 780

Moving on to step 4:
The number 780 fits into 3445 4 times, leaving a remainder of 325.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3120 from 3445, we get 325.
Fetch the next digit (3) from the dividend, attach it to 325 and continue: 3253 / 780

Moving on to step 5:
780 goes into 3253 4 times with a remainder of 133.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 3120 from 3253, we get 133.
Append the next digit (1) from the dividend to 133 and continue with: 1331 / 780

Moving on to step 6:
1331 divided by 780 is 1 with a remainder of 551.
Use 1 as the next digit of our solution. 
Result so far: 441.0
Subtract 780 from 1331 to get 551.
Grab the next digit (1) from the dividend, add it to 551, then carry on: 5511 / 780

Advancing to step 7:
The number 780 fits into 5511 7 times, leaving a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 4417.0
Subtracting 5460 from 5511 leaves us with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 780

Moving on to step 8:
780 can be fit into 519 0 times, resulting in a remainder of 519.
Put 0 as the next digit of the answer. 
Result so far: 44170.0
Subtract 0 from 519 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Step 9:
5190 divided by 780 is 6 with a remainder of 510.
Use 6 as the next digit of our solution. 
Result so far: 44170.6
Subtracting 4680 from 5190 leaves us with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 10:
When dividing 5100 by 780, we get 6 with a remainder of 420.
Write down 6 as next digit of the result. 
Result so far: 44170.66
Deduct 4680 from 5100 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Our division results in 44170.66 with a remaining 0.42.
