We look at the division of 43120412 by 779 
The aim is to understand the frequency of 779 in 43120412.

Moving on to step 1:
When dividing 4 by 779, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 779

Let's proceed to step 2:
779 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 779

Let's proceed to step 3:
If we divide 431 by 779, we get 0 and a remainder of 431.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 431 to get 431.
Include the next digit (2) from the dividend after 431, then repeat: 4312 / 779

Step 4:
The number 779 fits into 4312 5 times, leaving a remainder of 417.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 3895 from 4312 leaves us with 417.
Include the next digit (0) from the dividend after 417, then repeat: 4170 / 779

Going ahead to step 5:
The number 779 fits into 4170 5 times, leaving a remainder of 275.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 3895 from 4170 leaves us with 275.
Bring next digit (4) of the dividend behind the 275 and repeat the process: 2754 / 779

Step 6:
If we divide 2754 by 779, we get 3 and a remainder of 417.
Use 3 as the next digit of our solution. 
Result so far: 553.0
Deduct 2337 from 2754 and we're left with 417.
Append the next digit (1) from the dividend to 417 and continue with: 4171 / 779

Advancing to step 7:
The number 779 fits into 4171 5 times, leaving a remainder of 276.
Put 5 as the next digit of the answer. 
Result so far: 5535.0
If we take 3895 away from 4171, we end up with 276.
Append the next digit (2) from the dividend to 276 and continue with: 2762 / 779

Let's proceed to step 8:
2762 divided by 779 is 3 with a remainder of 425.
The number 3 becomes the next digit in our result. 
Result so far: 55353.0
If we subtract 2337 from 2762, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Advancing to step 9:
When dividing 4250 by 779, we get 5 with a remainder of 355.
The next digit of our result is 5. 
Result so far: 55353.5
If we subtract 3895 from 4250, we get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 10:
If we divide 3550 by 779, we get 4 and a remainder of 434.
Put 4 as the next digit of the answer. 
Result so far: 55353.54
Subtracting 3116 from 3550 leaves us with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 11:
When dividing 4340 by 779, we get 5 with a remainder of 445.
Use 5 as the next digit of our solution. 
Result so far: 55353.545
Subtracting 3895 from 4340 leaves us with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 12:
4450 divided by 779 is 5 with a remainder of 555.
The next digit of our result is 5. 
Result so far: 55353.5455
Subtract 3895 from 4450 to get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

After the division, we end up with 55353.5455 and a remainder of 0.00555.
