We're dividing 12338245 by 778 
The aim is to understand the frequency of 778 in 12338245.

Advancing to step 1:
If we divide 1 by 778, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 778

Step 2:
778 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 778

Going ahead to step 3:
When dividing 123 by 778, we get 0 with a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Fetch the next digit (3) from the dividend, attach it to 123 and continue: 1233 / 778

Moving on to step 4:
If we divide 1233 by 778, we get 1 and a remainder of 455.
The next digit of our result is 1. 
Result so far: 1.0
If we take 778 away from 1233, we end up with 455.
Fetch the next digit (8) from the dividend, attach it to 455 and continue: 4558 / 778

Advancing to step 5:
778 goes into 4558 5 times with a remainder of 668.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 3890 from 4558 and we're left with 668.
Take the next digit (2) from the dividend and append it to 668, then repeat: 6682 / 778

Advancing to step 6:
If we divide 6682 by 778, we get 8 and a remainder of 458.
The number 8 becomes the next digit in our result. 
Result so far: 158.0
The remainder is 458 after subtracting 6224 from 6682.
Include the next digit (4) from the dividend after 458, then repeat: 4584 / 778

Going ahead to step 7:
If we divide 4584 by 778, we get 5 and a remainder of 694.
The next digit of our result is 5. 
Result so far: 1585.0
Deduct 3890 from 4584 and we're left with 694.
Take the next digit (5) from the dividend and append it to 694, then repeat: 6945 / 778

Moving on to step 8:
6945 divided by 778 is 8 with a remainder of 721.
Record the quotient 8 as the next digit in the result. 
Result so far: 15858.0
The remainder is 721 after subtracting 6224 from 6945.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Let's proceed to step 9:
778 goes into 7210 9 times with a remainder of 208.
The number 9 becomes the next digit in our result. 
Result so far: 15858.9
If we take 7002 away from 7210, we end up with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 10:
778 goes into 2080 2 times with a remainder of 524.
Write down 2 as next digit of the result. 
Result so far: 15858.92
Deduct 1556 from 2080 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Going ahead to step 11:
778 goes into 5240 6 times with a remainder of 572.
Record the quotient 6 as the next digit in the result. 
Result so far: 15858.926
Deduct 4668 from 5240 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 12:
778 goes into 5720 7 times with a remainder of 274.
Record the quotient 7 as the next digit in the result. 
Result so far: 15858.9267
If we subtract 5446 from 5720, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 13:
The number 778 fits into 2740 3 times, leaving a remainder of 406.
Put 3 as the next digit of the answer. 
Result so far: 15858.92673
If we take 2334 away from 2740, we end up with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Advancing to step 14:
The number 778 fits into 4060 5 times, leaving a remainder of 170.
Write down 5 as next digit of the result. 
Result so far: 15858.926735
Subtract 3890 from 4060 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 15:
1700 divided by 778 is 2 with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 15858.9267352
If we subtract 1556 from 1700, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 16:
1440 divided by 778 is 1 with a remainder of 662.
Use 1 as the next digit of our solution. 
Result so far: 15858.92673521
If we take 778 away from 1440, we end up with 662.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6620, and continue the process.

The final outcome is 15858.92673521, with a leftover of 6.62e-07.
