We look at the division of 78008300 by 778 
The aim is to understand the frequency of 778 in 78008300.

Going ahead to step 1:
When dividing 7 by 778, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 778

Moving on to step 2:
When dividing 78 by 778, we get 0 with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 778

Step 3:
778 goes into 780 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 778 from 780 and we're left with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 778

Let's proceed to step 4:
When dividing 20 by 778, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 20 after subtracting 0 from 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 778

Going ahead to step 5:
778 goes into 208 0 times with a remainder of 208.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 208, we get 208.
Grab the next digit (3) from the dividend, add it to 208, then carry on: 2083 / 778

Let's proceed to step 6:
778 goes into 2083 2 times with a remainder of 527.
Use 2 as the next digit of our solution. 
Result so far: 1002.0
Subtract 1556 from 2083 to get 527.
Append the next digit (0) from the dividend to 527 and continue with: 5270 / 778

Let's proceed to step 7:
If we divide 5270 by 778, we get 6 and a remainder of 602.
The next digit of our result is 6. 
Result so far: 10026.0
If we subtract 4668 from 5270, we get 602.
Append the next digit (0) from the dividend to 602 and continue with: 6020 / 778

Advancing to step 8:
778 can be fit into 6020 7 times, resulting in a remainder of 574.
The number 7 becomes the next digit in our result. 
Result so far: 100267.0
Subtract 5446 from 6020 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 9:
5740 divided by 778 is 7 with a remainder of 294.
Use 7 as the next digit of our solution. 
Result so far: 100267.7
The remainder is 294 after subtracting 5446 from 5740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Going ahead to step 10:
The number 778 fits into 2940 3 times, leaving a remainder of 606.
Use 3 as the next digit of our solution. 
Result so far: 100267.73
Deduct 2334 from 2940 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Going ahead to step 11:
778 can be fit into 6060 7 times, resulting in a remainder of 614.
The number 7 becomes the next digit in our result. 
Result so far: 100267.737
If we take 5446 away from 6060, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 12:
The number 778 fits into 6140 7 times, leaving a remainder of 694.
The number 7 becomes the next digit in our result. 
Result so far: 100267.7377
Subtracting 5446 from 6140 leaves us with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Our division results in 100267.7377 with a remaining 0.00694.
