We look at the division of 78914023 by 775 
The aim is to understand the frequency of 775 in 78914023.

Let's proceed to step 1:
775 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 775

On to step 2:
When dividing 78 by 775, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 775

Step 3:
775 can be fit into 789 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 14 after subtracting 775 from 789.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 775

Going ahead to step 4:
The number 775 fits into 141 0 times, leaving a remainder of 141.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 141, we end up with 141.
Include the next digit (4) from the dividend after 141, then repeat: 1414 / 775

Advancing to step 5:
If we divide 1414 by 775, we get 1 and a remainder of 639.
Put 1 as the next digit of the answer. 
Result so far: 101.0
Subtract 775 from 1414 to get 639.
Fetch the next digit (0) from the dividend, attach it to 639 and continue: 6390 / 775

On to step 6:
When dividing 6390 by 775, we get 8 with a remainder of 190.
Record the quotient 8 as the next digit in the result. 
Result so far: 1018.0
Subtract 6200 from 6390 to get 190.
Grab the next digit (2) from the dividend, add it to 190, then carry on: 1902 / 775

On to step 7:
The number 775 fits into 1902 2 times, leaving a remainder of 352.
The next digit of our result is 2. 
Result so far: 10182.0
Subtract 1550 from 1902 to get 352.
Take the next digit (3) from the dividend and append it to 352, then repeat: 3523 / 775

Going ahead to step 8:
If we divide 3523 by 775, we get 4 and a remainder of 423.
Put 4 as the next digit of the answer. 
Result so far: 101824.0
If we subtract 3100 from 3523, we get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Let's proceed to step 9:
775 goes into 4230 5 times with a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 101824.5
Subtracting 3875 from 4230 leaves us with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

On to step 10:
775 can be fit into 3550 4 times, resulting in a remainder of 450.
Record the quotient 4 as the next digit in the result. 
Result so far: 101824.54
If we subtract 3100 from 3550, we get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Moving on to step 11:
4500 divided by 775 is 5 with a remainder of 625.
The next digit of our result is 5. 
Result so far: 101824.545
Deduct 3875 from 4500 and we're left with 625.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6250, and continue the process.

Step 12:
6250 divided by 775 is 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 101824.5458
Subtracting 6200 from 6250 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 13:
If we divide 500 by 775, we get 0 and a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 101824.5458
Subtract 0 from 500 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Moving on to step 14:
5000 divided by 775 is 6 with a remainder of 350.
The number 6 becomes the next digit in our result. 
Result so far: 101824.545806
Subtract 4650 from 5000 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 15:
The number 775 fits into 3500 4 times, leaving a remainder of 400.
Write down 4 as next digit of the result. 
Result so far: 101824.5458064
Deduct 3100 from 3500 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 16:
4000 divided by 775 is 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 101824.54580645
Deduct 3875 from 4000 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

After the division, we end up with 101824.54580645 and a remainder of 1.25e-07.
