We look at the division of 7782218 by 774 
The aim is to understand the frequency of 774 in 7782218.

Going ahead to step 1:
7 divided by 774 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 774

Advancing to step 2:
774 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 774

Let's proceed to step 3:
If we divide 778 by 774, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 774 from 778 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 774

On to step 4:
774 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 774

Moving on to step 5:
422 divided by 774 is 0 with a remainder of 422.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 422 after subtracting 0 from 422.
Append the next digit (1) from the dividend to 422 and continue with: 4221 / 774

Going ahead to step 6:
774 can be fit into 4221 5 times, resulting in a remainder of 351.
The next digit of our result is 5. 
Result so far: 1005.0
If we take 3870 away from 4221, we end up with 351.
Fetch the next digit (8) from the dividend, attach it to 351 and continue: 3518 / 774

Advancing to step 7:
774 can be fit into 3518 4 times, resulting in a remainder of 422.
Use 4 as the next digit of our solution. 
Result so far: 10054.0
Deduct 3096 from 3518 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 8:
774 can be fit into 4220 5 times, resulting in a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 10054.5
Subtract 3870 from 4220 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.

Step 9:
The number 774 fits into 3500 4 times, leaving a remainder of 404.
The number 4 becomes the next digit in our result. 
Result so far: 10054.54
The remainder is 404 after subtracting 3096 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Going ahead to step 10:
774 goes into 4040 5 times with a remainder of 170.
The number 5 becomes the next digit in our result. 
Result so far: 10054.545
If we take 3870 away from 4040, we end up with 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 11:
774 goes into 1700 2 times with a remainder of 152.
Write down 2 as next digit of the result. 
Result so far: 10054.5452
If we take 1548 away from 1700, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 12:
If we divide 1520 by 774, we get 1 and a remainder of 746.
The number 1 becomes the next digit in our result. 
Result so far: 10054.54521
If we subtract 774 from 1520, we get 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Let's proceed to step 13:
When dividing 7460 by 774, we get 9 with a remainder of 494.
Put 9 as the next digit of the answer. 
Result so far: 10054.545219
If we take 6966 away from 7460, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Going ahead to step 14:
The number 774 fits into 4940 6 times, leaving a remainder of 296.
The number 6 becomes the next digit in our result. 
Result so far: 10054.5452196
If we subtract 4644 from 4940, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 15:
If we divide 2960 by 774, we get 3 and a remainder of 638.
The number 3 becomes the next digit in our result. 
Result so far: 10054.54521963
The remainder is 638 after subtracting 2322 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

After the division, we end up with 10054.54521963 and a remainder of 6.38e-07.
