We look at the division of 8402441 by 778 
The aim is to understand the frequency of 778 in 8402441.

Advancing to step 1:
778 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 778

On to step 2:
When dividing 84 by 778, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 778

On to step 3:
778 can be fit into 840 1 times, resulting in a remainder of 62.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 778 from 840, we get 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 778

Let's proceed to step 4:
When dividing 622 by 778, we get 0 with a remainder of 622.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 622 leaves us with 622.
Append the next digit (4) from the dividend to 622 and continue with: 6224 / 778

Step 5:
When dividing 6224 by 778, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 108.0
The remainder is 0 after subtracting 6224 from 6224.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 778

On to step 6:
778 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 1080.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 778

Advancing to step 7:
When dividing 41 by 778, we get 0 with a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 10800.0
Subtract 0 from 41 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 8:
When dividing 410 by 778, we get 0 with a remainder of 410.
Record the quotient 0 as the next digit in the result. 
Result so far: 10800.0
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Moving on to step 9:
If we divide 4100 by 778, we get 5 and a remainder of 210.
Write down 5 as next digit of the result. 
Result so far: 10800.05
If we subtract 3890 from 4100, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
778 can be fit into 2100 2 times, resulting in a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 10800.052
Subtract 1556 from 2100 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 11:
When dividing 5440 by 778, we get 6 with a remainder of 772.
Record the quotient 6 as the next digit in the result. 
Result so far: 10800.0526
Subtract 4668 from 5440 to get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Moving on to step 12:
If we divide 7720 by 778, we get 9 and a remainder of 718.
Record the quotient 9 as the next digit in the result. 
Result so far: 10800.05269
Subtract 7002 from 7720 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

On to step 13:
778 goes into 7180 9 times with a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 10800.052699
Subtracting 7002 from 7180 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

In conclusion, the division gives 10800.052699 with a balance of 1.78e-05.
