We look at the division of 7375807 by 778 
The aim is to understand the frequency of 778 in 7375807.

Going ahead to step 1:
If we divide 7 by 778, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 778

Advancing to step 2:
778 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Take the next digit (7) from the dividend and append it to 73, then repeat: 737 / 778

Step 3:
737 divided by 778 is 0 with a remainder of 737.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 737 after subtracting 0 from 737.
Fetch the next digit (5) from the dividend, attach it to 737 and continue: 7375 / 778

Going ahead to step 4:
When dividing 7375 by 778, we get 9 with a remainder of 373.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 7002 from 7375 leaves us with 373.
Fetch the next digit (8) from the dividend, attach it to 373 and continue: 3738 / 778

Advancing to step 5:
When dividing 3738 by 778, we get 4 with a remainder of 626.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 3112 from 3738 leaves us with 626.
Append the next digit (0) from the dividend to 626 and continue with: 6260 / 778

Advancing to step 6:
When dividing 6260 by 778, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 948.0
If we take 6224 away from 6260, we end up with 36.
Append the next digit (7) from the dividend to 36 and continue with: 367 / 778

Advancing to step 7:
If we divide 367 by 778, we get 0 and a remainder of 367.
Record the quotient 0 as the next digit in the result. 
Result so far: 9480.0
Subtracting 0 from 367 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 8:
3670 divided by 778 is 4 with a remainder of 558.
The next digit of our result is 4. 
Result so far: 9480.4
If we subtract 3112 from 3670, we get 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 9:
The number 778 fits into 5580 7 times, leaving a remainder of 134.
Write down 7 as next digit of the result. 
Result so far: 9480.47
If we subtract 5446 from 5580, we get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
When dividing 1340 by 778, we get 1 with a remainder of 562.
The next digit of our result is 1. 
Result so far: 9480.471
Subtracting 778 from 1340 leaves us with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 11:
778 can be fit into 5620 7 times, resulting in a remainder of 174.
Put 7 as the next digit of the answer. 
Result so far: 9480.4717
Subtracting 5446 from 5620 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 12:
When dividing 1740 by 778, we get 2 with a remainder of 184.
The next digit of our result is 2. 
Result so far: 9480.47172
Subtracting 1556 from 1740 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 13:
778 can be fit into 1840 2 times, resulting in a remainder of 284.
The next digit of our result is 2. 
Result so far: 9480.471722
Subtracting 1556 from 1840 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 9480.471722 with a balance of 2.84e-05.
