Let's divide 777619 by 7
The aim is to understand the frequency of 7 in 777619.

Advancing to step 1:
If we divide 7 by 7, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 7 from 7 to get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 7

Step 2:
When dividing 7 by 7, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtract 7 from 7 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 7

Going ahead to step 3:
7 divided by 7 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 111.0
The remainder is 0 after subtracting 7 from 7.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 7

Let's proceed to step 4:
6 divided by 7 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 1110.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 7

Advancing to step 5:
When dividing 61 by 7, we get 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 11108.0
Subtracting 56 from 61 leaves us with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 7

Advancing to step 6:
7 can be fit into 59 8 times, resulting in a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 111088.0
If we subtract 56 from 59, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
7 goes into 30 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 111088.4
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 111088.42
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 111088.428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 111088.4285
Deduct 35 from 40 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 111088.42857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 111088.428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 111088.4285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 111088.42857142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 111088.42857142 with a remaining 6e-09.
