Let's divide 115616 by 7
The aim is to understand the frequency of 7 in 115616.

Moving on to step 1:
The number 7 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 7

Moving on to step 2:
7 can be fit into 11 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 7 away from 11, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 7

Advancing to step 3:
When dividing 45 by 7, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 42 from 45, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 7

Advancing to step 4:
When dividing 36 by 7, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 165.0
The remainder is 1 after subtracting 35 from 36.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 7

Moving on to step 5:
The number 7 fits into 11 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1651.0
Deduct 7 from 11 and we're left with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 7

On to step 6:
When dividing 46 by 7, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 16516.0
Deduct 42 from 46 and we're left with 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 7:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 16516.5
If we take 35 away from 40, we end up 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 8:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 16516.57
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 16516.571
Deduct 7 from 10 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 16516.5714
If we take 28 away from 30, we end up 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.

Moving on to step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 16516.57142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 16516.571428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 16516.5714285
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 16516.57142857
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 16516.57142857, with a leftover of 1e-09.
