We're dividing 16360379 by 7 
The aim is to understand the frequency of 7 in 16360379.

Going ahead to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 7

Moving on to step 2:
16 divided by 7 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 14 away from 16, we end up with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 7

Step 3:
When dividing 23 by 7, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtract 21 from 23 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 7

On to step 4:
The number 7 fits into 26 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 233.0
Subtract 21 from 26 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 7

Step 5:
If we divide 50 by 7, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 2337.0
The remainder is 1 after subtracting 49 from 50.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 7

Moving on to step 6:
If we divide 13 by 7, we get 1 and a remainder of 6.
The next digit of our result is 1. 
Result so far: 23371.0
Subtract 7 from 13 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 7

Going ahead to step 7:
When dividing 67 by 7, we get 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 233719.0
If we subtract 63 from 67, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 7

Going ahead to step 8:
49 divided by 7 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 2337197.0
Subtract 49 from 49 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 7 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2337197.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2337197.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 2337197.0 with a remainder of 0.0.
