We look at the division of 955645 by 7 
The aim is to understand the frequency of 7 in 955645.

Moving on to step 1:
When dividing 9 by 7, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 7 from 9 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 7

Going ahead to step 2:
If we divide 25 by 7, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 21 from 25 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 7

Going ahead to step 3:
7 can be fit into 45 6 times, resulting in a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Subtracting 42 from 45 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 7

Step 4:
The number 7 fits into 36 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 1365.0
Deduct 35 from 36 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 7

Moving on to step 5:
14 divided by 7 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 13652.0
If we take 14 away from 14, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 7

Step 6:
5 divided by 7 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 136520.0
Deduct 0 from 5 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.

On to step 7:
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: 136520.7
The remainder is 1 after subtracting 49 from 50.
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 8:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 136520.71
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.

On to step 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 136520.714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 136520.7142
If we subtract 14 from 20, we 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.

Let's proceed to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 136520.71428
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.

Let's proceed to step 12:
7 goes into 40 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 136520.714285
Subtracting 35 from 40 leaves us 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.

Going ahead to step 13:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 136520.7142857
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.

Advancing to step 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 136520.71428571
Subtracting 7 from 10 leaves us 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.

The final result is 136520.71428571 with a remainder of 3e-09.
