180132 divided by 7 
The aim is to understand the frequency of 7 in 180132.

Going ahead to step 1:
1 divided by 7 is 0 with 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.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 7

Going ahead to step 2:
7 goes into 18 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 14 away from 18, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 7

Let's proceed to step 3:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 35 from 40 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 7

Advancing to step 4:
7 can be fit into 51 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
If we take 49 away from 51, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 7

Moving on to step 5:
When dividing 23 by 7, we get 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 2573.0
Subtracting 21 from 23 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 7

Advancing to step 6:
The number 7 fits into 22 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 25733.0
Subtracting 21 from 22 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.

Going ahead to step 7:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 25733.1
If we take 7 away from 10, we end up 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.

Advancing to step 8:
30 divided by 7 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 25733.14
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.

Advancing to step 9:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 25733.142
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.

Advancing to step 10:
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: 25733.1428
Subtracting 56 from 60 leaves us 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.

Step 11:
When dividing 40 by 7, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 25733.14285
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.

Moving on to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 25733.142857
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 13:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 25733.1428571
Subtract 7 from 10 to 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.

Moving on to step 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 25733.14285714
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.

The quotient of the division is 25733.14285714, and the remainder is 2e-09.
