We divide 144502 by 7
The aim is to understand the frequency of 7 in 144502.

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
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 7

On to step 2:
The number 7 fits into 14 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 14 from 14 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 7

Moving on to step 3:
7 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 20.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 7

Moving on to step 4:
7 goes into 45 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 206.0
If we subtract 42 from 45, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 7

Advancing to step 5:
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: 2064.0
Subtract 28 from 30 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 7

Advancing to step 6:
If we divide 22 by 7, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 20643.0
If we take 21 away from 22, we end up 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 7:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 20643.1
If we subtract 7 from 10, 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.

On to step 8:
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: 20643.14
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.

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: 20643.142
Deduct 14 from 20 and we're left 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.
The next digit of our result is 8. 
Result so far: 20643.1428
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.

On to step 11:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 20643.14285
Subtract 35 from 40 to 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.

Advancing to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 20643.142857
Deduct 49 from 50 and we're left 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 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 20643.1428571
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.

Step 14:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 20643.14285714
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.

The final outcome is 20643.14285714, with a leftover of 2e-09.
