814171 divided by 7 
The aim is to understand the frequency of 7 in 814171.

On to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 7 from 8 to get 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.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 4 after subtracting 7 from 11.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 7

Going ahead to step 3:
7 can be fit into 44 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we subtract 42 from 44, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 7

Let's proceed to step 4:
When dividing 21 by 7, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 1163.0
Deduct 21 from 21 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 7

Let's proceed to step 5:
When dividing 7 by 7, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 11631.0
If we take 7 away from 7, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 7

Moving on to step 6:
If we divide 1 by 7, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 116310.0
If we subtract 0 from 1, we 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.

Advancing to step 7:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 116310.1
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.

Going ahead to step 8:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 116310.14
Deduct 28 from 30 and we're left 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.

Going ahead to step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 116310.142
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.

Let's proceed to step 10:
60 divided by 7 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 116310.1428
Deduct 56 from 60 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 11:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 116310.14285
Deduct 35 from 40 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.

Advancing to step 12:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 116310.142857
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.

Step 13:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 116310.1428571
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.

Let's proceed to step 14:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 116310.14285714
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.

The final result is 116310.14285714 with a remainder of 2e-09.
