We're dividing 461423 by 7 
The aim is to understand the frequency of 7 in 461423.

On to step 1:
If we divide 4 by 7, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 7

Step 2:
The number 7 fits into 46 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 42 from 46 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

On to step 3:
The number 7 fits into 41 5 times, leaving a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 35 from 41 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Let's proceed to step 4:
64 divided by 7 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 659.0
If we subtract 63 from 64, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 7

Moving on to step 5:
The number 7 fits into 12 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 6591.0
Subtract 7 from 12 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 7

Step 6:
If we divide 53 by 7, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 65917.0
Subtracting 49 from 53 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.

Going ahead to step 7:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 65917.5
The remainder is 5 after subtracting 35 from 40.
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 8:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 65917.57
Subtract 49 from 50 to 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.

On to step 9:
7 goes into 10 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 65917.571
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 10:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 65917.5714
Subtract 28 from 30 to 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 11:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 65917.57142
The remainder is 6 after subtracting 14 from 20.
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 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 65917.571428
Subtract 56 from 60 to get 4.
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 13:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 65917.5714285
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.

Going ahead to step 14:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 65917.57142857
If we subtract 49 from 50, 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.

The final result is 65917.57142857 with a remainder of 1e-09.
