851316 divided by 7 
The aim is to understand the frequency of 7 in 851316.

Going ahead to step 1:
8 divided by 7 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 7

Moving on to step 2:
7 can be fit into 15 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 14 from 15, we get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 7

Let's proceed to step 3:
7 can be fit into 11 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 121.0
Deduct 7 from 11 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 7

Going ahead to step 4:
If we divide 43 by 7, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 1216.0
The remainder is 1 after subtracting 42 from 43.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 7

Going ahead to step 5:
7 can be fit into 11 1 times, resulting in a remainder of 4.
The next digit of our result is 1. 
Result so far: 12161.0
Subtract 7 from 11 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 7

Advancing to step 6:
7 goes into 46 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 121616.0
Subtracting 42 from 46 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.

Moving on to step 7:
7 goes into 40 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 121616.5
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:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 121616.57
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.

Step 9:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 121616.571
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 10:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 121616.5714
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 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 121616.57142
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.

Step 12:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 121616.571428
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.

Step 13:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 121616.5714285
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.

On to step 14:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 121616.57142857
If we take 49 away from 50, 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.

The quotient of the division is 121616.57142857, and the remainder is 1e-09.
