Let's divide 828549 by 7
The aim is to understand the frequency of 7 in 828549.

Moving on to step 1:
The number 7 fits into 8 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 7 from 8 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 7

Step 2:
When dividing 12 by 7, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 7 from 12, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 7

On to step 3:
If we divide 58 by 7, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 118.0
Deduct 56 from 58 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 7

Going ahead to step 4:
7 can be fit into 25 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1183.0
Deduct 21 from 25 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

Going ahead to step 5:
When dividing 44 by 7, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 11836.0
Deduct 42 from 44 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 7

Moving on to step 6:
7 goes into 29 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 118364.0
If we take 28 away from 29, 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.

Going ahead to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 118364.1
Deduct 7 from 10 and we're left 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.

On to step 8:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 118364.14
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:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 118364.142
If we subtract 14 from 20, we get 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 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 118364.1428
If we take 56 away from 60, we end up 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.

On to step 11:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 118364.14285
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.

Step 12:
When dividing 50 by 7, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 118364.142857
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.

Moving on to step 13:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 118364.1428571
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.

Step 14:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 118364.14285714
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.

Our division results in 118364.14285714 with a remaining 2e-09.
