575844 ÷ 7 
The aim is to understand the frequency of 7 in 575844.

Let's proceed to step 1:
7 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 7

Going ahead to step 2:
57 divided by 7 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 56 from 57 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 7

Let's proceed to step 3:
15 divided by 7 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Deduct 14 from 15 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Advancing to step 4:
7 can be fit into 18 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 822.0
Subtract 14 from 18 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 7

On to step 5:
7 can be fit into 44 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 8226.0
If we subtract 42 from 44, we get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 7

Moving on to step 6:
If we divide 24 by 7, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 82263.0
Deduct 21 from 24 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 7:
When dividing 30 by 7, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 82263.4
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.

Moving on to step 8:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 82263.42
Subtracting 14 from 20 leaves us 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.

Moving on to step 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 82263.428
Subtracting 56 from 60 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.

Let's proceed to step 10:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 82263.4285
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.

Moving on to step 11:
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: 82263.42857
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.

On to step 12:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 82263.428571
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.

On to step 13:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 82263.4285714
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.

Moving on to step 14:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 82263.42857142
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.

Our division results in 82263.42857142 with a remaining 6e-09.
