Let's divide 25475 by 7
The aim is to understand the frequency of 7 in 25475.

On to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 7

Going ahead to step 2:
7 goes into 25 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 21 from 25, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

Moving on to step 3:
7 can be fit into 44 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 42 from 44 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 7

Going ahead to step 4:
The number 7 fits into 27 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 363.0
The remainder is 6 after subtracting 21 from 27.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 7

On to step 5:
7 goes into 65 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 3639.0
The remainder is 2 after subtracting 63 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 6:
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: 3639.2
Subtract 14 from 20 to 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.

Going ahead to step 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 3639.28
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.

Let's proceed to step 8:
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: 3639.285
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 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 3639.2857
Subtracting 49 from 50 leaves us 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 10:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 3639.28571
If we subtract 7 from 10, we 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 11:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 3639.285714
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.

Let's proceed to step 12:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 3639.2857142
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.

On to step 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 3639.28571428
If we subtract 56 from 60, we 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.

In conclusion, the division gives 3639.28571428 with a balance of 4e-09.
