We're dividing 48828112 by 7 
The aim is to understand the frequency of 7 in 48828112.

Let's proceed to step 1:
7 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 7

Let's proceed to step 2:
When dividing 48 by 7, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 42 from 48 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

Going ahead to step 3:
When dividing 68 by 7, we get 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 63 from 68 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 7

Moving on to step 4:
The number 7 fits into 52 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 697.0
Subtract 49 from 52 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 7

Moving on to step 5:
7 can be fit into 38 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 6975.0
The remainder is 3 after subtracting 35 from 38.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 7

On to step 6:
7 goes into 31 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 69754.0
Subtracting 28 from 31 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 7

Going ahead to step 7:
7 goes into 31 4 times with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 697544.0
Subtract 28 from 31 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 7

Going ahead to step 8:
32 divided by 7 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 6975444.0
Deduct 28 from 32 and we're left 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 9:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 6975444.5
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.

Advancing to step 10:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 6975444.57
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.

Moving on to step 11:
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: 6975444.571
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.

On to step 12:
7 goes into 30 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 6975444.5714
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.

Step 13:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 6975444.57142
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 14:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 6975444.571428
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.

Step 15:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6975444.5714285
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.

Advancing to step 16:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 6975444.57142857
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.

After the division, we end up with 6975444.57142857 and a remainder of 1e-09.
