We divide 488606 by 7
The aim is to understand the frequency of 7 in 488606.

On to step 1:
If we divide 4 by 7, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 7

Moving on 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
Subtract 42 from 48 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 7

On to step 3:
The number 7 fits into 68 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 63 from 68 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 7

On to step 4:
56 divided by 7 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 698.0
If we subtract 56 from 56, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 7

Advancing to step 5:
If we divide 0 by 7, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 6980.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 7

Step 6:
When dividing 6 by 7, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 69800.0
If we take 0 away from 6, we end up 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 7:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 69800.8
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.

Going ahead to step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 69800.85
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.

Moving on to step 9:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 69800.857
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.

Going ahead to step 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 69800.8571
The remainder is 3 after subtracting 7 from 10.
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 11:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 69800.85714
Subtract 28 from 30 to 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.

Step 12:
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: 69800.857142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 69800.8571428
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.

On to step 14:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 69800.85714285
If we subtract 35 from 40, we 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.

In conclusion, the division gives 69800.85714285 with a balance of 5e-09.
