488476 divided by 7 
The aim is to understand the frequency of 7 in 488476.

Advancing to step 1:
When dividing 4 by 7, we get 0 with 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.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 7

Advancing to step 2:
The number 7 fits into 48 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 42 from 48, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 7

Step 3:
68 divided by 7 is 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.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 7

On to step 4:
When dividing 54 by 7, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 697.0
If we take 49 away from 54, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 7

Moving on to step 5:
If we divide 57 by 7, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 6978.0
If we take 56 away from 57, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 7

Step 6:
7 goes into 16 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 69782.0
Deduct 14 from 16 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.

Let's proceed to step 7:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 69782.2
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 8:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 69782.28
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.

Let's proceed to step 9:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 69782.285
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.

Going ahead to step 10:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 69782.2857
The remainder is 1 after subtracting 49 from 50.
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:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 69782.28571
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.

Step 12:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 69782.285714
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 13:
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: 69782.2857142
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.

Step 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 69782.28571428
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.

The quotient of the division is 69782.28571428, and the remainder is 4e-09.
