488172 divided by 7 
The aim is to understand the frequency of 7 in 488172.

Moving on to step 1:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 7

Let's proceed to step 2:
7 can be fit into 48 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 6 after subtracting 42 from 48.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 7

Let's proceed to step 3:
68 divided by 7 is 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 63 from 68 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 7

Step 4:
When dividing 51 by 7, we get 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 697.0
Subtract 49 from 51 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 7

Moving on to step 5:
When dividing 27 by 7, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 6973.0
Deduct 21 from 27 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 7

Moving on to step 6:
62 divided by 7 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 69738.0
Subtracting 56 from 62 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 7:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 69738.8
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.

On to step 8:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 69738.85
If we take 35 away from 40, we end up 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.

On to step 9:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 69738.857
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 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 69738.8571
If we take 7 away from 10, we end up 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.

Going ahead to step 11:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 69738.85714
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 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 69738.857142
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.

Going ahead to step 13:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 69738.8571428
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.

Moving on to step 14:
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: 69738.85714285
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.

The quotient of the division is 69738.85714285, and the remainder is 5e-09.
