888473 divided by 7 
The aim is to understand the frequency of 7 in 888473.

Step 1:
8 divided by 7 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 7

Let's proceed to step 2:
18 divided by 7 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 4 after subtracting 14 from 18.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 7

Step 3:
7 goes into 48 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 42 from 48 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Moving on to step 4:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 1269.0
If we take 63 away from 64, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 7

Step 5:
7 goes into 17 2 times with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12692.0
If we take 14 away from 17, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 7

Moving on to step 6:
The number 7 fits into 33 4 times, leaving a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 126924.0
Deduct 28 from 33 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 7:
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: 126924.7
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.

Step 8:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 126924.71
Subtract 7 from 10 to 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.

Let's proceed to step 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 126924.714
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 10:
20 divided by 7 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 126924.7142
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.

Moving on to step 11:
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: 126924.71428
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.

Advancing to step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 126924.714285
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.

Moving on to step 13:
50 divided by 7 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 126924.7142857
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.

Let's proceed to step 14:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 126924.71428571
Deduct 7 from 10 and we're left 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.

The quotient of the division is 126924.71428571, and the remainder is 3e-09.
