709973 ÷ 7 
The aim is to understand the frequency of 7 in 709973.

Going ahead to step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 7

Let's proceed to step 2:
When dividing 0 by 7, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Going ahead to step 3:
7 goes into 9 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 101.0
Subtracting 7 from 9 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 7

On to step 4:
7 can be fit into 29 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 1014.0
Subtract 28 from 29 to get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 7

Step 5:
If we divide 17 by 7, we get 2 and a remainder of 3.
The next digit of our result is 2. 
Result so far: 10142.0
Subtracting 14 from 17 leaves us with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 7

Step 6:
33 divided by 7 is 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 101424.0
Subtracting 28 from 33 leaves us 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.

Step 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 101424.7
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 8:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 101424.71
Subtracting 7 from 10 leaves us 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.

On to step 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 101424.714
If we take 28 away from 30, we end up 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.

Advancing to step 10:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 101424.7142
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.

Going ahead to step 11:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 101424.71428
Deduct 56 from 60 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.

Moving on to step 12:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 101424.714285
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.

Advancing to step 13:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 101424.7142857
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.

Moving on to step 14:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 101424.71428571
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.

The quotient of the division is 101424.71428571, and the remainder is 3e-09.
