973183 ÷ 7 
The aim is to understand the frequency of 7 in 973183.

Let's proceed to step 1:
When dividing 9 by 7, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 7 from 9.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 7

Step 2:
27 divided by 7 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we take 21 away from 27, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 7

Advancing to step 3:
63 divided by 7 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we take 63 away from 63, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 7

Advancing to step 4:
7 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 1390.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 7

On to step 5:
When dividing 18 by 7, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 13902.0
Subtract 14 from 18 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Step 6:
The number 7 fits into 43 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 139026.0
The remainder is 1 after subtracting 42 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 139026.1
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.

Step 8:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 139026.14
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.

Step 9:
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: 139026.142
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 10:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 139026.1428
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.

Let's proceed to step 11:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 139026.14285
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.

Let's proceed to step 12:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 139026.142857
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.

Let's proceed to step 13:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 139026.1428571
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.

Advancing to step 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 139026.14285714
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.

In conclusion, the division gives 139026.14285714 with a balance of 2e-09.
