We're dividing 973587 by 7 
The aim is to understand the frequency of 7 in 973587.

Advancing to step 1:
When dividing 9 by 7, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 7 away from 9, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 7

Moving on to step 2:
The number 7 fits into 27 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 21 away from 27, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 7

On to step 3:
If we divide 63 by 7, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 139.0
If we subtract 63 from 63, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 7

Advancing to step 4:
If we divide 5 by 7, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 1390.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 7

Let's proceed to step 5:
58 divided by 7 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 13908.0
If we take 56 away from 58, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 7

On to step 6:
7 can be fit into 27 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 139083.0
Deduct 21 from 27 and we're left 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 next digit of our result is 8. 
Result so far: 139083.8
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.

Advancing to step 8:
7 goes into 40 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 139083.85
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.

Advancing to step 9:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 139083.857
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.

Moving on to step 10:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 139083.8571
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.

Let's proceed to step 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 139083.85714
Subtract 28 from 30 to 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.

On to step 12:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 139083.857142
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.

On to step 13:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 139083.8571428
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.

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: 139083.85714285
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.

After the division, we end up with 139083.85714285 and a remainder of 5e-09.
