84623608 divided by 7 
The aim is to understand the frequency of 7 in 84623608.

On to step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 7 from 8, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 7

Advancing to step 2:
7 can be fit into 14 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 14 from 14 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 7

Moving on to step 3:
6 divided by 7 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 120.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 7

On to step 4:
7 can be fit into 62 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 1208.0
If we subtract 56 from 62, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 7

Going ahead to step 5:
7 goes into 63 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 12089.0
Subtract 63 from 63 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 7

On to step 6:
7 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 120890.0
If we subtract 0 from 6, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 7

Moving on to step 7:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1208908.0
If we take 56 away from 60, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 7

Moving on to step 8:
The number 7 fits into 48 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 12089086.0
The remainder is 6 after subtracting 42 from 48.
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 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 12089086.8
If we take 56 away from 60, we end up 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 10:
If we divide 40 by 7, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12089086.85
Subtract 35 from 40 to 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.

Let's proceed to step 11:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 12089086.857
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.

Advancing to step 12:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 12089086.8571
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.

Moving on to step 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 12089086.85714
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.

Advancing to step 14:
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: 12089086.857142
Subtract 14 from 20 to get 6.
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 15:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 12089086.8571428
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.

Going ahead to step 16:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 12089086.85714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 12089086.85714285, with a leftover of 5e-09.
