15062291 divided by 7 
The aim is to understand the frequency of 7 in 15062291.

Let's proceed to step 1:
If we divide 1 by 7, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 7

On to step 2:
7 can be fit into 15 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 14 from 15, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 7

Step 3:
If we divide 10 by 7, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 7 from 10 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 7

Advancing to step 4:
When dividing 36 by 7, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
Subtract 35 from 36 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 7

Moving on to step 5:
If we divide 12 by 7, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 2151.0
Subtracting 7 from 12 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 7

Moving on to step 6:
The number 7 fits into 52 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 21517.0
If we subtract 49 from 52, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 7

Going ahead to step 7:
The number 7 fits into 39 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 215175.0
If we take 35 away from 39, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

Moving on to step 8:
When dividing 41 by 7, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 2151755.0
The remainder is 6 after subtracting 35 from 41.
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 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 2151755.8
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.

Advancing to step 10:
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: 2151755.85
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.

Going ahead to step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 2151755.857
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.

On to step 12:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 2151755.8571
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.

Step 13:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 2151755.85714
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.

On to step 14:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 2151755.857142
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.

Moving on to step 15:
7 goes into 60 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 2151755.8571428
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.

Moving on to step 16:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2151755.85714285
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.

After the division, we end up with 2151755.85714285 and a remainder of 5e-09.
