69370262 ÷ 7 
The aim is to understand the frequency of 7 in 69370262.

On to step 1:
When dividing 6 by 7, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 7

Going ahead to step 2:
When dividing 69 by 7, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 63 from 69 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 7

Let's proceed to step 3:
7 goes into 63 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 63 from 63 leaves us with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 7

Going ahead to step 4:
7 can be fit into 7 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 991.0
If we subtract 7 from 7, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 7

Let's proceed to step 5:
7 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9910.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 7

Going ahead to step 6:
If we divide 2 by 7, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 99100.0
Subtract 0 from 2 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 7

Step 7:
7 can be fit into 26 3 times, resulting in a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 991003.0
Subtracting 21 from 26 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 7

Advancing to step 8:
The number 7 fits into 52 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 9910037.0
If we take 49 away from 52, 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.

Advancing to step 9:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 9910037.4
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.

On to step 10:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 9910037.42
Subtracting 14 from 20 leaves us 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.

Let's proceed to step 11:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 9910037.428
The remainder is 4 after subtracting 56 from 60.
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 12:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9910037.4285
Subtracting 35 from 40 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 13:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 9910037.42857
If we subtract 49 from 50, we 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.

Step 14:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 9910037.428571
The remainder is 3 after subtracting 7 from 10.
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 15:
30 divided by 7 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 9910037.4285714
Subtracting 28 from 30 leaves us 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.

Moving on to step 16:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 9910037.42857142
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.

After the division, we end up with 9910037.42857142 and a remainder of 6e-09.
