We divide 73122754 by 7
The aim is to understand the frequency of 7 in 73122754.

Advancing to step 1:
7 goes into 7 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 7

Step 2:
7 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 7

Let's proceed to step 3:
7 can be fit into 31 4 times, resulting in a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we subtract 28 from 31, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 7

Moving on to step 4:
7 can be fit into 32 4 times, resulting in a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 1044.0
Subtract 28 from 32 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 7

Let's proceed to step 5:
7 goes into 42 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 10446.0
If we take 42 away from 42, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 7

Going ahead to step 6:
7 divided by 7 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 104461.0
If we subtract 7 from 7, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 7

Let's proceed to step 7:
The number 7 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 1044610.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 7

Moving on to step 8:
7 goes into 54 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 10446107.0
The remainder is 5 after subtracting 49 from 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 10446107.7
If we take 49 away from 50, we end up 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.

Advancing to step 10:
10 divided by 7 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 10446107.71
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.

Advancing to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 10446107.714
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.

Let's proceed to step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 10446107.7142
If we take 14 away from 20, we end up 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.

Step 13:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10446107.71428
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.

On to step 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 10446107.714285
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.

Advancing to step 15:
When dividing 50 by 7, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 10446107.7142857
If we take 49 away from 50, we end up 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.

Going ahead to step 16:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 10446107.71428571
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.

The final outcome is 10446107.71428571, with a leftover of 3e-09.
