933917 ÷ 7 
The aim is to understand the frequency of 7 in 933917.

Step 1:
The number 7 fits into 9 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 7 from 9.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 7

Step 2:
23 divided by 7 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 2 after subtracting 21 from 23.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 7

Moving on to step 3:
If we divide 23 by 7, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 133.0
Subtract 21 from 23 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 7

Step 4:
The number 7 fits into 29 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 1334.0
Subtract 28 from 29 to get 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 7

Moving on to step 5:
If we divide 11 by 7, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 13341.0
If we subtract 7 from 11, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 7

Moving on to step 6:
7 goes into 47 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 133416.0
Subtract 42 from 47 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.

Going ahead to step 7:
7 goes into 50 7 times with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 133416.7
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.

Step 8:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 133416.71
If we subtract 7 from 10, we 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.

Going ahead to step 9:
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: 133416.714
If we take 28 away from 30, we end up 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:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 133416.7142
Deduct 14 from 20 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.

Step 11:
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: 133416.71428
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.

Going ahead to step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 133416.714285
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.

On to step 13:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 133416.7142857
Subtract 49 from 50 to 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.

Advancing to step 14:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 133416.71428571
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.

The final result is 133416.71428571 with a remainder of 3e-09.
