We divide 910233 by 7
The aim is to understand the frequency of 7 in 910233.

Step 1:
7 goes into 9 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 7 from 9 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 7

On to step 2:
7 goes into 21 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 0 after subtracting 21 from 21.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 7

Advancing to step 3:
7 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtract 0 from 0 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 7

Moving on to step 4:
When dividing 2 by 7, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 1300.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 7

Let's proceed to step 5:
7 can be fit into 23 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 13003.0
Subtract 21 from 23 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 7

On to step 6:
7 goes into 23 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 130033.0
The remainder is 2 after subtracting 21 from 23.
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 7:
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: 130033.2
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.

Going ahead to step 8:
60 divided by 7 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 130033.28
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.

Advancing to step 9:
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: 130033.285
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.

Step 10:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 130033.2857
Deduct 49 from 50 and we're left 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.

Let's proceed to step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 130033.28571
If we take 7 away from 10, 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.

On to step 12:
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: 130033.285714
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.

Advancing to step 13:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 130033.2857142
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 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 130033.28571428
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.

The quotient of the division is 130033.28571428, and the remainder is 4e-09.
