916558 divided by 7 
The aim is to understand the frequency of 7 in 916558.

On to step 1:
9 divided by 7 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 7 from 9 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 7

Let's proceed to step 2:
When dividing 21 by 7, we get 3 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.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 7

Going ahead to step 3:
7 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 130.0
If we subtract 0 from 6, we get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 7

Advancing to step 4:
If we divide 65 by 7, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 1309.0
Subtracting 63 from 65 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 7

Going ahead to step 5:
7 goes into 25 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 13093.0
Subtract 21 from 25 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 7

On to step 6:
If we divide 48 by 7, we get 6 and a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 130936.0
Subtract 42 from 48 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.

Going ahead to step 7:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 130936.8
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.

Advancing to step 8:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 130936.85
If we subtract 35 from 40, we 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 9:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 130936.857
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.

Step 10:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 130936.8571
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.

Moving on to step 11:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 130936.85714
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 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 130936.857142
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.

Let's proceed to step 13:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 130936.8571428
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.

Advancing to step 14:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 130936.85714285
If we take 35 away from 40, we end up 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.

The quotient of the division is 130936.85714285, and the remainder is 5e-09.
