We divide 554663 by 7
The aim is to understand the frequency of 7 in 554663.

On to step 1:
7 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 7

On to step 2:
7 can be fit into 55 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 49 from 55, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 7

Going ahead to step 3:
64 divided by 7 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Subtracting 63 from 64 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 7

Moving on to step 4:
When dividing 16 by 7, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 792.0
The remainder is 2 after subtracting 14 from 16.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 7

On to step 5:
When dividing 26 by 7, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 7923.0
If we take 21 away from 26, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 7

Moving on to step 6:
The number 7 fits into 53 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 79237.0
Subtracting 49 from 53 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.

Step 7:
40 divided by 7 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 79237.5
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 8:
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: 79237.57
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.

Moving on to step 9:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 79237.571
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.

Moving on to step 10:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 79237.5714
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.

On to step 11:
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: 79237.57142
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.

Advancing to step 12:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 79237.571428
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.

Step 13:
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: 79237.5714285
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.

On to step 14:
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: 79237.57142857
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.

The final outcome is 79237.57142857, with a leftover of 1e-09.
