627393 divided by 7 
The aim is to understand the frequency of 7 in 627393.

Let's proceed to step 1:
7 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 7

On to step 2:
When dividing 62 by 7, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 56 from 62, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 7

Let's proceed to step 3:
7 goes into 67 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we take 63 away from 67, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Step 4:
The number 7 fits into 43 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 896.0
If we subtract 42 from 43, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 7

Moving on to step 5:
If we divide 19 by 7, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 8962.0
Subtracting 14 from 19 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 7

Going ahead to step 6:
When dividing 53 by 7, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 89627.0
Subtract 49 from 53 to 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 7:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 89627.5
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.

Going ahead to step 8:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 89627.57
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.

On to step 9:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 89627.571
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.

Going ahead to step 10:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 89627.5714
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.

Going ahead to step 11:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 89627.57142
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.

Advancing to step 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 89627.571428
Subtract 56 from 60 to 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 13:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 89627.5714285
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.

Going ahead to step 14:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 89627.57142857
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.

After the division, we end up with 89627.57142857 and a remainder of 1e-09.
