963862 divided by 7 
The aim is to understand the frequency of 7 in 963862.

Step 1:
The number 7 fits into 9 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 7 from 9 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 7

Advancing to step 2:
When dividing 26 by 7, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 21 from 26, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 7

Step 3:
7 can be fit into 53 7 times, resulting in a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtracting 49 from 53 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 7

Moving on to step 4:
When dividing 48 by 7, we get 6 with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 1376.0
Deduct 42 from 48 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 7

Going ahead to step 5:
66 divided by 7 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 13769.0
Deduct 63 from 66 and we're left with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 7

Step 6:
7 goes into 32 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 137694.0
If we take 28 away from 32, 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.

Let's proceed 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: 137694.5
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.

Step 8:
If we divide 50 by 7, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 137694.57
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.

Let's proceed to step 9:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 137694.571
Subtracting 7 from 10 leaves us 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:
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: 137694.5714
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.

Step 11:
If we divide 20 by 7, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 137694.57142
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:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 137694.571428
Deduct 56 from 60 and we're left 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 13:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 137694.5714285
The remainder is 5 after subtracting 35 from 40.
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:
If we divide 50 by 7, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 137694.57142857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

In conclusion, the division gives 137694.57142857 with a balance of 1e-09.
