We divide 73966 by 7
The aim is to understand the frequency of 7 in 73966.

Let's proceed to step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 7 from 7 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 7

Moving on to step 2:
7 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 7

Going ahead to step 3:
7 goes into 39 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtract 35 from 39 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 7

Step 4:
The number 7 fits into 46 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1056.0
If we subtract 42 from 46, we get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 7

Advancing to step 5:
When dividing 46 by 7, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 10566.0
If we subtract 42 from 46, 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 6:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 10566.5
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.

Step 7:
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: 10566.57
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 8:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 10566.571
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.

Let's proceed to step 9:
When dividing 30 by 7, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 10566.5714
Deduct 28 from 30 and we're left 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.

Moving on to step 10:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 10566.57142
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 11:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10566.571428
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.

Step 12:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10566.5714285
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.

Moving on to step 13:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 10566.57142857
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.

Our division results in 10566.57142857 with a remaining 1e-09.
