We're dividing 433831 by 7 
The aim is to understand the frequency of 7 in 433831.

Going ahead to step 1:
If we divide 4 by 7, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 7

Let's proceed to step 2:
The number 7 fits into 43 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 42 from 43 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 7

On to step 3:
7 can be fit into 13 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Deduct 7 from 13 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 7

Step 4:
7 goes into 68 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 619.0
If we take 63 away from 68, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 7

Let's proceed to step 5:
If we divide 53 by 7, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 6197.0
Subtracting 49 from 53 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 7

Advancing to step 6:
41 divided by 7 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 61975.0
If we take 35 away from 41, 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.

Moving on to step 7:
If we divide 60 by 7, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 61975.8
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:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 61975.85
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.

On to step 9:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 61975.857
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.

Advancing to step 10:
7 goes into 10 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 61975.8571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
If we divide 30 by 7, we get 4 and a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 61975.85714
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.

Advancing to step 12:
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: 61975.857142
If we subtract 14 from 20, we 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.

Moving on to step 13:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 61975.8571428
The remainder is 4 after subtracting 56 from 60.
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 14:
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: 61975.85714285
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.

The quotient of the division is 61975.85714285, and the remainder is 5e-09.
