431189 ÷ 7 
The aim is to understand the frequency of 7 in 431189.

Let's proceed to step 1:
When dividing 4 by 7, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Step 2:
When dividing 43 by 7, we get 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 42 from 43 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 7

Step 3:
When dividing 11 by 7, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we take 7 away from 11, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 7

Let's proceed to step 4:
7 can be fit into 41 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 615.0
Subtracting 35 from 41 leaves us with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

Step 5:
If we divide 68 by 7, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 6159.0
If we subtract 63 from 68, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 7

Step 6:
When dividing 59 by 7, we get 8 with a remainder of 3.
The next digit of our result is 8. 
Result so far: 61598.0
If we take 56 away from 59, 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.

Step 7:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 61598.4
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.

Let's proceed to step 8:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 61598.42
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 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 61598.428
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.

Advancing to step 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 61598.4285
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.

Let's proceed to step 11:
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: 61598.42857
Subtracting 49 from 50 leaves us 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 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 61598.428571
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.

Advancing to step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 61598.4285714
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.

On to step 14:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 61598.42857142
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.

The final outcome is 61598.42857142, with a leftover of 6e-09.
