We divide 453547 by 7
The aim is to understand the frequency of 7 in 453547.

Step 1:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 7

Advancing to step 2:
When dividing 45 by 7, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 42 from 45 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 7

Moving on to step 3:
7 can be fit into 33 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 28 from 33 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 7

Step 4:
7 can be fit into 55 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 647.0
If we take 49 away from 55, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 7

Let's proceed to step 5:
64 divided by 7 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 6479.0
Subtracting 63 from 64 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 7

Let's proceed to step 6:
When dividing 17 by 7, we get 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 64792.0
Deduct 14 from 17 and we're left 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.

Advancing to step 7:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 64792.4
The remainder is 2 after subtracting 28 from 30.
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 8:
20 divided by 7 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 64792.42
Subtracting 14 from 20 leaves us 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 9:
7 goes into 60 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 64792.428
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.

Moving on to step 10:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 64792.4285
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.

Moving on to step 11:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 64792.42857
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.

Step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 64792.428571
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.

Let's proceed to step 13:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 64792.4285714
If we subtract 28 from 30, we get 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:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 64792.42857142
Subtracting 14 from 20 leaves us 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.

In conclusion, the division gives 64792.42857142 with a balance of 6e-09.
