We're dividing 454441 by 7 
The aim is to understand the frequency of 7 in 454441.

Advancing to step 1:
4 divided by 7 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 7

Let's proceed to step 2:
7 goes into 45 6 times 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.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 7

Going ahead to step 3:
7 can be fit into 34 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 28 from 34 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 7

Going ahead to step 4:
7 can be fit into 64 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 649.0
The remainder is 1 after subtracting 63 from 64.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 7

Going ahead to step 5:
The number 7 fits into 14 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 6492.0
Deduct 14 from 14 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 7

Let's proceed to step 6:
1 divided by 7 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 64920.0
Subtract 0 from 1 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.

Moving on to step 7:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 64920.1
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 8:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 64920.14
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.

Let's proceed to step 9:
20 divided by 7 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 64920.142
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 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 64920.1428
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.

Going ahead to step 11:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 64920.14285
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.

Advancing to step 12:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 64920.142857
If we subtract 49 from 50, we 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.

Advancing to step 13:
If we divide 10 by 7, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 64920.1428571
Deduct 7 from 10 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.

Going ahead to step 14:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 64920.14285714
Subtracting 28 from 30 leaves us 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.

The final outcome is 64920.14285714, with a leftover of 2e-09.
