We're dividing 434434 by 7 
The aim is to understand the frequency of 7 in 434434.

On to step 1:
7 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Going ahead to step 2:
43 divided by 7 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 42 away from 43, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 7

On to step 3:
7 goes into 14 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 14 from 14 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 7

Let's proceed to step 4:
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: 620.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 7

Advancing to step 5:
43 divided by 7 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6206.0
Deduct 42 from 43 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 7

Step 6:
If we divide 14 by 7, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 62062.0
Subtract 14 from 14 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 62062.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 7 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 62062.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 62062.0 with a remainder of 0.0.
