4079515 ÷ 434 
The aim is to understand the frequency of 434 in 4079515.

Advancing to step 1:
The number 434 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 434

Moving on to step 2:
434 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 434

Moving on to step 3:
If we divide 407 by 434, we get 0 and a remainder of 407.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 407, we end up with 407.
Include the next digit (9) from the dividend after 407, then repeat: 4079 / 434

On to step 4:
If we divide 4079 by 434, we get 9 and a remainder of 173.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 3906 away from 4079, we end up with 173.
Include the next digit (5) from the dividend after 173, then repeat: 1735 / 434

Let's proceed to step 5:
1735 divided by 434 is 3 with a remainder of 433.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 1302 away from 1735, we end up with 433.
Bring next digit (1) of the dividend behind the 433 and repeat the process: 4331 / 434

Going ahead to step 6:
If we divide 4331 by 434, we get 9 and a remainder of 425.
Put 9 as the next digit of the answer. 
Result so far: 939.0
The remainder is 425 after subtracting 3906 from 4331.
Fetch the next digit (5) from the dividend, attach it to 425 and continue: 4255 / 434

Moving on to step 7:
434 can be fit into 4255 9 times, resulting in a remainder of 349.
Write down 9 as next digit of the result. 
Result so far: 9399.0
Subtract 3906 from 4255 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Step 8:
434 goes into 3490 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 9399.8
The remainder is 18 after subtracting 3472 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 9:
When dividing 180 by 434, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 9399.8
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
434 can be fit into 1800 4 times, resulting in a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 9399.804
If we subtract 1736 from 1800, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
If we divide 640 by 434, we get 1 and a remainder of 206.
Write down 1 as next digit of the result. 
Result so far: 9399.8041
Subtracting 434 from 640 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 12:
2060 divided by 434 is 4 with a remainder of 324.
Record the quotient 4 as the next digit in the result. 
Result so far: 9399.80414
If we subtract 1736 from 2060, we get 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Let's proceed to step 13:
When dividing 3240 by 434, we get 7 with a remainder of 202.
Write down 7 as next digit of the result. 
Result so far: 9399.804147
Deduct 3038 from 3240 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 14:
2020 divided by 434 is 4 with a remainder of 284.
Record the quotient 4 as the next digit in the result. 
Result so far: 9399.8041474
If we take 1736 away from 2020, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 15:
The number 434 fits into 2840 6 times, leaving a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 9399.80414746
If we take 2604 away from 2840, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

The final outcome is 9399.80414746, with a leftover of 2.36e-07.
