We look at the division of 10083248 by 434 
The aim is to understand the frequency of 434 in 10083248.

On to step 1:
When dividing 1 by 434, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 434

Let's proceed to step 2:
10 divided by 434 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 434

On to step 3:
100 divided by 434 is 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 100, we end up with 100.
Grab the next digit (8) from the dividend, add it to 100, then carry on: 1008 / 434

On to step 4:
434 can be fit into 1008 2 times, resulting in a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 140 after subtracting 868 from 1008.
Take the next digit (3) from the dividend and append it to 140, then repeat: 1403 / 434

On to step 5:
1403 divided by 434 is 3 with a remainder of 101.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 1302 from 1403 and we're left with 101.
Fetch the next digit (2) from the dividend, attach it to 101 and continue: 1012 / 434

Step 6:
434 goes into 1012 2 times with a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 232.0
Subtract 868 from 1012 to get 144.
Append the next digit (4) from the dividend to 144 and continue with: 1444 / 434

On to step 7:
434 goes into 1444 3 times with a remainder of 142.
The next digit of our result is 3. 
Result so far: 2323.0
Subtract 1302 from 1444 to get 142.
Grab the next digit (8) from the dividend, add it to 142, then carry on: 1428 / 434

Let's proceed to step 8:
If we divide 1428 by 434, we get 3 and a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 23233.0
Subtract 1302 from 1428 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
When dividing 1260 by 434, we get 2 with a remainder of 392.
Record the quotient 2 as the next digit in the result. 
Result so far: 23233.2
Subtract 868 from 1260 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
The number 434 fits into 3920 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 23233.29
The remainder is 14 after subtracting 3906 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
If we divide 140 by 434, we get 0 and a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 23233.29
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 12:
1400 divided by 434 is 3 with a remainder of 98.
The next digit of our result is 3. 
Result so far: 23233.2903
If we take 1302 away from 1400, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 13:
The number 434 fits into 980 2 times, leaving a remainder of 112.
Put 2 as the next digit of the answer. 
Result so far: 23233.29032
Subtracting 868 from 980 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 14:
When dividing 1120 by 434, we get 2 with a remainder of 252.
Write down 2 as next digit of the result. 
Result so far: 23233.290322
If we take 868 away from 1120, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

After the division, we end up with 23233.290322 and a remainder of 2.52e-05.
