We're dividing 8348603 by 434 
The aim is to understand the frequency of 434 in 8348603.

Let's proceed to step 1:
If we divide 8 by 434, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 434

Step 2:
434 can be fit into 83 0 times, resulting in a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Bring next digit (4) of the dividend behind the 83 and repeat the process: 834 / 434

Moving on to step 3:
434 can be fit into 834 1 times, resulting in a remainder of 400.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 434 away from 834, we end up with 400.
Grab the next digit (8) from the dividend, add it to 400, then carry on: 4008 / 434

Advancing to step 4:
434 goes into 4008 9 times with a remainder of 102.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 102 after subtracting 3906 from 4008.
Take the next digit (6) from the dividend and append it to 102, then repeat: 1026 / 434

Let's proceed to step 5:
434 goes into 1026 2 times with a remainder of 158.
The next digit of our result is 2. 
Result so far: 192.0
If we subtract 868 from 1026, we get 158.
Bring next digit (0) of the dividend behind the 158 and repeat the process: 1580 / 434

Step 6:
1580 divided by 434 is 3 with a remainder of 278.
Record the quotient 3 as the next digit in the result. 
Result so far: 1923.0
Deduct 1302 from 1580 and we're left with 278.
Append the next digit (3) from the dividend to 278 and continue with: 2783 / 434

Advancing to step 7:
If we divide 2783 by 434, we get 6 and a remainder of 179.
Put 6 as the next digit of the answer. 
Result so far: 19236.0
The remainder is 179 after subtracting 2604 from 2783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 8:
If we divide 1790 by 434, we get 4 and a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 19236.4
Subtracting 1736 from 1790 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 9:
540 divided by 434 is 1 with a remainder of 106.
Use 1 as the next digit of our solution. 
Result so far: 19236.41
Deduct 434 from 540 and we're left with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 10:
1060 divided by 434 is 2 with a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 19236.412
If we take 868 away from 1060, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 11:
When dividing 1920 by 434, we get 4 with a remainder of 184.
Write down 4 as next digit of the result. 
Result so far: 19236.4124
If we subtract 1736 from 1920, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 12:
The number 434 fits into 1840 4 times, leaving a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 19236.41244
If we take 1736 away from 1840, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 19236.41244 and a remainder of 0.000104.
