We're dividing 10343542 by 453 
The aim is to understand the frequency of 453 in 10343542.

Going ahead to step 1:
The number 453 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 453

Let's proceed to step 2:
The number 453 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 453

Moving on to step 3:
453 can be fit into 103 0 times, resulting in a remainder of 103.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 103 leaves us with 103.
Take the next digit (4) from the dividend and append it to 103, then repeat: 1034 / 453

On to step 4:
453 can be fit into 1034 2 times, resulting in a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 906 from 1034 and we're left with 128.
Grab the next digit (3) from the dividend, add it to 128, then carry on: 1283 / 453

On to step 5:
453 goes into 1283 2 times with a remainder of 377.
The next digit of our result is 2. 
Result so far: 22.0
If we take 906 away from 1283, we end up with 377.
Grab the next digit (5) from the dividend, add it to 377, then carry on: 3775 / 453

Moving on to step 6:
453 can be fit into 3775 8 times, resulting in a remainder of 151.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Deduct 3624 from 3775 and we're left with 151.
Grab the next digit (4) from the dividend, add it to 151, then carry on: 1514 / 453

On to step 7:
1514 divided by 453 is 3 with a remainder of 155.
Use 3 as the next digit of our solution. 
Result so far: 2283.0
Subtract 1359 from 1514 to get 155.
Include the next digit (2) from the dividend after 155, then repeat: 1552 / 453

Let's proceed to step 8:
453 goes into 1552 3 times with a remainder of 193.
The next digit of our result is 3. 
Result so far: 22833.0
Subtract 1359 from 1552 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 9:
453 can be fit into 1930 4 times, resulting in a remainder of 118.
Put 4 as the next digit of the answer. 
Result so far: 22833.4
Subtracting 1812 from 1930 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 10:
453 can be fit into 1180 2 times, resulting in a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 22833.42
If we take 906 away from 1180, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 11:
453 can be fit into 2740 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 22833.426
Deduct 2718 from 2740 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
If we divide 220 by 453, we get 0 and a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 22833.426
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 13:
The number 453 fits into 2200 4 times, leaving a remainder of 388.
Use 4 as the next digit of our solution. 
Result so far: 22833.42604
Subtract 1812 from 2200 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 14:
453 can be fit into 3880 8 times, resulting in a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 22833.426048
Deduct 3624 from 3880 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 15:
The number 453 fits into 2560 5 times, leaving a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 22833.4260485
Subtract 2265 from 2560 to get 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Advancing to step 16:
453 can be fit into 2950 6 times, resulting in a remainder of 232.
The next digit of our result is 6. 
Result so far: 22833.42604856
Deduct 2718 from 2950 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

After the division, we end up with 22833.42604856 and a remainder of 2.32e-07.
