25531955 ÷ 453 
The aim is to understand the frequency of 453 in 25531955.

Step 1:
453 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 453

Moving on to step 2:
If we divide 25 by 453, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 453

Step 3:
453 goes into 255 0 times with a remainder of 255.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 255 after subtracting 0 from 255.
Include the next digit (3) from the dividend after 255, then repeat: 2553 / 453

Step 4:
If we divide 2553 by 453, we get 5 and a remainder of 288.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 2265 from 2553 to get 288.
Append the next digit (1) from the dividend to 288 and continue with: 2881 / 453

On to step 5:
453 goes into 2881 6 times with a remainder of 163.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Deduct 2718 from 2881 and we're left with 163.
Append the next digit (9) from the dividend to 163 and continue with: 1639 / 453

Step 6:
The number 453 fits into 1639 3 times, leaving a remainder of 280.
Record the quotient 3 as the next digit in the result. 
Result so far: 563.0
If we subtract 1359 from 1639, we get 280.
Grab the next digit (5) from the dividend, add it to 280, then carry on: 2805 / 453

Step 7:
453 goes into 2805 6 times with a remainder of 87.
Use 6 as the next digit of our solution. 
Result so far: 5636.0
If we subtract 2718 from 2805, we get 87.
Take the next digit (5) from the dividend and append it to 87, then repeat: 875 / 453

Moving on to step 8:
453 can be fit into 875 1 times, resulting in a remainder of 422.
Use 1 as the next digit of our solution. 
Result so far: 56361.0
The remainder is 422 after subtracting 453 from 875.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 9:
When dividing 4220 by 453, we get 9 with a remainder of 143.
Write down 9 as next digit of the result. 
Result so far: 56361.9
Subtracting 4077 from 4220 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Going ahead to step 10:
If we divide 1430 by 453, we get 3 and a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 56361.93
Deduct 1359 from 1430 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 11:
453 can be fit into 710 1 times, resulting in a remainder of 257.
Write down 1 as next digit of the result. 
Result so far: 56361.931
If we subtract 453 from 710, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Step 12:
2570 divided by 453 is 5 with a remainder of 305.
Record the quotient 5 as the next digit in the result. 
Result so far: 56361.9315
Deduct 2265 from 2570 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 13:
453 can be fit into 3050 6 times, resulting in a remainder of 332.
Write down 6 as next digit of the result. 
Result so far: 56361.93156
Subtracting 2718 from 3050 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 14:
When dividing 3320 by 453, we get 7 with a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 56361.931567
The remainder is 149 after subtracting 3171 from 3320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 15:
When dividing 1490 by 453, we get 3 with a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 56361.9315673
If we subtract 1359 from 1490, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 16:
1310 divided by 453 is 2 with a remainder of 404.
Use 2 as the next digit of our solution. 
Result so far: 56361.93156732
If we subtract 906 from 1310, we get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

After the division, we end up with 56361.93156732 and a remainder of 4.04e-07.
