25399982 ÷ 452 
The aim is to understand the frequency of 452 in 25399982.

Let's proceed to step 1:
2 divided by 452 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 452

Let's proceed to step 2:
452 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 452

Going ahead to step 3:
The number 452 fits into 253 0 times, leaving a remainder of 253.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 253, we get 253.
Append the next digit (9) from the dividend to 253 and continue with: 2539 / 452

Advancing to step 4:
If we divide 2539 by 452, we get 5 and a remainder of 279.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 2260 from 2539 leaves us with 279.
Fetch the next digit (9) from the dividend, attach it to 279 and continue: 2799 / 452

Going ahead to step 5:
When dividing 2799 by 452, we get 6 with a remainder of 87.
Write down 6 as next digit of the result. 
Result so far: 56.0
Deduct 2712 from 2799 and we're left with 87.
Bring next digit (9) of the dividend behind the 87 and repeat the process: 879 / 452

Moving on to step 6:
When dividing 879 by 452, we get 1 with a remainder of 427.
Record the quotient 1 as the next digit in the result. 
Result so far: 561.0
Subtracting 452 from 879 leaves us with 427.
Grab the next digit (8) from the dividend, add it to 427, then carry on: 4278 / 452

Step 7:
When dividing 4278 by 452, we get 9 with a remainder of 210.
Use 9 as the next digit of our solution. 
Result so far: 5619.0
Subtracting 4068 from 4278 leaves us with 210.
Grab the next digit (2) from the dividend, add it to 210, then carry on: 2102 / 452

Advancing to step 8:
If we divide 2102 by 452, we get 4 and a remainder of 294.
Record the quotient 4 as the next digit in the result. 
Result so far: 56194.0
The remainder is 294 after subtracting 1808 from 2102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 9:
When dividing 2940 by 452, we get 6 with a remainder of 228.
Put 6 as the next digit of the answer. 
Result so far: 56194.6
Subtracting 2712 from 2940 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 10:
The number 452 fits into 2280 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 56194.65
If we subtract 2260 from 2280, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
452 goes into 200 0 times with a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 56194.65
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 12:
452 can be fit into 2000 4 times, resulting in a remainder of 192.
Record the quotient 4 as the next digit in the result. 
Result so far: 56194.6504
Subtract 1808 from 2000 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 13:
The number 452 fits into 1920 4 times, leaving a remainder of 112.
The next digit of our result is 4. 
Result so far: 56194.65044
Deduct 1808 from 1920 and we're left 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.

In conclusion, the division gives 56194.65044 with a balance of 0.000112.
