Let's divide 38544021 by 452
The aim is to understand the frequency of 452 in 38544021.

Going ahead to step 1:
When dividing 3 by 452, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 452

Step 2:
The number 452 fits into 38 0 times, leaving a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 452

Advancing to step 3:
If we divide 385 by 452, we get 0 and a remainder of 385.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 385 to get 385.
Bring next digit (4) of the dividend behind the 385 and repeat the process: 3854 / 452

Moving on to step 4:
3854 divided by 452 is 8 with a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 3616 from 3854 to get 238.
Bring next digit (4) of the dividend behind the 238 and repeat the process: 2384 / 452

On to step 5:
452 can be fit into 2384 5 times, resulting in a remainder of 124.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 2260 from 2384, we get 124.
Fetch the next digit (0) from the dividend, attach it to 124 and continue: 1240 / 452

Moving on to step 6:
1240 divided by 452 is 2 with a remainder of 336.
The number 2 becomes the next digit in our result. 
Result so far: 852.0
Subtract 904 from 1240 to get 336.
Fetch the next digit (2) from the dividend, attach it to 336 and continue: 3362 / 452

Moving on to step 7:
The number 452 fits into 3362 7 times, leaving a remainder of 198.
The next digit of our result is 7. 
Result so far: 8527.0
Subtract 3164 from 3362 to get 198.
Include the next digit (1) from the dividend after 198, then repeat: 1981 / 452

Going ahead to step 8:
452 can be fit into 1981 4 times, resulting in a remainder of 173.
Record the quotient 4 as the next digit in the result. 
Result so far: 85274.0
If we subtract 1808 from 1981, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 9:
If we divide 1730 by 452, we get 3 and a remainder of 374.
The next digit of our result is 3. 
Result so far: 85274.3
If we subtract 1356 from 1730, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Advancing to step 10:
If we divide 3740 by 452, we get 8 and a remainder of 124.
The next digit of our result is 8. 
Result so far: 85274.38
Subtracting 3616 from 3740 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
1240 divided by 452 is 2 with a remainder of 336.
Write down 2 as next digit of the result. 
Result so far: 85274.382
Deduct 904 from 1240 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 12:
If we divide 3360 by 452, we get 7 and a remainder of 196.
Record the quotient 7 as the next digit in the result. 
Result so far: 85274.3827
The remainder is 196 after subtracting 3164 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 13:
The number 452 fits into 1960 4 times, leaving a remainder of 152.
Use 4 as the next digit of our solution. 
Result so far: 85274.38274
If we subtract 1808 from 1960, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 14:
If we divide 1520 by 452, we get 3 and a remainder of 164.
Put 3 as the next digit of the answer. 
Result so far: 85274.382743
Deduct 1356 from 1520 and we're left with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 15:
452 can be fit into 1640 3 times, resulting in a remainder of 284.
The number 3 becomes the next digit in our result. 
Result so far: 85274.3827433
If we take 1356 away from 1640, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

In conclusion, the division gives 85274.3827433 with a balance of 2.84e-06.
