We're dividing 25800530 by 344 
The aim is to understand the frequency of 344 in 25800530.

Advancing to step 1:
2 divided by 344 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 344

On to step 2:
If we divide 25 by 344, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 344

Moving on to step 3:
344 can be fit into 258 0 times, resulting in a remainder of 258.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 258, we get 258.
Append the next digit (0) from the dividend to 258 and continue with: 2580 / 344

Step 4:
The number 344 fits into 2580 7 times, leaving a remainder of 172.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 2408 from 2580, we get 172.
Append the next digit (0) from the dividend to 172 and continue with: 1720 / 344

Step 5:
If we divide 1720 by 344, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 1720 from 1720 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 344

Moving on to step 6:
If we divide 5 by 344, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 750.0
If we subtract 0 from 5, we get 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 344

Going ahead to step 7:
If we divide 53 by 344, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 7500.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 344

Advancing to step 8:
344 can be fit into 530 1 times, resulting in a remainder of 186.
Put 1 as the next digit of the answer. 
Result so far: 75001.0
If we subtract 344 from 530, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 9:
The number 344 fits into 1860 5 times, leaving a remainder of 140.
Record the quotient 5 as the next digit in the result. 
Result so far: 75001.5
If we subtract 1720 from 1860, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
When dividing 1400 by 344, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 75001.54
Subtracting 1376 from 1400 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
344 can be fit into 240 0 times, resulting in a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 75001.54
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 12:
If we divide 2400 by 344, we get 6 and a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 75001.5406
If we take 2064 away from 2400, we end up 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.

Moving on to step 13:
344 goes into 3360 9 times with a remainder of 264.
Use 9 as the next digit of our solution. 
Result so far: 75001.54069
The remainder is 264 after subtracting 3096 from 3360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 14:
344 goes into 2640 7 times with a remainder of 232.
Put 7 as the next digit of the answer. 
Result so far: 75001.540697
Subtract 2408 from 2640 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 15:
The number 344 fits into 2320 6 times, leaving a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 75001.5406976
Deduct 2064 from 2320 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.

Step 16:
344 goes into 2560 7 times with a remainder of 152.
Use 7 as the next digit of our solution. 
Result so far: 75001.54069767
If we subtract 2408 from 2560, 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.

The final outcome is 75001.54069767, with a leftover of 1.52e-07.
