Let's divide 81061926 by 259
The aim is to understand the frequency of 259 in 81061926.

On to step 1:
259 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 259

On to step 2:
259 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 259

Moving on to step 3:
810 divided by 259 is 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 777 away from 810, we end up with 33.
Take the next digit (6) from the dividend and append it to 33, then repeat: 336 / 259

Advancing to step 4:
The number 259 fits into 336 1 times, leaving a remainder of 77.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 259 from 336 and we're left with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 259

Advancing to step 5:
771 divided by 259 is 2 with a remainder of 253.
Use 2 as the next digit of our solution. 
Result so far: 312.0
If we subtract 518 from 771, we get 253.
Take the next digit (9) from the dividend and append it to 253, then repeat: 2539 / 259

Advancing to step 6:
259 goes into 2539 9 times with a remainder of 208.
Record the quotient 9 as the next digit in the result. 
Result so far: 3129.0
Deduct 2331 from 2539 and we're left with 208.
Include the next digit (2) from the dividend after 208, then repeat: 2082 / 259

On to step 7:
259 can be fit into 2082 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 31298.0
If we take 2072 away from 2082, we end up with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 259

Step 8:
259 goes into 106 0 times with a remainder of 106.
The number 0 becomes the next digit in our result. 
Result so far: 312980.0
If we take 0 away from 106, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
When dividing 1060 by 259, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 312980.4
Subtracting 1036 from 1060 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 10:
240 divided by 259 is 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 312980.4
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 11:
If we divide 2400 by 259, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 312980.409
Subtract 2331 from 2400 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
If we divide 690 by 259, we get 2 and a remainder of 172.
The next digit of our result is 2. 
Result so far: 312980.4092
The remainder is 172 after subtracting 518 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 13:
The number 259 fits into 1720 6 times, leaving a remainder of 166.
The next digit of our result is 6. 
Result so far: 312980.40926
If we take 1554 away from 1720, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 14:
259 goes into 1660 6 times with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 312980.409266
If we take 1554 away from 1660, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 312980.409266 with a remaining 1.06e-05.
