We're dividing 77681925 by 259 
The aim is to understand the frequency of 259 in 77681925.

On to step 1:
If we divide 7 by 259, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 259

Moving on to step 2:
If we divide 77 by 259, we get 0 and a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Append the next digit (6) from the dividend to 77 and continue with: 776 / 259

Let's proceed to step 3:
259 can be fit into 776 2 times, resulting in a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 518 from 776 to get 258.
Grab the next digit (8) from the dividend, add it to 258, then carry on: 2588 / 259

Going ahead to step 4:
2588 divided by 259 is 9 with a remainder of 257.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 2331 from 2588 to get 257.
Append the next digit (1) from the dividend to 257 and continue with: 2571 / 259

Going ahead to step 5:
2571 divided by 259 is 9 with a remainder of 240.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
Deduct 2331 from 2571 and we're left with 240.
Include the next digit (9) from the dividend after 240, then repeat: 2409 / 259

Advancing to step 6:
259 can be fit into 2409 9 times, resulting in a remainder of 78.
Write down 9 as next digit of the result. 
Result so far: 2999.0
If we subtract 2331 from 2409, we get 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 259

Moving on to step 7:
259 goes into 782 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 29993.0
Subtracting 777 from 782 leaves us with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 259

Advancing to step 8:
259 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 299930.0
Deduct 0 from 55 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
259 can be fit into 550 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 299930.2
Subtracting 518 from 550 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 259 is 1 with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 299930.21
Deduct 259 from 320 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
The number 259 fits into 610 2 times, leaving a remainder of 92.
The next digit of our result is 2. 
Result so far: 299930.212
The remainder is 92 after subtracting 518 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 12:
920 divided by 259 is 3 with a remainder of 143.
Put 3 as the next digit of the answer. 
Result so far: 299930.2123
Deduct 777 from 920 and we're left 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.

On to step 13:
259 goes into 1430 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 299930.21235
If we subtract 1295 from 1430, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 14:
If we divide 1350 by 259, we get 5 and a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 299930.212355
The remainder is 55 after subtracting 1295 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

After the division, we end up with 299930.212355 and a remainder of 5.5e-06.
