12117918 divided by 259 
The aim is to understand the frequency of 259 in 12117918.

Step 1:
1 divided by 259 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 259

Moving on to step 2:
12 divided by 259 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 259

Advancing to step 3:
259 goes into 121 0 times with a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 121, we get 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 259

Going ahead to step 4:
When dividing 1211 by 259, we get 4 with a remainder of 175.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 1036 from 1211 to get 175.
Take the next digit (7) from the dividend and append it to 175, then repeat: 1757 / 259

On to step 5:
The number 259 fits into 1757 6 times, leaving a remainder of 203.
Use 6 as the next digit of our solution. 
Result so far: 46.0
If we take 1554 away from 1757, we end up with 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 259

Going ahead to step 6:
259 can be fit into 2039 7 times, resulting in a remainder of 226.
Write down 7 as next digit of the result. 
Result so far: 467.0
Subtract 1813 from 2039 to get 226.
Fetch the next digit (1) from the dividend, attach it to 226 and continue: 2261 / 259

Let's proceed to step 7:
259 goes into 2261 8 times with a remainder of 189.
Record the quotient 8 as the next digit in the result. 
Result so far: 4678.0
If we subtract 2072 from 2261, we get 189.
Append the next digit (8) from the dividend to 189 and continue with: 1898 / 259

Step 8:
The number 259 fits into 1898 7 times, leaving a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 46787.0
The remainder is 85 after subtracting 1813 from 1898.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 9:
850 divided by 259 is 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 46787.3
If we take 777 away from 850, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 10:
The number 259 fits into 730 2 times, leaving a remainder of 212.
The number 2 becomes the next digit in our result. 
Result so far: 46787.32
The remainder is 212 after subtracting 518 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 11:
259 can be fit into 2120 8 times, resulting in a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 46787.328
Subtracting 2072 from 2120 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
When dividing 480 by 259, we get 1 with a remainder of 221.
The number 1 becomes the next digit in our result. 
Result so far: 46787.3281
Subtracting 259 from 480 leaves us with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 13:
When dividing 2210 by 259, we get 8 with a remainder of 138.
Put 8 as the next digit of the answer. 
Result so far: 46787.32818
Subtract 2072 from 2210 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 14:
The number 259 fits into 1380 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 46787.328185
Subtract 1295 from 1380 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 15:
The number 259 fits into 850 3 times, leaving a remainder of 73.
Put 3 as the next digit of the answer. 
Result so far: 46787.3281853
Subtracting 777 from 850 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 16:
If we divide 730 by 259, we get 2 and a remainder of 212.
The next digit of our result is 2. 
Result so far: 46787.32818532
Deduct 518 from 730 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

In conclusion, the division gives 46787.32818532 with a balance of 2.12e-07.
