Let's divide 39456864 by 259
The aim is to understand the frequency of 259 in 39456864.

Moving on to step 1:
When dividing 3 by 259, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 259

Advancing to step 2:
If we divide 39 by 259, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (4) from the dividend, add it to 39, then carry on: 394 / 259

On to step 3:
259 can be fit into 394 1 times, resulting in a remainder of 135.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 259 from 394, we get 135.
Include the next digit (5) from the dividend after 135, then repeat: 1355 / 259

Moving on to step 4:
1355 divided by 259 is 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 1295 from 1355 leaves us with 60.
Include the next digit (6) from the dividend after 60, then repeat: 606 / 259

Going ahead to step 5:
When dividing 606 by 259, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we take 518 away from 606, we end up with 88.
Grab the next digit (8) from the dividend, add it to 88, then carry on: 888 / 259

Let's proceed to step 6:
888 divided by 259 is 3 with a remainder of 111.
Put 3 as the next digit of the answer. 
Result so far: 1523.0
If we take 777 away from 888, we end up with 111.
Bring next digit (6) of the dividend behind the 111 and repeat the process: 1116 / 259

Going ahead to step 7:
When dividing 1116 by 259, we get 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 15234.0
Subtracting 1036 from 1116 leaves us with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 259

Step 8:
The number 259 fits into 804 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 152343.0
Deduct 777 from 804 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 9:
270 divided by 259 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 152343.1
The remainder is 11 after subtracting 259 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
259 can be fit into 110 0 times, resulting in a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 152343.1
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 11:
If we divide 1100 by 259, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 152343.104
Subtracting 1036 from 1100 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
When dividing 640 by 259, we get 2 with a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 152343.1042
If we take 518 away from 640, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Moving on to step 13:
1220 divided by 259 is 4 with a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 152343.10424
Subtract 1036 from 1220 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 14:
259 goes into 1840 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 152343.104247
Subtract 1813 from 1840 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 15:
270 divided by 259 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 152343.1042471
If we take 259 away from 270, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 16:
110 divided by 259 is 0 with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 152343.1042471
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

After the division, we end up with 152343.1042471 and a remainder of 1.1e-07.
