We look at the division of 72155698 by 259 
The aim is to understand the frequency of 259 in 72155698.

On to step 1:
When dividing 7 by 259, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 259

Step 2:
259 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 259

On to step 3:
721 divided by 259 is 2 with a remainder of 203.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 518 from 721 to get 203.
Include the next digit (5) from the dividend after 203, then repeat: 2035 / 259

Step 4:
259 goes into 2035 7 times with a remainder of 222.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
The remainder is 222 after subtracting 1813 from 2035.
Fetch the next digit (5) from the dividend, attach it to 222 and continue: 2225 / 259

Going ahead to step 5:
259 can be fit into 2225 8 times, resulting in a remainder of 153.
Use 8 as the next digit of our solution. 
Result so far: 278.0
Deduct 2072 from 2225 and we're left with 153.
Take the next digit (6) from the dividend and append it to 153, then repeat: 1536 / 259

Going ahead to step 6:
If we divide 1536 by 259, we get 5 and a remainder of 241.
Put 5 as the next digit of the answer. 
Result so far: 2785.0
If we subtract 1295 from 1536, we get 241.
Bring next digit (9) of the dividend behind the 241 and repeat the process: 2419 / 259

Moving on to step 7:
259 goes into 2419 9 times with a remainder of 88.
Write down 9 as next digit of the result. 
Result so far: 27859.0
The remainder is 88 after subtracting 2331 from 2419.
Include the next digit (8) from the dividend after 88, then repeat: 888 / 259

Moving on to step 8:
The number 259 fits into 888 3 times, leaving a remainder of 111.
Record the quotient 3 as the next digit in the result. 
Result so far: 278593.0
Subtract 777 from 888 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 9:
1110 divided by 259 is 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 278593.4
Deduct 1036 from 1110 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 10:
259 can be fit into 740 2 times, resulting in a remainder of 222.
Write down 2 as next digit of the result. 
Result so far: 278593.42
Subtracting 518 from 740 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Step 11:
When dividing 2220 by 259, we get 8 with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 278593.428
If we subtract 2072 from 2220, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 12:
If we divide 1480 by 259, we get 5 and a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 278593.4285
Subtracting 1295 from 1480 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 13:
259 can be fit into 1850 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 278593.42857
Deduct 1813 from 1850 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
If we divide 370 by 259, we get 1 and a remainder of 111.
Write down 1 as next digit of the result. 
Result so far: 278593.428571
Deduct 259 from 370 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 15:
If we divide 1110 by 259, we get 4 and a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 278593.4285714
If we take 1036 away from 1110, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 16:
259 goes into 740 2 times with a remainder of 222.
Use 2 as the next digit of our solution. 
Result so far: 278593.42857142
The remainder is 222 after subtracting 518 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

In conclusion, the division gives 278593.42857142 with a balance of 2.22e-07.
