Let's divide 8473490 by 259
The aim is to understand the frequency of 259 in 8473490.

On to step 1:
If we divide 8 by 259, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 259

Advancing to step 2:
If we divide 84 by 259, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 259

Going ahead to step 3:
259 can be fit into 847 3 times, resulting in a remainder of 70.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 70 after subtracting 777 from 847.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 259

Moving on to step 4:
The number 259 fits into 703 2 times, leaving a remainder of 185.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtract 518 from 703 to get 185.
Append the next digit (4) from the dividend to 185 and continue with: 1854 / 259

Advancing to step 5:
259 goes into 1854 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 327.0
Subtracting 1813 from 1854 leaves us with 41.
Grab the next digit (9) from the dividend, add it to 41, then carry on: 419 / 259

Advancing to step 6:
When dividing 419 by 259, we get 1 with a remainder of 160.
Write down 1 as next digit of the result. 
Result so far: 3271.0
Subtract 259 from 419 to get 160.
Take the next digit (0) from the dividend and append it to 160, then repeat: 1600 / 259

Going ahead to step 7:
259 goes into 1600 6 times with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 32716.0
If we subtract 1554 from 1600, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
259 goes into 460 1 times with a remainder of 201.
Use 1 as the next digit of our solution. 
Result so far: 32716.1
Subtracting 259 from 460 leaves us with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 9:
If we divide 2010 by 259, we get 7 and a remainder of 197.
Record the quotient 7 as the next digit in the result. 
Result so far: 32716.17
Subtract 1813 from 2010 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Going ahead to step 10:
259 can be fit into 1970 7 times, resulting in a remainder of 157.
Write down 7 as next digit of the result. 
Result so far: 32716.177
The remainder is 157 after subtracting 1813 from 1970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

The final result is 32716.177 with a remainder of 0.0157.
