We divide 25218569 by 817
The aim is to understand the frequency of 817 in 25218569.

Moving on to step 1:
When dividing 2 by 817, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 817

Going ahead to step 2:
817 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 817

Moving on to step 3:
252 divided by 817 is 0 with a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 252 after subtracting 0 from 252.
Bring next digit (1) of the dividend behind the 252 and repeat the process: 2521 / 817

Let's proceed to step 4:
The number 817 fits into 2521 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 2451 from 2521 to get 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 817

Going ahead to step 5:
817 can be fit into 708 0 times, resulting in a remainder of 708.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 708, we end up with 708.
Grab the next digit (5) from the dividend, add it to 708, then carry on: 7085 / 817

Let's proceed to step 6:
817 goes into 7085 8 times with a remainder of 549.
Write down 8 as next digit of the result. 
Result so far: 308.0
Deduct 6536 from 7085 and we're left with 549.
Take the next digit (6) from the dividend and append it to 549, then repeat: 5496 / 817

Let's proceed to step 7:
817 goes into 5496 6 times with a remainder of 594.
Use 6 as the next digit of our solution. 
Result so far: 3086.0
If we subtract 4902 from 5496, we get 594.
Take the next digit (9) from the dividend and append it to 594, then repeat: 5949 / 817

Let's proceed to step 8:
5949 divided by 817 is 7 with a remainder of 230.
Record the quotient 7 as the next digit in the result. 
Result so far: 30867.0
Subtract 5719 from 5949 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
817 can be fit into 2300 2 times, resulting in a remainder of 666.
Record the quotient 2 as the next digit in the result. 
Result so far: 30867.2
Subtracting 1634 from 2300 leaves us with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Going ahead to step 10:
817 goes into 6660 8 times with a remainder of 124.
The number 8 becomes the next digit in our result. 
Result so far: 30867.28
Deduct 6536 from 6660 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 11:
817 can be fit into 1240 1 times, resulting in a remainder of 423.
Use 1 as the next digit of our solution. 
Result so far: 30867.281
Subtract 817 from 1240 to get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 12:
The number 817 fits into 4230 5 times, leaving a remainder of 145.
The number 5 becomes the next digit in our result. 
Result so far: 30867.2815
Subtract 4085 from 4230 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Moving on to step 13:
The number 817 fits into 1450 1 times, leaving a remainder of 633.
Use 1 as the next digit of our solution. 
Result so far: 30867.28151
Deduct 817 from 1450 and we're left with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Let's proceed to step 14:
If we divide 6330 by 817, we get 7 and a remainder of 611.
The next digit of our result is 7. 
Result so far: 30867.281517
If we take 5719 away from 6330, we end up with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Let's proceed to step 15:
The number 817 fits into 6110 7 times, leaving a remainder of 391.
Write down 7 as next digit of the result. 
Result so far: 30867.2815177
Deduct 5719 from 6110 and we're left with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

The quotient of the division is 30867.2815177, and the remainder is 3.91e-06.
