We look at the division of 25305236 by 878 
The aim is to understand the frequency of 878 in 25305236.

Going ahead to step 1:
If we divide 2 by 878, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 878

Let's proceed to step 2:
If we divide 25 by 878, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 878

Step 3:
878 can be fit into 253 0 times, resulting in a remainder of 253.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 253 and we're left with 253.
Take the next digit (0) from the dividend and append it to 253, then repeat: 2530 / 878

On to step 4:
If we divide 2530 by 878, we get 2 and a remainder of 774.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 1756 from 2530 to get 774.
Bring next digit (5) of the dividend behind the 774 and repeat the process: 7745 / 878

Let's proceed to step 5:
878 goes into 7745 8 times with a remainder of 721.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 7024 away from 7745, we end up with 721.
Grab the next digit (2) from the dividend, add it to 721, then carry on: 7212 / 878

Step 6:
7212 divided by 878 is 8 with a remainder of 188.
Use 8 as the next digit of our solution. 
Result so far: 288.0
Subtract 7024 from 7212 to get 188.
Fetch the next digit (3) from the dividend, attach it to 188 and continue: 1883 / 878

Step 7:
The number 878 fits into 1883 2 times, leaving a remainder of 127.
Use 2 as the next digit of our solution. 
Result so far: 2882.0
Subtracting 1756 from 1883 leaves us with 127.
Bring next digit (6) of the dividend behind the 127 and repeat the process: 1276 / 878

Going ahead to step 8:
1276 divided by 878 is 1 with a remainder of 398.
Use 1 as the next digit of our solution. 
Result so far: 28821.0
Deduct 878 from 1276 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 9:
The number 878 fits into 3980 4 times, leaving a remainder of 468.
Record the quotient 4 as the next digit in the result. 
Result so far: 28821.4
The remainder is 468 after subtracting 3512 from 3980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 10:
The number 878 fits into 4680 5 times, leaving a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 28821.45
If we take 4390 away from 4680, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 11:
If we divide 2900 by 878, we get 3 and a remainder of 266.
Use 3 as the next digit of our solution. 
Result so far: 28821.453
Subtract 2634 from 2900 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 12:
878 can be fit into 2660 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 28821.4533
The remainder is 26 after subtracting 2634 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 28821.4533 with a balance of 0.00026.
