Let's divide 25897780 by 902
The aim is to understand the frequency of 902 in 25897780.

Going ahead to step 1:
The number 902 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 902

Going ahead to step 2:
902 goes into 25 0 times with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 902

Moving on to step 3:
The number 902 fits into 258 0 times, leaving a remainder of 258.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 258 leaves us with 258.
Take the next digit (9) from the dividend and append it to 258, then repeat: 2589 / 902

Let's proceed to step 4:
902 goes into 2589 2 times with a remainder of 785.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 1804 from 2589, we get 785.
Grab the next digit (7) from the dividend, add it to 785, then carry on: 7857 / 902

On to step 5:
The number 902 fits into 7857 8 times, leaving a remainder of 641.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 7216 from 7857 to get 641.
Bring next digit (7) of the dividend behind the 641 and repeat the process: 6417 / 902

Going ahead to step 6:
902 goes into 6417 7 times with a remainder of 103.
Write down 7 as next digit of the result. 
Result so far: 287.0
Subtract 6314 from 6417 to get 103.
Append the next digit (8) from the dividend to 103 and continue with: 1038 / 902

Step 7:
902 goes into 1038 1 times with a remainder of 136.
Record the quotient 1 as the next digit in the result. 
Result so far: 2871.0
Deduct 902 from 1038 and we're left with 136.
Take the next digit (0) from the dividend and append it to 136, then repeat: 1360 / 902

Moving on to step 8:
When dividing 1360 by 902, we get 1 with a remainder of 458.
Put 1 as the next digit of the answer. 
Result so far: 28711.0
Deduct 902 from 1360 and we're left with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 9:
902 can be fit into 4580 5 times, resulting in a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 28711.5
If we take 4510 away from 4580, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 10:
The number 902 fits into 700 0 times, leaving a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 28711.5
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
When dividing 7000 by 902, we get 7 with a remainder of 686.
The number 7 becomes the next digit in our result. 
Result so far: 28711.507
Subtract 6314 from 7000 to get 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

On to step 12:
When dividing 6860 by 902, we get 7 with a remainder of 546.
Record the quotient 7 as the next digit in the result. 
Result so far: 28711.5077
Deduct 6314 from 6860 and we're left with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

In conclusion, the division gives 28711.5077 with a balance of 0.00546.
