We're dividing 25625689 by 837 
The aim is to understand the frequency of 837 in 25625689.

On to step 1:
If we divide 2 by 837, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 837

Moving on to step 2:
When dividing 25 by 837, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 837

Step 3:
If we divide 256 by 837, we get 0 and a remainder of 256.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 256 after subtracting 0 from 256.
Grab the next digit (2) from the dividend, add it to 256, then carry on: 2562 / 837

On to step 4:
When dividing 2562 by 837, we get 3 with a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 2511 from 2562 and we're left with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 837

On to step 5:
837 goes into 515 0 times with a remainder of 515.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtract 0 from 515 to get 515.
Fetch the next digit (6) from the dividend, attach it to 515 and continue: 5156 / 837

Moving on to step 6:
If we divide 5156 by 837, we get 6 and a remainder of 134.
Record the quotient 6 as the next digit in the result. 
Result so far: 306.0
If we subtract 5022 from 5156, we get 134.
Append the next digit (8) from the dividend to 134 and continue with: 1348 / 837

Advancing to step 7:
1348 divided by 837 is 1 with a remainder of 511.
Use 1 as the next digit of our solution. 
Result so far: 3061.0
Subtracting 837 from 1348 leaves us with 511.
Append the next digit (9) from the dividend to 511 and continue with: 5119 / 837

Advancing to step 8:
837 goes into 5119 6 times with a remainder of 97.
Put 6 as the next digit of the answer. 
Result so far: 30616.0
Deduct 5022 from 5119 and we're left with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
970 divided by 837 is 1 with a remainder of 133.
Write down 1 as next digit of the result. 
Result so far: 30616.1
If we subtract 837 from 970, we get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Going ahead to step 10:
If we divide 1330 by 837, we get 1 and a remainder of 493.
Put 1 as the next digit of the answer. 
Result so far: 30616.11
Subtracting 837 from 1330 leaves us with 493.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

In conclusion, the division gives 30616.11 with a balance of 0.493.
