We're dividing 25656087 by 237 
The aim is to understand the frequency of 237 in 25656087.

Step 1:
When dividing 2 by 237, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 237

On to step 2:
The number 237 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (6) from the dividend, add it to 25, then carry on: 256 / 237

Advancing to step 3:
If we divide 256 by 237, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 237 from 256 leaves us with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 237

Advancing to step 4:
If we divide 195 by 237, we get 0 and a remainder of 195.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 195 after subtracting 0 from 195.
Fetch the next digit (6) from the dividend, attach it to 195 and continue: 1956 / 237

Advancing to step 5:
The number 237 fits into 1956 8 times, leaving a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 108.0
The remainder is 60 after subtracting 1896 from 1956.
Fetch the next digit (0) from the dividend, attach it to 60 and continue: 600 / 237

Going ahead to step 6:
237 can be fit into 600 2 times, resulting in a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 1082.0
The remainder is 126 after subtracting 474 from 600.
Bring next digit (8) of the dividend behind the 126 and repeat the process: 1268 / 237

Going ahead to step 7:
The number 237 fits into 1268 5 times, leaving a remainder of 83.
Put 5 as the next digit of the answer. 
Result so far: 10825.0
If we take 1185 away from 1268, we end up with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 237

On to step 8:
237 goes into 837 3 times with a remainder of 126.
Write down 3 as next digit of the result. 
Result so far: 108253.0
Subtracting 711 from 837 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 9:
If we divide 1260 by 237, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 108253.5
If we subtract 1185 from 1260, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
When dividing 750 by 237, we get 3 with a remainder of 39.
The next digit of our result is 3. 
Result so far: 108253.53
Subtracting 711 from 750 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 11:
The number 237 fits into 390 1 times, leaving a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 108253.531
Subtracting 237 from 390 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 12:
If we divide 1530 by 237, we get 6 and a remainder of 108.
Put 6 as the next digit of the answer. 
Result so far: 108253.5316
Deduct 1422 from 1530 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 13:
1080 divided by 237 is 4 with a remainder of 132.
The number 4 becomes the next digit in our result. 
Result so far: 108253.53164
Subtract 948 from 1080 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 14:
237 goes into 1320 5 times with a remainder of 135.
The next digit of our result is 5. 
Result so far: 108253.531645
Deduct 1185 from 1320 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 15:
237 can be fit into 1350 5 times, resulting in a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 108253.5316455
Subtracting 1185 from 1350 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

After the division, we end up with 108253.5316455 and a remainder of 1.65e-06.
