Let's divide 18259371 by 657
The aim is to understand the frequency of 657 in 18259371.

Advancing to step 1:
657 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 657

Advancing to step 2:
657 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 657

Advancing to step 3:
The number 657 fits into 182 0 times, leaving a remainder of 182.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 182 and we're left with 182.
Append the next digit (5) from the dividend to 182 and continue with: 1825 / 657

Step 4:
657 can be fit into 1825 2 times, resulting in a remainder of 511.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1314 away from 1825, we end up with 511.
Bring next digit (9) of the dividend behind the 511 and repeat the process: 5119 / 657

On to step 5:
657 can be fit into 5119 7 times, resulting in a remainder of 520.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Deduct 4599 from 5119 and we're left with 520.
Include the next digit (3) from the dividend after 520, then repeat: 5203 / 657

Let's proceed to step 6:
When dividing 5203 by 657, we get 7 with a remainder of 604.
Write down 7 as next digit of the result. 
Result so far: 277.0
Subtract 4599 from 5203 to get 604.
Grab the next digit (7) from the dividend, add it to 604, then carry on: 6047 / 657

Let's proceed to step 7:
If we divide 6047 by 657, we get 9 and a remainder of 134.
Put 9 as the next digit of the answer. 
Result so far: 2779.0
If we subtract 5913 from 6047, we get 134.
Include the next digit (1) from the dividend after 134, then repeat: 1341 / 657

Let's proceed to step 8:
657 can be fit into 1341 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 27792.0
If we take 1314 away from 1341, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 9:
657 can be fit into 270 0 times, resulting in a remainder of 270.
Put 0 as the next digit of the answer. 
Result so far: 27792.0
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 10:
657 can be fit into 2700 4 times, resulting in a remainder of 72.
The next digit of our result is 4. 
Result so far: 27792.04
Subtracting 2628 from 2700 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
657 can be fit into 720 1 times, resulting in a remainder of 63.
Write down 1 as next digit of the result. 
Result so far: 27792.041
Subtracting 657 from 720 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 12:
657 can be fit into 630 0 times, resulting in a remainder of 630.
The number 0 becomes the next digit in our result. 
Result so far: 27792.041
Deduct 0 from 630 and we're left with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 13:
The number 657 fits into 6300 9 times, leaving a remainder of 387.
Use 9 as the next digit of our solution. 
Result so far: 27792.04109
Deduct 5913 from 6300 and we're left with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

On to step 14:
657 goes into 3870 5 times with a remainder of 585.
The next digit of our result is 5. 
Result so far: 27792.041095
Subtracting 3285 from 3870 leaves us with 585.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Advancing to step 15:
5850 divided by 657 is 8 with a remainder of 594.
The next digit of our result is 8. 
Result so far: 27792.0410958
Subtracting 5256 from 5850 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

Advancing to step 16:
657 can be fit into 5940 9 times, resulting in a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 27792.04109589
If we take 5913 away from 5940, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 27792.04109589 and a remainder of 2.7e-08.
