We divide 18387481 by 487
The aim is to understand the frequency of 487 in 18387481.

Advancing to step 1:
If we divide 1 by 487, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 487

On to step 2:
If we divide 18 by 487, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 487

On to step 3:
The number 487 fits into 183 0 times, leaving a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 183 to get 183.
Fetch the next digit (8) from the dividend, attach it to 183 and continue: 1838 / 487

Advancing to step 4:
If we divide 1838 by 487, we get 3 and a remainder of 377.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 377 after subtracting 1461 from 1838.
Include the next digit (7) from the dividend after 377, then repeat: 3777 / 487

Advancing to step 5:
487 goes into 3777 7 times with a remainder of 368.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we take 3409 away from 3777, we end up with 368.
Take the next digit (4) from the dividend and append it to 368, then repeat: 3684 / 487

Advancing to step 6:
The number 487 fits into 3684 7 times, leaving a remainder of 275.
The number 7 becomes the next digit in our result. 
Result so far: 377.0
The remainder is 275 after subtracting 3409 from 3684.
Bring next digit (8) of the dividend behind the 275 and repeat the process: 2758 / 487

Step 7:
2758 divided by 487 is 5 with a remainder of 323.
The number 5 becomes the next digit in our result. 
Result so far: 3775.0
Subtracting 2435 from 2758 leaves us with 323.
Fetch the next digit (1) from the dividend, attach it to 323 and continue: 3231 / 487

Going ahead to step 8:
When dividing 3231 by 487, we get 6 with a remainder of 309.
The next digit of our result is 6. 
Result so far: 37756.0
If we subtract 2922 from 3231, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 9:
When dividing 3090 by 487, we get 6 with a remainder of 168.
Record the quotient 6 as the next digit in the result. 
Result so far: 37756.6
The remainder is 168 after subtracting 2922 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 10:
487 can be fit into 1680 3 times, resulting in a remainder of 219.
Record the quotient 3 as the next digit in the result. 
Result so far: 37756.63
If we take 1461 away from 1680, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 11:
2190 divided by 487 is 4 with a remainder of 242.
The number 4 becomes the next digit in our result. 
Result so far: 37756.634
If we subtract 1948 from 2190, we get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 12:
487 can be fit into 2420 4 times, resulting in a remainder of 472.
The number 4 becomes the next digit in our result. 
Result so far: 37756.6344
Subtract 1948 from 2420 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

After the division, we end up with 37756.6344 and a remainder of 0.00472.
