We divide 20738930 by 487
The aim is to understand the frequency of 487 in 20738930.

Advancing to step 1:
487 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 487

On to step 2:
When dividing 20 by 487, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 487

On to step 3:
487 goes into 207 0 times with a remainder of 207.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 207 after subtracting 0 from 207.
Fetch the next digit (3) from the dividend, attach it to 207 and continue: 2073 / 487

On to step 4:
The number 487 fits into 2073 4 times, leaving a remainder of 125.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 125 after subtracting 1948 from 2073.
Take the next digit (8) from the dividend and append it to 125, then repeat: 1258 / 487

Let's proceed to step 5:
1258 divided by 487 is 2 with a remainder of 284.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
If we subtract 974 from 1258, we get 284.
Include the next digit (9) from the dividend after 284, then repeat: 2849 / 487

Going ahead to step 6:
When dividing 2849 by 487, we get 5 with a remainder of 414.
Record the quotient 5 as the next digit in the result. 
Result so far: 425.0
The remainder is 414 after subtracting 2435 from 2849.
Bring next digit (3) of the dividend behind the 414 and repeat the process: 4143 / 487

Moving on to step 7:
When dividing 4143 by 487, we get 8 with a remainder of 247.
Use 8 as the next digit of our solution. 
Result so far: 4258.0
Deduct 3896 from 4143 and we're left with 247.
Grab the next digit (0) from the dividend, add it to 247, then carry on: 2470 / 487

Going ahead to step 8:
The number 487 fits into 2470 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 42585.0
If we take 2435 away from 2470, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 487 fits into 350 0 times, leaving a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 42585.0
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 10:
When dividing 3500 by 487, we get 7 with a remainder of 91.
The number 7 becomes the next digit in our result. 
Result so far: 42585.07
Subtracting 3409 from 3500 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Let's proceed to step 11:
If we divide 910 by 487, we get 1 and a remainder of 423.
Put 1 as the next digit of the answer. 
Result so far: 42585.071
Subtract 487 from 910 to get 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 12:
487 goes into 4230 8 times with a remainder of 334.
Put 8 as the next digit of the answer. 
Result so far: 42585.0718
Subtract 3896 from 4230 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

On to step 13:
3340 divided by 487 is 6 with a remainder of 418.
Put 6 as the next digit of the answer. 
Result so far: 42585.07186
If we subtract 2922 from 3340, we get 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 14:
487 goes into 4180 8 times with a remainder of 284.
Use 8 as the next digit of our solution. 
Result so far: 42585.071868
Subtracting 3896 from 4180 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 15:
The number 487 fits into 2840 5 times, leaving a remainder of 405.
The number 5 becomes the next digit in our result. 
Result so far: 42585.0718685
The remainder is 405 after subtracting 2435 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Going ahead to step 16:
When dividing 4050 by 487, we get 8 with a remainder of 154.
Record the quotient 8 as the next digit in the result. 
Result so far: 42585.07186858
Subtract 3896 from 4050 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Our division results in 42585.07186858 with a remaining 1.54e-07.
