We're dividing 67383021 by 587 
The aim is to understand the frequency of 587 in 67383021.

Let's proceed to step 1:
587 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 587

Let's proceed to step 2:
67 divided by 587 is 0 with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 587

On to step 3:
587 can be fit into 673 1 times, resulting in a remainder of 86.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 86 after subtracting 587 from 673.
Grab the next digit (8) from the dividend, add it to 86, then carry on: 868 / 587

Moving on to step 4:
The number 587 fits into 868 1 times, leaving a remainder of 281.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 587 from 868 to get 281.
Take the next digit (3) from the dividend and append it to 281, then repeat: 2813 / 587

Advancing to step 5:
When dividing 2813 by 587, we get 4 with a remainder of 465.
Put 4 as the next digit of the answer. 
Result so far: 114.0
Deduct 2348 from 2813 and we're left with 465.
Fetch the next digit (0) from the dividend, attach it to 465 and continue: 4650 / 587

Moving on to step 6:
4650 divided by 587 is 7 with a remainder of 541.
Record the quotient 7 as the next digit in the result. 
Result so far: 1147.0
Deduct 4109 from 4650 and we're left with 541.
Take the next digit (2) from the dividend and append it to 541, then repeat: 5412 / 587

On to step 7:
5412 divided by 587 is 9 with a remainder of 129.
Put 9 as the next digit of the answer. 
Result so far: 11479.0
The remainder is 129 after subtracting 5283 from 5412.
Append the next digit (1) from the dividend to 129 and continue with: 1291 / 587

Step 8:
When dividing 1291 by 587, we get 2 with a remainder of 117.
Use 2 as the next digit of our solution. 
Result so far: 114792.0
The remainder is 117 after subtracting 1174 from 1291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 9:
587 goes into 1170 1 times with a remainder of 583.
Write down 1 as next digit of the result. 
Result so far: 114792.1
Subtract 587 from 1170 to get 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Step 10:
The number 587 fits into 5830 9 times, leaving a remainder of 547.
The next digit of our result is 9. 
Result so far: 114792.19
The remainder is 547 after subtracting 5283 from 5830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Moving on to step 11:
If we divide 5470 by 587, we get 9 and a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 114792.199
If we subtract 5283 from 5470, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

The final result is 114792.199 with a remainder of 0.0187.
