Let's divide 38187 by 879
The aim is to understand the frequency of 879 in 38187.

Moving on to step 1:
3 divided by 879 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 879

On to step 2:
879 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Grab the next digit (1) from the dividend, add it to 38, then carry on: 381 / 879

Moving on to step 3:
879 can be fit into 381 0 times, resulting in a remainder of 381.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 381 after subtracting 0 from 381.
Grab the next digit (8) from the dividend, add it to 381, then carry on: 3818 / 879

Let's proceed to step 4:
When dividing 3818 by 879, we get 4 with a remainder of 302.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3516 away from 3818, we end up with 302.
Take the next digit (7) from the dividend and append it to 302, then repeat: 3027 / 879

Moving on to step 5:
If we divide 3027 by 879, we get 3 and a remainder of 390.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Deduct 2637 from 3027 and we're left with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 6:
879 goes into 3900 4 times with a remainder of 384.
The next digit of our result is 4. 
Result so far: 43.4
Deduct 3516 from 3900 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 7:
When dividing 3840 by 879, we get 4 with a remainder of 324.
The next digit of our result is 4. 
Result so far: 43.44
The remainder is 324 after subtracting 3516 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Our division results in 43.44 with a remaining 0.324.
