We divide 378588 by 71
The aim is to understand the frequency of 71 in 378588.

Advancing to step 1:
If we divide 3 by 71, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 71

Going ahead to step 2:
The number 71 fits into 37 0 times, leaving a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 71

Let's proceed to step 3:
71 goes into 378 5 times with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 355 from 378 and we're left with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 71

On to step 4:
The number 71 fits into 235 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 53.0
If we subtract 213 from 235, we get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 71

Let's proceed to step 5:
71 can be fit into 228 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 533.0
If we take 213 away from 228, we end up with 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 71

Moving on to step 6:
71 can be fit into 158 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 5332.0
Subtracting 142 from 158 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
160 divided by 71 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 5332.2
Subtract 142 from 160 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
71 can be fit into 180 2 times, resulting in a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 5332.22
If we take 142 away from 180, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 5332.22 with a remaining 0.038.
