We're dividing 668741 by 38 
The aim is to understand the frequency of 38 in 668741.

Going ahead to step 1:
38 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 38

Advancing to step 2:
If we divide 66 by 38, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 38 from 66 to get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 38

Step 3:
The number 38 fits into 288 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 266 away from 288, we end up with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 38

Step 4:
If we divide 227 by 38, we get 5 and a remainder of 37.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Subtract 190 from 227 to get 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 38

Let's proceed to step 5:
38 goes into 374 9 times with a remainder of 32.
The next digit of our result is 9. 
Result so far: 1759.0
If we take 342 away from 374, we end up with 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 38

Moving on to step 6:
If we divide 321 by 38, we get 8 and a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 17598.0
The remainder is 17 after subtracting 304 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
When dividing 170 by 38, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 17598.4
The remainder is 18 after subtracting 152 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
If we divide 180 by 38, we get 4 and a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 17598.44
The remainder is 28 after subtracting 152 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 17598.44, and the remainder is 0.028.
