Let's divide 432421 by 38
The aim is to understand the frequency of 38 in 432421.

On to step 1:
When dividing 4 by 38, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 38

Going ahead to step 2:
43 divided by 38 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 38 away from 43, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 38

Going ahead to step 3:
38 can be fit into 52 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 38 away from 52, we end up with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 38

Let's proceed to step 4:
38 goes into 144 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 113.0
Deduct 114 from 144 and we're left with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 38

Let's proceed to step 5:
If we divide 302 by 38, we get 7 and a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 1137.0
The remainder is 36 after subtracting 266 from 302.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 38

Advancing to step 6:
When dividing 361 by 38, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 11379.0
The remainder is 19 after subtracting 342 from 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 38, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11379.5
Subtract 190 from 190 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 38 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11379.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
The number 38 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11379.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 11379.5 with a remaining 0.0.
