72551 ÷ 38 
The aim is to understand the frequency of 38 in 72551.

Advancing to step 1:
If we divide 7 by 38, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 38

Moving on to step 2:
72 divided by 38 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 38 from 72 to get 34.
Take the next digit (5) from the dividend and append it to 34, then repeat: 345 / 38

On to step 3:
When dividing 345 by 38, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 342 from 345 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 38

Advancing to step 4:
When dividing 35 by 38, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
If we subtract 0 from 35, we get 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 38

Moving on to step 5:
If we divide 351 by 38, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 1909.0
If we subtract 342 from 351, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 6:
90 divided by 38 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1909.2
If we take 76 away from 90, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 38 is 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 1909.23
Subtract 114 from 140 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
The number 38 fits into 260 6 times, leaving a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1909.236
If we subtract 228 from 260, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1909.2368
Deduct 304 from 320 and we're left 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.

Going ahead to step 10:
If we divide 160 by 38, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 1909.23684
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
38 goes into 80 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1909.236842
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 38 is 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1909.2368421
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
38 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1909.2368421
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 1909.2368421, and the remainder is 2e-08.
