763255 ÷ 38 
The aim is to understand the frequency of 38 in 763255.

Going ahead to step 1:
38 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 38

Advancing to step 2:
38 goes into 76 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 76 from 76 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 38

Moving on to step 3:
If we divide 3 by 38, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 38

Going ahead to step 4:
32 divided by 38 is 0 with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 200.0
If we subtract 0 from 32, we get 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 38

On to step 5:
The number 38 fits into 325 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 2008.0
Subtract 304 from 325 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 38

Step 6:
38 goes into 215 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 20085.0
Subtracting 190 from 215 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
When dividing 250 by 38, we get 6 with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 20085.6
Subtracting 228 from 250 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
If we divide 220 by 38, we get 5 and a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 20085.65
The remainder is 30 after subtracting 190 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
The number 38 fits into 300 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 20085.657
Deduct 266 from 300 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
38 can be fit into 340 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 20085.6578
If we subtract 304 from 340, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
When dividing 360 by 38, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 20085.65789
If we take 342 away from 360, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 12:
38 can be fit into 180 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 20085.657894
If we subtract 152 from 180, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
38 goes into 280 7 times with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 20085.6578947
Subtract 266 from 280 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
38 goes into 140 3 times with a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 20085.65789473
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 20085.65789473 and a remainder of 2.6e-08.
