We look at the division of 3800249 by 251 
The aim is to understand the frequency of 251 in 3800249.

Going ahead to step 1:
251 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 251

Going ahead to step 2:
When dividing 38 by 251, we get 0 with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 251

Going ahead to step 3:
When dividing 380 by 251, we get 1 with a remainder of 129.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 251 from 380, we get 129.
Include the next digit (0) from the dividend after 129, then repeat: 1290 / 251

Moving on to step 4:
If we divide 1290 by 251, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 1255 away from 1290, we end up with 35.
Fetch the next digit (2) from the dividend, attach it to 35 and continue: 352 / 251

Moving on to step 5:
352 divided by 251 is 1 with a remainder of 101.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we take 251 away from 352, we end up with 101.
Include the next digit (4) from the dividend after 101, then repeat: 1014 / 251

On to step 6:
The number 251 fits into 1014 4 times, leaving a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 1514.0
Subtracting 1004 from 1014 leaves us with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 251

Let's proceed to step 7:
When dividing 109 by 251, we get 0 with a remainder of 109.
Use 0 as the next digit of our solution. 
Result so far: 15140.0
If we take 0 away from 109, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 8:
When dividing 1090 by 251, we get 4 with a remainder of 86.
The next digit of our result is 4. 
Result so far: 15140.4
Subtract 1004 from 1090 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
When dividing 860 by 251, we get 3 with a remainder of 107.
The next digit of our result is 3. 
Result so far: 15140.43
Subtracting 753 from 860 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 10:
When dividing 1070 by 251, we get 4 with a remainder of 66.
Use 4 as the next digit of our solution. 
Result so far: 15140.434
Subtracting 1004 from 1070 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
251 goes into 660 2 times with a remainder of 158.
Write down 2 as next digit of the result. 
Result so far: 15140.4342
Subtract 502 from 660 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Going ahead to step 12:
When dividing 1580 by 251, we get 6 with a remainder of 74.
Record the quotient 6 as the next digit in the result. 
Result so far: 15140.43426
Subtracting 1506 from 1580 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 13:
The number 251 fits into 740 2 times, leaving a remainder of 238.
The next digit of our result is 2. 
Result so far: 15140.434262
If we take 502 away from 740, we end up with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Going ahead to step 14:
2380 divided by 251 is 9 with a remainder of 121.
The number 9 becomes the next digit in our result. 
Result so far: 15140.4342629
The remainder is 121 after subtracting 2259 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 15:
When dividing 1210 by 251, we get 4 with a remainder of 206.
The next digit of our result is 4. 
Result so far: 15140.43426294
If we take 1004 away from 1210, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Our division results in 15140.43426294 with a remaining 2.06e-07.
