3497206 ÷ 251 
The aim is to understand the frequency of 251 in 3497206.

On to step 1:
If we divide 3 by 251, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 251

Step 2:
251 can be fit into 34 0 times, resulting in a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (9) from the dividend and append it to 34, then repeat: 349 / 251

Moving on to step 3:
251 goes into 349 1 times with a remainder of 98.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 251 from 349 leaves us with 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 251

On to step 4:
251 goes into 987 3 times with a remainder of 234.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 753 from 987 leaves us with 234.
Include the next digit (2) from the dividend after 234, then repeat: 2342 / 251

On to step 5:
251 goes into 2342 9 times with a remainder of 83.
Record the quotient 9 as the next digit in the result. 
Result so far: 139.0
If we subtract 2259 from 2342, we get 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 251

Going ahead to step 6:
251 goes into 830 3 times with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 1393.0
If we subtract 753 from 830, we get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 251

Going ahead to step 7:
The number 251 fits into 776 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 13933.0
If we subtract 753 from 776, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 8:
If we divide 230 by 251, we get 0 and a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 13933.0
If we subtract 0 from 230, we get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 9:
251 can be fit into 2300 9 times, resulting in a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 13933.09
Subtract 2259 from 2300 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
251 goes into 410 1 times with a remainder of 159.
Record the quotient 1 as the next digit in the result. 
Result so far: 13933.091
If we subtract 251 from 410, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Step 11:
251 can be fit into 1590 6 times, resulting in a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 13933.0916
Subtract 1506 from 1590 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 12:
251 can be fit into 840 3 times, resulting in a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 13933.09163
If we subtract 753 from 840, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 13:
251 goes into 870 3 times with a remainder of 117.
Use 3 as the next digit of our solution. 
Result so far: 13933.091633
Subtracting 753 from 870 leaves us with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

After the division, we end up with 13933.091633 and a remainder of 1.17e-05.
