We look at the division of 27170090 by 249 
The aim is to understand the frequency of 249 in 27170090.

Let's proceed to step 1:
249 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 249

Let's proceed to step 2:
249 goes into 27 0 times with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 249

Moving on to step 3:
271 divided by 249 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 249 from 271, we get 22.
Fetch the next digit (7) from the dividend, attach it to 22 and continue: 227 / 249

Moving on to step 4:
The number 249 fits into 227 0 times, leaving a remainder of 227.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 227 after subtracting 0 from 227.
Take the next digit (0) from the dividend and append it to 227, then repeat: 2270 / 249

On to step 5:
249 can be fit into 2270 9 times, resulting in a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 2241 from 2270, we get 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 249

Going ahead to step 6:
249 can be fit into 290 1 times, resulting in a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1091.0
Subtract 249 from 290 to get 41.
Take the next digit (9) from the dividend and append it to 41, then repeat: 419 / 249

Let's proceed to step 7:
419 divided by 249 is 1 with a remainder of 170.
The next digit of our result is 1. 
Result so far: 10911.0
Deduct 249 from 419 and we're left with 170.
Bring next digit (0) of the dividend behind the 170 and repeat the process: 1700 / 249

Moving on to step 8:
249 can be fit into 1700 6 times, resulting in a remainder of 206.
Record the quotient 6 as the next digit in the result. 
Result so far: 109116.0
Subtract 1494 from 1700 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 9:
249 goes into 2060 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 109116.8
If we subtract 1992 from 2060, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
The number 249 fits into 680 2 times, leaving a remainder of 182.
The number 2 becomes the next digit in our result. 
Result so far: 109116.82
Subtract 498 from 680 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 11:
1820 divided by 249 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 109116.827
Subtracting 1743 from 1820 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 12:
The number 249 fits into 770 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 109116.8273
If we take 747 away from 770, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
When dividing 230 by 249, we get 0 with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 109116.8273
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.

Moving on to step 14:
The number 249 fits into 2300 9 times, leaving a remainder of 59.
The next digit of our result is 9. 
Result so far: 109116.827309
The remainder is 59 after subtracting 2241 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 15:
249 goes into 590 2 times with a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 109116.8273092
Subtracting 498 from 590 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 16:
249 can be fit into 920 3 times, resulting in a remainder of 173.
Record the quotient 3 as the next digit in the result. 
Result so far: 109116.82730923
Deduct 747 from 920 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

After the division, we end up with 109116.82730923 and a remainder of 1.73e-07.
