29107578 ÷ 249 
The aim is to understand the frequency of 249 in 29107578.

Let's proceed to step 1:
If we divide 2 by 249, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 249

Advancing to step 2:
When dividing 29 by 249, we get 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Take the next digit (1) from the dividend and append it to 29, then repeat: 291 / 249

On to step 3:
291 divided by 249 is 1 with a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 249 away from 291, we end up with 42.
Grab the next digit (0) from the dividend, add it to 42, then carry on: 420 / 249

Going ahead to step 4:
The number 249 fits into 420 1 times, leaving a remainder of 171.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 171 after subtracting 249 from 420.
Bring next digit (7) of the dividend behind the 171 and repeat the process: 1717 / 249

Step 5:
1717 divided by 249 is 6 with a remainder of 223.
The next digit of our result is 6. 
Result so far: 116.0
If we subtract 1494 from 1717, we get 223.
Fetch the next digit (5) from the dividend, attach it to 223 and continue: 2235 / 249

Going ahead to step 6:
If we divide 2235 by 249, we get 8 and a remainder of 243.
The next digit of our result is 8. 
Result so far: 1168.0
Deduct 1992 from 2235 and we're left with 243.
Grab the next digit (7) from the dividend, add it to 243, then carry on: 2437 / 249

Let's proceed to step 7:
249 can be fit into 2437 9 times, resulting in a remainder of 196.
Put 9 as the next digit of the answer. 
Result so far: 11689.0
Deduct 2241 from 2437 and we're left with 196.
Include the next digit (8) from the dividend after 196, then repeat: 1968 / 249

Advancing to step 8:
1968 divided by 249 is 7 with a remainder of 225.
Record the quotient 7 as the next digit in the result. 
Result so far: 116897.0
If we subtract 1743 from 1968, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 9:
When dividing 2250 by 249, we get 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 116897.9
Subtracting 2241 from 2250 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
249 goes into 90 0 times with a remainder of 90.
The next digit of our result is 0. 
Result so far: 116897.9
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
900 divided by 249 is 3 with a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 116897.903
Subtracting 747 from 900 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 12:
When dividing 1530 by 249, we get 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 116897.9036
If we take 1494 away from 1530, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
360 divided by 249 is 1 with a remainder of 111.
The next digit of our result is 1. 
Result so far: 116897.90361
The remainder is 111 after subtracting 249 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 14:
When dividing 1110 by 249, we get 4 with a remainder of 114.
Record the quotient 4 as the next digit in the result. 
Result so far: 116897.903614
Subtract 996 from 1110 to get 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 15:
249 goes into 1140 4 times with a remainder of 144.
The next digit of our result is 4. 
Result so far: 116897.9036144
If we take 996 away from 1140, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 116897.9036144 and a remainder of 1.44e-06.
