17100409 ÷ 248 
The aim is to understand the frequency of 248 in 17100409.

Let's proceed to step 1:
1 divided by 248 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 248

Let's proceed to step 2:
248 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 248

Step 3:
The number 248 fits into 171 0 times, leaving a remainder of 171.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 171 after subtracting 0 from 171.
Grab the next digit (0) from the dividend, add it to 171, then carry on: 1710 / 248

Moving on to step 4:
When dividing 1710 by 248, we get 6 with a remainder of 222.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 1488 from 1710 to get 222.
Take the next digit (0) from the dividend and append it to 222, then repeat: 2220 / 248

Going ahead to step 5:
If we divide 2220 by 248, we get 8 and a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Deduct 1984 from 2220 and we're left with 236.
Fetch the next digit (4) from the dividend, attach it to 236 and continue: 2364 / 248

Moving on to step 6:
If we divide 2364 by 248, we get 9 and a remainder of 132.
The next digit of our result is 9. 
Result so far: 689.0
Subtract 2232 from 2364 to get 132.
Include the next digit (0) from the dividend after 132, then repeat: 1320 / 248

Going ahead to step 7:
When dividing 1320 by 248, we get 5 with a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 6895.0
The remainder is 80 after subtracting 1240 from 1320.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 248

Step 8:
The number 248 fits into 809 3 times, leaving a remainder of 65.
Use 3 as the next digit of our solution. 
Result so far: 68953.0
Deduct 744 from 809 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
If we divide 650 by 248, we get 2 and a remainder of 154.
Use 2 as the next digit of our solution. 
Result so far: 68953.2
Subtracting 496 from 650 leaves us with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 10:
248 goes into 1540 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 68953.26
If we take 1488 away from 1540, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
If we divide 520 by 248, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 68953.262
If we subtract 496 from 520, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
The number 248 fits into 240 0 times, leaving a remainder of 240.
Write down 0 as next digit of the result. 
Result so far: 68953.262
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
When dividing 2400 by 248, we get 9 with a remainder of 168.
The number 9 becomes the next digit in our result. 
Result so far: 68953.26209
Subtracting 2232 from 2400 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 14:
248 goes into 1680 6 times with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 68953.262096
Deduct 1488 from 1680 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 15:
The number 248 fits into 1920 7 times, leaving a remainder of 184.
Put 7 as the next digit of the answer. 
Result so far: 68953.2620967
If we take 1736 away from 1920, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 16:
When dividing 1840 by 248, we get 7 with a remainder of 104.
The next digit of our result is 7. 
Result so far: 68953.26209677
Deduct 1736 from 1840 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

In conclusion, the division gives 68953.26209677 with a balance of 1.04e-07.
