79437508 divided by 248 
The aim is to understand the frequency of 248 in 79437508.

Let's proceed to step 1:
When dividing 7 by 248, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 248

Step 2:
79 divided by 248 is 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Append the next digit (4) from the dividend to 79 and continue with: 794 / 248

Step 3:
If we divide 794 by 248, we get 3 and a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 744 away from 794, we end up with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 248

On to step 4:
The number 248 fits into 503 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 32.0
The remainder is 7 after subtracting 496 from 503.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 248

Advancing to step 5:
When dividing 77 by 248, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 320.0
If we take 0 away from 77, we end up with 77.
Fetch the next digit (5) from the dividend, attach it to 77 and continue: 775 / 248

Advancing to step 6:
248 can be fit into 775 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 3203.0
If we subtract 744 from 775, we get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 248

On to step 7:
248 can be fit into 310 1 times, resulting in a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 32031.0
If we take 248 away from 310, we end up with 62.
Grab the next digit (8) from the dividend, add it to 62, then carry on: 628 / 248

Going ahead to step 8:
628 divided by 248 is 2 with a remainder of 132.
The number 2 becomes the next digit in our result. 
Result so far: 320312.0
Deduct 496 from 628 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 9:
The number 248 fits into 1320 5 times, leaving a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 320312.5
If we subtract 1240 from 1320, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 248 is 3 with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 320312.53
Subtracting 744 from 800 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 11:
When dividing 560 by 248, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 320312.532
Subtract 496 from 560 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
640 divided by 248 is 2 with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 320312.5322
Subtracting 496 from 640 leaves us 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.

Our division results in 320312.5322 with a remaining 0.00144.
