We're dividing 78236237 by 248 
The aim is to understand the frequency of 248 in 78236237.

Step 1:
The number 248 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 248

Moving on to step 2:
248 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (2) from the dividend to 78 and continue with: 782 / 248

Step 3:
When dividing 782 by 248, we get 3 with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 744 from 782 and we're left with 38.
Include the next digit (3) from the dividend after 38, then repeat: 383 / 248

Step 4:
248 can be fit into 383 1 times, resulting in a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 31.0
Deduct 248 from 383 and we're left with 135.
Fetch the next digit (6) from the dividend, attach it to 135 and continue: 1356 / 248

On to step 5:
1356 divided by 248 is 5 with a remainder of 116.
Write down 5 as next digit of the result. 
Result so far: 315.0
If we take 1240 away from 1356, we end up with 116.
Take the next digit (2) from the dividend and append it to 116, then repeat: 1162 / 248

Moving on to step 6:
248 can be fit into 1162 4 times, resulting in a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 3154.0
If we subtract 992 from 1162, we get 170.
Take the next digit (3) from the dividend and append it to 170, then repeat: 1703 / 248

Advancing to step 7:
If we divide 1703 by 248, we get 6 and a remainder of 215.
The next digit of our result is 6. 
Result so far: 31546.0
If we subtract 1488 from 1703, we get 215.
Take the next digit (7) from the dividend and append it to 215, then repeat: 2157 / 248

Let's proceed to step 8:
2157 divided by 248 is 8 with a remainder of 173.
Use 8 as the next digit of our solution. 
Result so far: 315468.0
The remainder is 173 after subtracting 1984 from 2157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Let's proceed to step 9:
248 can be fit into 1730 6 times, resulting in a remainder of 242.
Write down 6 as next digit of the result. 
Result so far: 315468.6
Subtracting 1488 from 1730 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 10:
248 goes into 2420 9 times with a remainder of 188.
The next digit of our result is 9. 
Result so far: 315468.69
Subtract 2232 from 2420 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
If we divide 1880 by 248, we get 7 and a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 315468.697
If we take 1736 away from 1880, 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.

Moving on to step 12:
When dividing 1440 by 248, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 315468.6975
Subtract 1240 from 1440 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
2000 divided by 248 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 315468.69758
Subtract 1984 from 2000 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 14:
If we divide 160 by 248, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 315468.69758
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 15:
If we divide 1600 by 248, we get 6 and a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 315468.6975806
If we take 1488 away from 1600, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 16:
If we divide 1120 by 248, we get 4 and a remainder of 128.
Record the quotient 4 as the next digit in the result. 
Result so far: 315468.69758064
Subtract 992 from 1120 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The quotient of the division is 315468.69758064, and the remainder is 1.28e-07.
