26642790 ÷ 248 
The aim is to understand the frequency of 248 in 26642790.

Let's proceed to step 1:
If we divide 2 by 248, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 248

Going ahead to step 2:
248 can be fit into 26 0 times, resulting in a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 248

On to step 3:
The number 248 fits into 266 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 248 from 266 leaves us with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 248

Going ahead to step 4:
248 goes into 184 0 times with a remainder of 184.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 184 and we're left with 184.
Append the next digit (2) from the dividend to 184 and continue with: 1842 / 248

Moving on to step 5:
When dividing 1842 by 248, we get 7 with a remainder of 106.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtracting 1736 from 1842 leaves us with 106.
Append the next digit (7) from the dividend to 106 and continue with: 1067 / 248

Advancing to step 6:
If we divide 1067 by 248, we get 4 and a remainder of 75.
Record the quotient 4 as the next digit in the result. 
Result so far: 1074.0
Subtract 992 from 1067 to get 75.
Bring next digit (9) of the dividend behind the 75 and repeat the process: 759 / 248

Moving on to step 7:
759 divided by 248 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 10743.0
Subtract 744 from 759 to get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 248

Let's proceed to step 8:
248 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 107430.0
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
The number 248 fits into 1500 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 107430.6
Subtracting 1488 from 1500 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
The number 248 fits into 120 0 times, leaving a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 107430.6
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
If we divide 1200 by 248, we get 4 and a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 107430.604
Subtract 992 from 1200 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 12:
If we divide 2080 by 248, we get 8 and a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 107430.6048
If we take 1984 away from 2080, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 13:
248 can be fit into 960 3 times, resulting in a remainder of 216.
The number 3 becomes the next digit in our result. 
Result so far: 107430.60483
The remainder is 216 after subtracting 744 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 14:
When dividing 2160 by 248, we get 8 with a remainder of 176.
The next digit of our result is 8. 
Result so far: 107430.604838
Deduct 1984 from 2160 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 15:
If we divide 1760 by 248, we get 7 and a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 107430.6048387
The remainder is 24 after subtracting 1736 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 16:
240 divided by 248 is 0 with a remainder of 240.
The next digit of our result is 0. 
Result so far: 107430.6048387
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 107430.6048387 and a remainder of 2.4e-07.
