We're dividing 15860900 by 248 
The aim is to understand the frequency of 248 in 15860900.

Moving on to step 1:
When dividing 1 by 248, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 248

Moving on to step 2:
If we divide 15 by 248, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 248

Let's proceed to step 3:
158 divided by 248 is 0 with a remainder of 158.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 158, we end up with 158.
Grab the next digit (6) from the dividend, add it to 158, then carry on: 1586 / 248

Let's proceed to step 4:
If we divide 1586 by 248, we get 6 and a remainder of 98.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 1488 away from 1586, we end up with 98.
Grab the next digit (0) from the dividend, add it to 98, then carry on: 980 / 248

Moving on to step 5:
980 divided by 248 is 3 with a remainder of 236.
The next digit of our result is 3. 
Result so far: 63.0
Deduct 744 from 980 and we're left with 236.
Bring next digit (9) of the dividend behind the 236 and repeat the process: 2369 / 248

On to step 6:
The number 248 fits into 2369 9 times, leaving a remainder of 137.
Record the quotient 9 as the next digit in the result. 
Result so far: 639.0
If we subtract 2232 from 2369, we get 137.
Bring next digit (0) of the dividend behind the 137 and repeat the process: 1370 / 248

Step 7:
If we divide 1370 by 248, we get 5 and a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 6395.0
Deduct 1240 from 1370 and we're left with 130.
Include the next digit (0) from the dividend after 130, then repeat: 1300 / 248

Moving on to step 8:
1300 divided by 248 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 63955.0
Subtracting 1240 from 1300 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
600 divided by 248 is 2 with a remainder of 104.
Write down 2 as next digit of the result. 
Result so far: 63955.2
Subtract 496 from 600 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 10:
248 can be fit into 1040 4 times, resulting in a remainder of 48.
The next digit of our result is 4. 
Result so far: 63955.24
Deduct 992 from 1040 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
480 divided by 248 is 1 with a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 63955.241
Subtract 248 from 480 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
248 can be fit into 2320 9 times, resulting in a remainder of 88.
Put 9 as the next digit of the answer. 
Result so far: 63955.2419
Subtracting 2232 from 2320 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 13:
880 divided by 248 is 3 with a remainder of 136.
The next digit of our result is 3. 
Result so far: 63955.24193
Subtract 744 from 880 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 14:
The number 248 fits into 1360 5 times, leaving a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 63955.241935
Deduct 1240 from 1360 and we're left with 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 15:
248 goes into 1200 4 times with a remainder of 208.
Record the quotient 4 as the next digit in the result. 
Result so far: 63955.2419354
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 16:
2080 divided by 248 is 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 63955.24193548
The remainder is 96 after subtracting 1984 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 63955.24193548, and the remainder is 9.6e-08.
