We're dividing 75603538 by 248 
The aim is to understand the frequency of 248 in 75603538.

On to step 1:
If we divide 7 by 248, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 248

Step 2:
248 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 75, we get 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 248

Advancing to step 3:
248 goes into 756 3 times with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 744 away from 756, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 248

Advancing to step 4:
248 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 120 and we're left with 120.
Grab the next digit (3) from the dividend, add it to 120, then carry on: 1203 / 248

Advancing to step 5:
The number 248 fits into 1203 4 times, leaving a remainder of 211.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
Subtract 992 from 1203 to get 211.
Append the next digit (5) from the dividend to 211 and continue with: 2115 / 248

Moving on to step 6:
If we divide 2115 by 248, we get 8 and a remainder of 131.
The next digit of our result is 8. 
Result so far: 3048.0
Subtract 1984 from 2115 to get 131.
Grab the next digit (3) from the dividend, add it to 131, then carry on: 1313 / 248

Moving on to step 7:
If we divide 1313 by 248, we get 5 and a remainder of 73.
Use 5 as the next digit of our solution. 
Result so far: 30485.0
If we subtract 1240 from 1313, we get 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 248

Let's proceed to step 8:
248 can be fit into 738 2 times, resulting in a remainder of 242.
The number 2 becomes the next digit in our result. 
Result so far: 304852.0
The remainder is 242 after subtracting 496 from 738.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Going ahead to step 9:
If we divide 2420 by 248, we get 9 and a remainder of 188.
Put 9 as the next digit of the answer. 
Result so far: 304852.9
The remainder is 188 after subtracting 2232 from 2420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 10:
The number 248 fits into 1880 7 times, leaving a remainder of 144.
The number 7 becomes the next digit in our result. 
Result so far: 304852.97
Subtracting 1736 from 1880 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.

On to step 11:
If we divide 1440 by 248, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 304852.975
If we take 1240 away from 1440, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 12:
2000 divided by 248 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 304852.9758
Subtracting 1984 from 2000 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
248 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 304852.9758
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
248 can be fit into 1600 6 times, resulting in a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 304852.975806
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.

Going ahead to step 15:
1120 divided by 248 is 4 with a remainder of 128.
The next digit of our result is 4. 
Result so far: 304852.9758064
Deduct 992 from 1120 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 16:
1280 divided by 248 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 304852.97580645
If we take 1240 away from 1280, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 304852.97580645, and the remainder is 4e-08.
