We're dividing 9581753 by 248 
The aim is to understand the frequency of 248 in 9581753.

Step 1:
248 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 248

Going ahead to step 2:
The number 248 fits into 95 0 times, leaving a remainder of 95.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 95 leaves us with 95.
Fetch the next digit (8) from the dividend, attach it to 95 and continue: 958 / 248

Step 3:
248 goes into 958 3 times with a remainder of 214.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 744 from 958 and we're left with 214.
Grab the next digit (1) from the dividend, add it to 214, then carry on: 2141 / 248

Let's proceed to step 4:
2141 divided by 248 is 8 with a remainder of 157.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 1984 away from 2141, we end up with 157.
Grab the next digit (7) from the dividend, add it to 157, then carry on: 1577 / 248

On to step 5:
If we divide 1577 by 248, we get 6 and a remainder of 89.
The next digit of our result is 6. 
Result so far: 386.0
Subtracting 1488 from 1577 leaves us with 89.
Bring next digit (5) of the dividend behind the 89 and repeat the process: 895 / 248

Step 6:
248 can be fit into 895 3 times, resulting in a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 3863.0
Subtract 744 from 895 to get 151.
Take the next digit (3) from the dividend and append it to 151, then repeat: 1513 / 248

Going ahead to step 7:
248 goes into 1513 6 times with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 38636.0
The remainder is 25 after subtracting 1488 from 1513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
250 divided by 248 is 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 38636.1
If we subtract 248 from 250, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 248 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 38636.1
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 248 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 38636.1
Deduct 0 from 200 and we're left 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.

The quotient of the division is 38636.1, and the remainder is 0.02.
