58764503 divided by 248 
The aim is to understand the frequency of 248 in 58764503.

On to step 1:
5 divided by 248 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 248

On to step 2:
If we divide 58 by 248, we get 0 and a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Grab the next digit (7) from the dividend, add it to 58, then carry on: 587 / 248

Step 3:
If we divide 587 by 248, we get 2 and a remainder of 91.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 496 from 587 to get 91.
Include the next digit (6) from the dividend after 91, then repeat: 916 / 248

Let's proceed to step 4:
If we divide 916 by 248, we get 3 and a remainder of 172.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 744 from 916 and we're left with 172.
Fetch the next digit (4) from the dividend, attach it to 172 and continue: 1724 / 248

Step 5:
1724 divided by 248 is 6 with a remainder of 236.
Put 6 as the next digit of the answer. 
Result so far: 236.0
Deduct 1488 from 1724 and we're left with 236.
Append the next digit (5) from the dividend to 236 and continue with: 2365 / 248

Let's proceed to step 6:
When dividing 2365 by 248, we get 9 with a remainder of 133.
Put 9 as the next digit of the answer. 
Result so far: 2369.0
The remainder is 133 after subtracting 2232 from 2365.
Append the next digit (0) from the dividend to 133 and continue with: 1330 / 248

Advancing to step 7:
248 goes into 1330 5 times with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 23695.0
Subtract 1240 from 1330 to get 90.
Grab the next digit (3) from the dividend, add it to 90, then carry on: 903 / 248

Step 8:
The number 248 fits into 903 3 times, leaving a remainder of 159.
The next digit of our result is 3. 
Result so far: 236953.0
The remainder is 159 after subtracting 744 from 903.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 9:
When dividing 1590 by 248, we get 6 with a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 236953.6
If we take 1488 away from 1590, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
1020 divided by 248 is 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 236953.64
If we subtract 992 from 1020, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
280 divided by 248 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 236953.641
The remainder is 32 after subtracting 248 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
If we divide 320 by 248, we get 1 and a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 236953.6411
The remainder is 72 after subtracting 248 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

After the division, we end up with 236953.6411 and a remainder of 0.00072.
