We look at the division of 36357778 by 248 
The aim is to understand the frequency of 248 in 36357778.

Step 1:
248 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 248

Let's proceed to step 2:
36 divided by 248 is 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 248

Step 3:
If we divide 363 by 248, we get 1 and a remainder of 115.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 115 after subtracting 248 from 363.
Append the next digit (5) from the dividend to 115 and continue with: 1155 / 248

On to step 4:
1155 divided by 248 is 4 with a remainder of 163.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 992 away from 1155, we end up with 163.
Fetch the next digit (7) from the dividend, attach it to 163 and continue: 1637 / 248

Let's proceed to step 5:
1637 divided by 248 is 6 with a remainder of 149.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Subtracting 1488 from 1637 leaves us with 149.
Append the next digit (7) from the dividend to 149 and continue with: 1497 / 248

Moving on to step 6:
If we divide 1497 by 248, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 1466.0
If we subtract 1488 from 1497, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 248

Step 7:
The number 248 fits into 97 0 times, leaving a remainder of 97.
Record the quotient 0 as the next digit in the result. 
Result so far: 14660.0
The remainder is 97 after subtracting 0 from 97.
Bring next digit (8) of the dividend behind the 97 and repeat the process: 978 / 248

Let's proceed to step 8:
The number 248 fits into 978 3 times, leaving a remainder of 234.
Use 3 as the next digit of our solution. 
Result so far: 146603.0
The remainder is 234 after subtracting 744 from 978.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 9:
248 goes into 2340 9 times with a remainder of 108.
Put 9 as the next digit of the answer. 
Result so far: 146603.9
The remainder is 108 after subtracting 2232 from 2340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 10:
If we divide 1080 by 248, we get 4 and a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 146603.94
Subtract 992 from 1080 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 11:
248 goes into 880 3 times with a remainder of 136.
Write down 3 as next digit of the result. 
Result so far: 146603.943
Deduct 744 from 880 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
When dividing 1360 by 248, we get 5 with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 146603.9435
Subtract 1240 from 1360 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.

Going ahead to step 13:
248 goes into 1200 4 times with a remainder of 208.
Write down 4 as next digit of the result. 
Result so far: 146603.94354
Deduct 992 from 1200 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 14:
When dividing 2080 by 248, we get 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 146603.943548
Subtracting 1984 from 2080 leaves us 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 15:
When dividing 960 by 248, we get 3 with a remainder of 216.
Record the quotient 3 as the next digit in the result. 
Result so far: 146603.9435483
Subtracting 744 from 960 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 16:
When dividing 2160 by 248, we get 8 with a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 146603.94354838
Subtracting 1984 from 2160 leaves us 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.

The final outcome is 146603.94354838, with a leftover of 1.76e-07.
