63101018 divided by 248 
The aim is to understand the frequency of 248 in 63101018.

Step 1:
6 divided by 248 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 248

Let's proceed to step 2:
248 goes into 63 0 times with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 248

Moving on to step 3:
The number 248 fits into 631 2 times, leaving a remainder of 135.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 496 away from 631, we end up with 135.
Take the next digit (0) from the dividend and append it to 135, then repeat: 1350 / 248

On to step 4:
248 can be fit into 1350 5 times, resulting in a remainder of 110.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
The remainder is 110 after subtracting 1240 from 1350.
Bring next digit (1) of the dividend behind the 110 and repeat the process: 1101 / 248

Let's proceed to step 5:
The number 248 fits into 1101 4 times, leaving a remainder of 109.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 992 from 1101 to get 109.
Take the next digit (0) from the dividend and append it to 109, then repeat: 1090 / 248

Let's proceed to step 6:
1090 divided by 248 is 4 with a remainder of 98.
Put 4 as the next digit of the answer. 
Result so far: 2544.0
If we take 992 away from 1090, we end up with 98.
Bring next digit (1) of the dividend behind the 98 and repeat the process: 981 / 248

Moving on to step 7:
248 can be fit into 981 3 times, resulting in a remainder of 237.
The next digit of our result is 3. 
Result so far: 25443.0
Subtracting 744 from 981 leaves us with 237.
Bring next digit (8) of the dividend behind the 237 and repeat the process: 2378 / 248

Moving on to step 8:
The number 248 fits into 2378 9 times, leaving a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 254439.0
If we subtract 2232 from 2378, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 9:
248 can be fit into 1460 5 times, resulting in a remainder of 220.
Put 5 as the next digit of the answer. 
Result so far: 254439.5
The remainder is 220 after subtracting 1240 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

On to step 10:
2200 divided by 248 is 8 with a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 254439.58
Subtracting 1984 from 2200 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.

Advancing to step 11:
When dividing 2160 by 248, we get 8 with a remainder of 176.
Write down 8 as next digit of the result. 
Result so far: 254439.588
If we take 1984 away from 2160, we end up 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 quotient of the division is 254439.588, and the remainder is 0.0176.
