Let's divide 80122638 by 249
The aim is to understand the frequency of 249 in 80122638.

Step 1:
249 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 249

On to step 2:
When dividing 80 by 249, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Bring next digit (1) of the dividend behind the 80 and repeat the process: 801 / 249

Advancing to step 3:
The number 249 fits into 801 3 times, leaving a remainder of 54.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 747 from 801 and we're left with 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 249

Advancing to step 4:
249 goes into 542 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
Subtracting 498 from 542 leaves us with 44.
Grab the next digit (2) from the dividend, add it to 44, then carry on: 442 / 249

Moving on to step 5:
If we divide 442 by 249, we get 1 and a remainder of 193.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
If we take 249 away from 442, we end up with 193.
Grab the next digit (6) from the dividend, add it to 193, then carry on: 1936 / 249

Advancing to step 6:
249 goes into 1936 7 times with a remainder of 193.
Write down 7 as next digit of the result. 
Result so far: 3217.0
Subtract 1743 from 1936 to get 193.
Fetch the next digit (3) from the dividend, attach it to 193 and continue: 1933 / 249

On to step 7:
When dividing 1933 by 249, we get 7 with a remainder of 190.
Write down 7 as next digit of the result. 
Result so far: 32177.0
If we subtract 1743 from 1933, we get 190.
Bring next digit (8) of the dividend behind the 190 and repeat the process: 1908 / 249

Advancing to step 8:
1908 divided by 249 is 7 with a remainder of 165.
Use 7 as the next digit of our solution. 
Result so far: 321777.0
If we take 1743 away from 1908, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 9:
249 can be fit into 1650 6 times, resulting in a remainder of 156.
Record the quotient 6 as the next digit in the result. 
Result so far: 321777.6
If we take 1494 away from 1650, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 10:
1560 divided by 249 is 6 with a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 321777.66
Subtracting 1494 from 1560 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 321777.66 and a remainder of 0.066.
