Let's divide 7186483 by 248
The aim is to understand the frequency of 248 in 7186483.

On to step 1:
When dividing 7 by 248, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 248

Let's proceed to step 2:
When dividing 71 by 248, we get 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (8) from the dividend, attach it to 71 and continue: 718 / 248

Advancing to step 3:
The number 248 fits into 718 2 times, leaving a remainder of 222.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 496 from 718, we get 222.
Include the next digit (6) from the dividend after 222, then repeat: 2226 / 248

Going ahead to step 4:
248 goes into 2226 8 times with a remainder of 242.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we subtract 1984 from 2226, we get 242.
Grab the next digit (4) from the dividend, add it to 242, then carry on: 2424 / 248

On to step 5:
2424 divided by 248 is 9 with a remainder of 192.
The next digit of our result is 9. 
Result so far: 289.0
If we subtract 2232 from 2424, we get 192.
Fetch the next digit (8) from the dividend, attach it to 192 and continue: 1928 / 248

Advancing to step 6:
The number 248 fits into 1928 7 times, leaving a remainder of 192.
The next digit of our result is 7. 
Result so far: 2897.0
Subtracting 1736 from 1928 leaves us with 192.
Include the next digit (3) from the dividend after 192, then repeat: 1923 / 248

On to step 7:
If we divide 1923 by 248, we get 7 and a remainder of 187.
Write down 7 as next digit of the result. 
Result so far: 28977.0
If we take 1736 away from 1923, we end up with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 8:
248 can be fit into 1870 7 times, resulting in a remainder of 134.
The number 7 becomes the next digit in our result. 
Result so far: 28977.7
Deduct 1736 from 1870 and we're left with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 9:
248 can be fit into 1340 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 28977.75
If we take 1240 away from 1340, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 10:
When dividing 1000 by 248, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 28977.754
The remainder is 8 after subtracting 992 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
248 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 28977.754
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
800 divided by 248 is 3 with a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 28977.75403
The remainder is 56 after subtracting 744 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
If we divide 560 by 248, we get 2 and a remainder of 64.
The next digit of our result is 2. 
Result so far: 28977.754032
Deduct 496 from 560 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
248 goes into 640 2 times with a remainder of 144.
The number 2 becomes the next digit in our result. 
Result so far: 28977.7540322
Deduct 496 from 640 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

After the division, we end up with 28977.7540322 and a remainder of 1.44e-06.
