105278 divided by 18 
The aim is to understand the frequency of 18 in 105278.

Going ahead to step 1:
The number 18 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 18

On to step 2:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 18

Moving on to step 3:
The number 18 fits into 105 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 90 from 105 to get 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 18

Moving on to step 4:
If we divide 152 by 18, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 144 from 152 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 18

Moving on to step 5:
When dividing 87 by 18, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 584.0
If we subtract 72 from 87, we get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 18

On to step 6:
18 goes into 158 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 5848.0
Subtracting 144 from 158 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 18 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 5848.7
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
When dividing 140 by 18, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 5848.77
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 5848.77 and a remainder of 0.014.
