783498 ÷ 12 
The aim is to understand the frequency of 12 in 783498.

On to step 1:
12 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 12

Moving on to step 2:
78 divided by 12 is 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 72 away from 78, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 12

Moving on to step 3:
12 goes into 63 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 60 away from 63, we end up with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 12

On to step 4:
34 divided by 12 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 652.0
Deduct 24 from 34 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 12

On to step 5:
If we divide 109 by 12, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 6529.0
If we subtract 108 from 109, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

Going ahead to step 6:
If we divide 18 by 12, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 65291.0
If we take 12 away from 18, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 65291.5
Deduct 60 from 60 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 65291.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 65291.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 65291.5 with a remaining 0.0.
