We look at the division of 1860639 by 812 
The aim is to understand the frequency of 812 in 1860639.

Step 1:
If we divide 1 by 812, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 812

Going ahead to step 2:
The number 812 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 812

Let's proceed to step 3:
If we divide 186 by 812, we get 0 and a remainder of 186.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 186 after subtracting 0 from 186.
Take the next digit (0) from the dividend and append it to 186, then repeat: 1860 / 812

On to step 4:
The number 812 fits into 1860 2 times, leaving a remainder of 236.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 1624 from 1860 to get 236.
Append the next digit (6) from the dividend to 236 and continue with: 2366 / 812

Let's proceed to step 5:
812 can be fit into 2366 2 times, resulting in a remainder of 742.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Subtract 1624 from 2366 to get 742.
Take the next digit (3) from the dividend and append it to 742, then repeat: 7423 / 812

Advancing to step 6:
7423 divided by 812 is 9 with a remainder of 115.
Use 9 as the next digit of our solution. 
Result so far: 229.0
The remainder is 115 after subtracting 7308 from 7423.
Append the next digit (9) from the dividend to 115 and continue with: 1159 / 812

Advancing to step 7:
1159 divided by 812 is 1 with a remainder of 347.
Write down 1 as next digit of the result. 
Result so far: 2291.0
If we subtract 812 from 1159, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 8:
When dividing 3470 by 812, we get 4 with a remainder of 222.
Put 4 as the next digit of the answer. 
Result so far: 2291.4
The remainder is 222 after subtracting 3248 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 9:
When dividing 2220 by 812, we get 2 with a remainder of 596.
The next digit of our result is 2. 
Result so far: 2291.42
If we take 1624 away from 2220, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 10:
If we divide 5960 by 812, we get 7 and a remainder of 276.
Put 7 as the next digit of the answer. 
Result so far: 2291.427
Subtracting 5684 from 5960 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 11:
812 can be fit into 2760 3 times, resulting in a remainder of 324.
Use 3 as the next digit of our solution. 
Result so far: 2291.4273
If we take 2436 away from 2760, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 12:
If we divide 3240 by 812, we get 3 and a remainder of 804.
The next digit of our result is 3. 
Result so far: 2291.42733
The remainder is 804 after subtracting 2436 from 3240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8040, and continue the process.

Our division results in 2291.42733 with a remaining 0.000804.
