Let's divide 18197870 by 812
The aim is to understand the frequency of 812 in 18197870.

Let's proceed to step 1:
812 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 812

Going ahead to step 2:
If we divide 18 by 812, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 812

On to step 3:
181 divided by 812 is 0 with a remainder of 181.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 181 leaves us with 181.
Bring next digit (9) of the dividend behind the 181 and repeat the process: 1819 / 812

Moving on to step 4:
The number 812 fits into 1819 2 times, leaving a remainder of 195.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1624 from 1819, we get 195.
Bring next digit (7) of the dividend behind the 195 and repeat the process: 1957 / 812

Step 5:
812 goes into 1957 2 times with a remainder of 333.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 1624 from 1957 to get 333.
Fetch the next digit (8) from the dividend, attach it to 333 and continue: 3338 / 812

Let's proceed to step 6:
812 goes into 3338 4 times with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 224.0
Subtract 3248 from 3338 to get 90.
Include the next digit (7) from the dividend after 90, then repeat: 907 / 812

Moving on to step 7:
The number 812 fits into 907 1 times, leaving a remainder of 95.
The next digit of our result is 1. 
Result so far: 2241.0
Subtracting 812 from 907 leaves us with 95.
Fetch the next digit (0) from the dividend, attach it to 95 and continue: 950 / 812

Moving on to step 8:
812 goes into 950 1 times with a remainder of 138.
Record the quotient 1 as the next digit in the result. 
Result so far: 22411.0
Deduct 812 from 950 and we're left with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
812 can be fit into 1380 1 times, resulting in a remainder of 568.
Use 1 as the next digit of our solution. 
Result so far: 22411.1
If we take 812 away from 1380, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Advancing to step 10:
If we divide 5680 by 812, we get 6 and a remainder of 808.
The next digit of our result is 6. 
Result so far: 22411.16
Deduct 4872 from 5680 and we're left with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

Going ahead to step 11:
When dividing 8080 by 812, we get 9 with a remainder of 772.
Put 9 as the next digit of the answer. 
Result so far: 22411.169
If we subtract 7308 from 8080, we get 772.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7720, and continue the process.

Going ahead to step 12:
812 goes into 7720 9 times with a remainder of 412.
The next digit of our result is 9. 
Result so far: 22411.1699
Subtract 7308 from 7720 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Our division results in 22411.1699 with a remaining 0.00412.
