Let's divide 16873146 by 213
The aim is to understand the frequency of 213 in 16873146.

Moving on to step 1:
If we divide 1 by 213, we get 0 and 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 (6) from the dividend, add it to 1, then carry on: 16 / 213

Advancing to step 2:
When dividing 16 by 213, we get 0 with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 213

Going ahead to step 3:
The number 213 fits into 168 0 times, leaving a remainder of 168.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 168 after subtracting 0 from 168.
Fetch the next digit (7) from the dividend, attach it to 168 and continue: 1687 / 213

On to step 4:
213 can be fit into 1687 7 times, resulting in a remainder of 196.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 1491 away from 1687, we end up with 196.
Fetch the next digit (3) from the dividend, attach it to 196 and continue: 1963 / 213

Step 5:
213 can be fit into 1963 9 times, resulting in a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 46 after subtracting 1917 from 1963.
Include the next digit (1) from the dividend after 46, then repeat: 461 / 213

Moving on to step 6:
461 divided by 213 is 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 792.0
Subtract 426 from 461 to get 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 213

Step 7:
When dividing 354 by 213, we get 1 with a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 7921.0
If we subtract 213 from 354, we get 141.
Fetch the next digit (6) from the dividend, attach it to 141 and continue: 1416 / 213

Advancing to step 8:
213 can be fit into 1416 6 times, resulting in a remainder of 138.
The number 6 becomes the next digit in our result. 
Result so far: 79216.0
The remainder is 138 after subtracting 1278 from 1416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 9:
The number 213 fits into 1380 6 times, leaving a remainder of 102.
Use 6 as the next digit of our solution. 
Result so far: 79216.6
Subtract 1278 from 1380 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

On to step 10:
When dividing 1020 by 213, we get 4 with a remainder of 168.
Record the quotient 4 as the next digit in the result. 
Result so far: 79216.64
Subtracting 852 from 1020 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 11:
The number 213 fits into 1680 7 times, leaving a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 79216.647
Deduct 1491 from 1680 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 12:
If we divide 1890 by 213, we get 8 and a remainder of 186.
Record the quotient 8 as the next digit in the result. 
Result so far: 79216.6478
The remainder is 186 after subtracting 1704 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 13:
If we divide 1860 by 213, we get 8 and a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 79216.64788
If we take 1704 away from 1860, we end up with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Our division results in 79216.64788 with a remaining 0.000156.
