Let's divide 33312998 by 213
The aim is to understand the frequency of 213 in 33312998.

On to step 1:
213 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 213

On to step 2:
33 divided by 213 is 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 213

Let's proceed to step 3:
If we divide 333 by 213, we get 1 and a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 213 away from 333, we end up with 120.
Take the next digit (1) from the dividend and append it to 120, then repeat: 1201 / 213

Moving on to step 4:
When dividing 1201 by 213, we get 5 with a remainder of 136.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 1065 from 1201 leaves us with 136.
Fetch the next digit (2) from the dividend, attach it to 136 and continue: 1362 / 213

Moving on to step 5:
213 goes into 1362 6 times with a remainder of 84.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtract 1278 from 1362 to get 84.
Bring next digit (9) of the dividend behind the 84 and repeat the process: 849 / 213

On to step 6:
When dividing 849 by 213, we get 3 with a remainder of 210.
The number 3 becomes the next digit in our result. 
Result so far: 1563.0
If we take 639 away from 849, we end up with 210.
Fetch the next digit (9) from the dividend, attach it to 210 and continue: 2109 / 213

Moving on to step 7:
213 goes into 2109 9 times with a remainder of 192.
The number 9 becomes the next digit in our result. 
Result so far: 15639.0
If we take 1917 away from 2109, we end up with 192.
Grab the next digit (8) from the dividend, add it to 192, then carry on: 1928 / 213

On to step 8:
If we divide 1928 by 213, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 156399.0
Deduct 1917 from 1928 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
If we divide 110 by 213, we get 0 and a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 156399.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
213 can be fit into 1100 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 156399.05
If we subtract 1065 from 1100, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
213 goes into 350 1 times with a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 156399.051
Subtracting 213 from 350 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 12:
If we divide 1370 by 213, we get 6 and a remainder of 92.
Record the quotient 6 as the next digit in the result. 
Result so far: 156399.0516
Subtracting 1278 from 1370 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 13:
920 divided by 213 is 4 with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 156399.05164
Subtract 852 from 920 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
213 can be fit into 680 3 times, resulting in a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 156399.051643
Deduct 639 from 680 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
213 goes into 410 1 times with a remainder of 197.
Record the quotient 1 as the next digit in the result. 
Result so far: 156399.0516431
Subtracting 213 from 410 leaves us with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

On to step 16:
If we divide 1970 by 213, we get 9 and a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 156399.05164319
Deduct 1917 from 1970 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The final outcome is 156399.05164319, with a leftover of 5.3e-08.
