We're dividing 74215436 by 213 
The aim is to understand the frequency of 213 in 74215436.

Moving on to step 1:
213 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 213

On to step 2:
213 goes into 74 0 times with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Include the next digit (2) from the dividend after 74, then repeat: 742 / 213

On to step 3:
When dividing 742 by 213, we get 3 with a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 639 from 742 and we're left with 103.
Grab the next digit (1) from the dividend, add it to 103, then carry on: 1031 / 213

On to step 4:
1031 divided by 213 is 4 with a remainder of 179.
The next digit of our result is 4. 
Result so far: 34.0
The remainder is 179 after subtracting 852 from 1031.
Include the next digit (5) from the dividend after 179, then repeat: 1795 / 213

On to step 5:
If we divide 1795 by 213, we get 8 and a remainder of 91.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
If we subtract 1704 from 1795, we get 91.
Fetch the next digit (4) from the dividend, attach it to 91 and continue: 914 / 213

Going ahead to step 6:
213 goes into 914 4 times with a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 3484.0
If we take 852 away from 914, we end up with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 213

Step 7:
623 divided by 213 is 2 with a remainder of 197.
Record the quotient 2 as the next digit in the result. 
Result so far: 34842.0
Subtract 426 from 623 to get 197.
Include the next digit (6) from the dividend after 197, then repeat: 1976 / 213

Advancing to step 8:
When dividing 1976 by 213, we get 9 with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 348429.0
If we subtract 1917 from 1976, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
213 goes into 590 2 times with a remainder of 164.
The next digit of our result is 2. 
Result so far: 348429.2
Subtracting 426 from 590 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 10:
The number 213 fits into 1640 7 times, leaving a remainder of 149.
Write down 7 as next digit of the result. 
Result so far: 348429.27
If we take 1491 away from 1640, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 11:
If we divide 1490 by 213, we get 6 and a remainder of 212.
Record the quotient 6 as the next digit in the result. 
Result so far: 348429.276
If we subtract 1278 from 1490, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 12:
213 goes into 2120 9 times with a remainder of 203.
Record the quotient 9 as the next digit in the result. 
Result so far: 348429.2769
Subtract 1917 from 2120 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 13:
The number 213 fits into 2030 9 times, leaving a remainder of 113.
Record the quotient 9 as the next digit in the result. 
Result so far: 348429.27699
Deduct 1917 from 2030 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

After the division, we end up with 348429.27699 and a remainder of 0.000113.
