9744012 ÷ 213 
The aim is to understand the frequency of 213 in 9744012.

Advancing to step 1:
When dividing 9 by 213, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 213

Advancing to step 2:
When dividing 97 by 213, we get 0 with a remainder of 97.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Bring next digit (4) of the dividend behind the 97 and repeat the process: 974 / 213

Step 3:
213 can be fit into 974 4 times, resulting in a remainder of 122.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 852 from 974 to get 122.
Take the next digit (4) from the dividend and append it to 122, then repeat: 1224 / 213

Going ahead to step 4:
1224 divided by 213 is 5 with a remainder of 159.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
If we subtract 1065 from 1224, we get 159.
Take the next digit (0) from the dividend and append it to 159, then repeat: 1590 / 213

Advancing to step 5:
When dividing 1590 by 213, we get 7 with a remainder of 99.
The next digit of our result is 7. 
Result so far: 457.0
The remainder is 99 after subtracting 1491 from 1590.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 213

Moving on to step 6:
213 goes into 991 4 times with a remainder of 139.
Use 4 as the next digit of our solution. 
Result so far: 4574.0
If we subtract 852 from 991, we get 139.
Take the next digit (2) from the dividend and append it to 139, then repeat: 1392 / 213

Going ahead to step 7:
When dividing 1392 by 213, we get 6 with a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 45746.0
Subtracting 1278 from 1392 leaves us with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 8:
213 goes into 1140 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 45746.5
If we subtract 1065 from 1140, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
750 divided by 213 is 3 with a remainder of 111.
Write down 3 as next digit of the result. 
Result so far: 45746.53
Subtract 639 from 750 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

On to step 10:
The number 213 fits into 1110 5 times, leaving a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 45746.535
Subtract 1065 from 1110 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 11:
If we divide 450 by 213, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 45746.5352
If we take 426 away from 450, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
213 goes into 240 1 times with a remainder of 27.
The next digit of our result is 1. 
Result so far: 45746.53521
Subtract 213 from 240 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
213 can be fit into 270 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 45746.535211
The remainder is 57 after subtracting 213 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 45746.535211 and a remainder of 5.7e-06.
