28005421 ÷ 746 
The aim is to understand the frequency of 746 in 28005421.

On to step 1:
If we divide 2 by 746, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 746

Going ahead to step 2:
The number 746 fits into 28 0 times, leaving a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 746

Moving on to step 3:
When dividing 280 by 746, we get 0 with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 280, we end up with 280.
Bring next digit (0) of the dividend behind the 280 and repeat the process: 2800 / 746

Let's proceed to step 4:
If we divide 2800 by 746, we get 3 and a remainder of 562.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2238 from 2800 leaves us with 562.
Include the next digit (5) from the dividend after 562, then repeat: 5625 / 746

Going ahead to step 5:
5625 divided by 746 is 7 with a remainder of 403.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 403 after subtracting 5222 from 5625.
Fetch the next digit (4) from the dividend, attach it to 403 and continue: 4034 / 746

Let's proceed to step 6:
When dividing 4034 by 746, we get 5 with a remainder of 304.
The number 5 becomes the next digit in our result. 
Result so far: 375.0
Subtracting 3730 from 4034 leaves us with 304.
Bring next digit (2) of the dividend behind the 304 and repeat the process: 3042 / 746

On to step 7:
The number 746 fits into 3042 4 times, leaving a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 3754.0
If we take 2984 away from 3042, we end up with 58.
Take the next digit (1) from the dividend and append it to 58, then repeat: 581 / 746

On to step 8:
581 divided by 746 is 0 with a remainder of 581.
Use 0 as the next digit of our solution. 
Result so far: 37540.0
Subtracting 0 from 581 leaves us with 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Moving on to step 9:
The number 746 fits into 5810 7 times, leaving a remainder of 588.
Use 7 as the next digit of our solution. 
Result so far: 37540.7
Deduct 5222 from 5810 and we're left with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 10:
746 goes into 5880 7 times with a remainder of 658.
The number 7 becomes the next digit in our result. 
Result so far: 37540.77
If we take 5222 away from 5880, we end up with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

The final outcome is 37540.77, with a leftover of 0.658.
