745901 ÷ 84 
The aim is to understand the frequency of 84 in 745901.

Let's proceed to step 1:
When dividing 7 by 84, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 84

Going ahead to step 2:
The number 84 fits into 74 0 times, leaving a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Include the next digit (5) from the dividend after 74, then repeat: 745 / 84

Let's proceed to step 3:
84 goes into 745 8 times with a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 672 from 745 leaves us with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 84

Going ahead to step 4:
84 goes into 739 8 times with a remainder of 67.
The next digit of our result is 8. 
Result so far: 88.0
The remainder is 67 after subtracting 672 from 739.
Bring next digit (0) of the dividend behind the 67 and repeat the process: 670 / 84

Step 5:
84 goes into 670 7 times with a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 887.0
The remainder is 82 after subtracting 588 from 670.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 84

On to step 6:
84 can be fit into 821 9 times, resulting in a remainder of 65.
The next digit of our result is 9. 
Result so far: 8879.0
Subtract 756 from 821 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 7:
If we divide 650 by 84, we get 7 and a remainder of 62.
Put 7 as the next digit of the answer. 
Result so far: 8879.7
Deduct 588 from 650 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
When dividing 620 by 84, we get 7 with a remainder of 32.
The next digit of our result is 7. 
Result so far: 8879.77
Subtract 588 from 620 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 8879.77, and the remainder is 0.032.
