61681 ÷ 4 
The aim is to understand the frequency of 4 in 61681.

Moving on to step 1:
When dividing 6 by 4, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 4 from 6 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Advancing to step 2:
When dividing 21 by 4, we get 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 1 after subtracting 20 from 21.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 4

Let's proceed to step 3:
16 divided by 4 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we subtract 16 from 16, we get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 4

Moving on to step 4:
4 goes into 8 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 1542.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

Let's proceed to step 5:
When dividing 1 by 4, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 15420.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
The number 4 fits into 10 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 15420.2
If we subtract 8 from 10, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15420.25
Subtract 20 from 20 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15420.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15420.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15420.25, and the remainder is 0.0.
