6551 ÷ 4 
The aim is to understand the frequency of 4 in 6551.

Moving on to step 1:
The number 4 fits into 6 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 4 from 6 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 4

Going ahead to step 2:
The number 4 fits into 25 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 24 from 25 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

Going ahead to step 3:
If we divide 15 by 4, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 163.0
If we take 12 away from 15, we end up with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 4

On to step 4:
When dividing 31 by 4, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 1637.0
The remainder is 3 after subtracting 28 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 5:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 1637.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
20 divided by 4 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1637.75
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.

Step 7:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1637.75
If we take 0 away from 0, we end up 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.

Advancing to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1637.75
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.

Our division results in 1637.75 with a remaining 0.0.
