153433 ÷ 20 
The aim is to understand the frequency of 20 in 153433.

Advancing to step 1:
1 divided by 20 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 20

Let's proceed to step 2:
The number 20 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 20

Step 3:
If we divide 153 by 20, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 140 from 153, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 20

Going ahead to step 4:
134 divided by 20 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 14 after subtracting 120 from 134.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 20

Let's proceed to step 5:
20 goes into 143 7 times with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 767.0
Deduct 140 from 143 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 20

Step 6:
The number 20 fits into 33 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 7671.0
If we subtract 20 from 33, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 20 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 7671.6
Subtracting 120 from 130 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7671.65
Deduct 100 from 100 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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7671.65
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7671.65
Subtract 0 from 0 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.

After the division, we end up with 7671.65 and a remainder of 0.0.
