Let's divide 75304355 by 20
We're looking to find how many times 20 goes into 75304355.

Let's proceed to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 20

Let's proceed to step 2:
If we divide 75 by 20, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 60 from 75 and we're left with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 20

On to step 3:
20 can be fit into 153 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 140 from 153 to get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 20

Advancing to step 4:
The number 20 fits into 130 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 376.0
If we take 120 away from 130, we end up with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 20

On to step 5:
When dividing 104 by 20, we get 5 with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 3765.0
Subtract 100 from 104 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 20

Step 6:
The number 20 fits into 43 2 times, leaving a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 37652.0
The remainder is 3 after subtracting 40 from 43.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Moving on to step 7:
20 goes into 35 1 times with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 376521.0
Subtract 20 from 35 to get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 20

Let's proceed to step 8:
20 goes into 155 7 times with a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 3765217.0
Deduct 140 from 155 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
20 goes into 150 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 3765217.7
Subtracting 140 from 150 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.

Step 10:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3765217.75
If we subtract 100 from 100, 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.

On to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3765217.75
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.

Advancing to step 12:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3765217.75
Subtracting 0 from 0 leaves us 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 final result is 3765217.75 with a remainder of 0.0.
