67384451 divided by 20 
We're looking to find how many times 20 goes into 67384451.

Going ahead to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 20

On to step 2:
67 divided by 20 is 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 7 after subtracting 60 from 67.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 20

On to step 3:
20 goes into 73 3 times with a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we subtract 60 from 73, we get 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 20

Advancing to step 4:
When dividing 138 by 20, we get 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 336.0
If we take 120 away from 138, we end up with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 20

Step 5:
If we divide 184 by 20, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 3369.0
If we take 180 away from 184, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 20

Moving on to step 6:
20 can be fit into 44 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 33692.0
If we take 40 away from 44, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Let's proceed to step 7:
When dividing 45 by 20, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 336922.0
Subtract 40 from 45 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 20

Moving on to step 8:
If we divide 51 by 20, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 3369222.0
If we take 40 away from 51, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
When dividing 110 by 20, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3369222.5
Deduct 100 from 110 and we're left 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.

Going ahead to step 10:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3369222.55
Subtracting 100 from 100 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 outcome is 3369222.55, with a leftover of 0.0.
