We're dividing 67484570 by 20 
We want to figure out the number of times 67484570 can be divided by 20.

Advancing to step 1:
20 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 20

Step 2:
20 goes into 67 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 7 after subtracting 60 from 67.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 20

Step 3:
If we divide 74 by 20, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtract 60 from 74 to get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 20

Let's proceed to step 4:
20 can be fit into 148 7 times, resulting in a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 337.0
Deduct 140 from 148 and we're left with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 20

Step 5:
84 divided by 20 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 3374.0
If we take 80 away from 84, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 20

Going ahead to step 6:
20 can be fit into 45 2 times, resulting in a remainder of 5.
The next digit of our result is 2. 
Result so far: 33742.0
If we take 40 away from 45, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 20

Step 7:
20 can be fit into 57 2 times, resulting in a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 337422.0
Subtract 40 from 57 to get 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 20

Moving on to step 8:
When dividing 170 by 20, we get 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 3374228.0
If we subtract 160 from 170, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3374228.5
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.

On to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3374228.5
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.

Moving 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: 3374228.5
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 final outcome is 3374228.5, with a leftover of 0.0.
