57818784 divided by 20 
We're looking to find how many times 20 goes into 57818784.

On to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 20

Let's proceed to step 2:
20 can be fit into 57 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 40 from 57 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 20

Moving on to step 3:
The number 20 fits into 178 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 18 after subtracting 160 from 178.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 20

Going ahead to step 4:
When dividing 181 by 20, we get 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
The remainder is 1 after subtracting 180 from 181.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 20

Step 5:
If we divide 18 by 20, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 2890.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (7) from the dividend and append it to 18, then repeat: 187 / 20

Moving on to step 6:
The number 20 fits into 187 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 28909.0
Subtract 180 from 187 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 20

Advancing to step 7:
20 goes into 78 3 times with a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 289093.0
If we take 60 away from 78, we end up with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 20

On to step 8:
When dividing 184 by 20, we get 9 with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 2890939.0
If we subtract 180 from 184, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2890939.2
Subtracting 40 from 40 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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2890939.2
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.

Moving on to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2890939.2
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 outcome is 2890939.2, with a leftover of 0.0.
