Let's divide 57315149 by 20
We want to divide 57315149 by 20.

On to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 20

Let's proceed to step 2:
The number 20 fits into 57 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 40 from 57, we get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 20

Advancing to step 3:
The number 20 fits into 173 8 times, leaving a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 13 after subtracting 160 from 173.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 20

Going ahead to step 4:
131 divided by 20 is 6 with a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 286.0
Subtracting 120 from 131 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 20

Going ahead to step 5:
When dividing 115 by 20, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 2865.0
Subtracting 100 from 115 leaves us with 15.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 20

Let's proceed to step 6:
20 goes into 151 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 28657.0
If we take 140 away from 151, we end up with 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 20

Advancing to step 7:
The number 20 fits into 114 5 times, leaving a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 286575.0
The remainder is 14 after subtracting 100 from 114.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 20

On to step 8:
149 divided by 20 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 2865757.0
If we subtract 140 from 149, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
If we divide 90 by 20, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 2865757.4
Subtract 80 from 90 to 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.

Step 10:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2865757.45
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.

Let's proceed to step 11:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2865757.45
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 12:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2865757.45
If we subtract 0 from 0, 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.

After the division, we end up with 2865757.45 and a remainder of 0.0.
