We divide 20155320 by 513
We want to figure out the number of times 20155320 can be divided by 513.

Let's proceed to step 1:
When dividing 2 by 513, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 513

Advancing to step 2:
20 divided by 513 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 513

Moving on to step 3:
The number 513 fits into 201 0 times, leaving a remainder of 201.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 201 leaves us with 201.
Append the next digit (5) from the dividend to 201 and continue with: 2015 / 513

Moving on to step 4:
The number 513 fits into 2015 3 times, leaving a remainder of 476.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1539 from 2015, we get 476.
Take the next digit (5) from the dividend and append it to 476, then repeat: 4765 / 513

Step 5:
513 can be fit into 4765 9 times, resulting in a remainder of 148.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 4617 from 4765 to get 148.
Take the next digit (3) from the dividend and append it to 148, then repeat: 1483 / 513

Going ahead to step 6:
513 can be fit into 1483 2 times, resulting in a remainder of 457.
Put 2 as the next digit of the answer. 
Result so far: 392.0
Subtracting 1026 from 1483 leaves us with 457.
Fetch the next digit (2) from the dividend, attach it to 457 and continue: 4572 / 513

Advancing to step 7:
When dividing 4572 by 513, we get 8 with a remainder of 468.
Put 8 as the next digit of the answer. 
Result so far: 3928.0
If we subtract 4104 from 4572, we get 468.
Include the next digit (0) from the dividend after 468, then repeat: 4680 / 513

On to step 8:
513 goes into 4680 9 times with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 39289.0
Subtracting 4617 from 4680 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
513 goes into 630 1 times with a remainder of 117.
The next digit of our result is 1. 
Result so far: 39289.1
Subtract 513 from 630 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 10:
When dividing 1170 by 513, we get 2 with a remainder of 144.
Record the quotient 2 as the next digit in the result. 
Result so far: 39289.12
Subtracting 1026 from 1170 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
When dividing 1440 by 513, we get 2 with a remainder of 414.
Use 2 as the next digit of our solution. 
Result so far: 39289.122
If we take 1026 away from 1440, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

After the division, we end up with 39289.122 and a remainder of 0.0414.
