52321031 ÷ 513 
Our goal is to divide 52321031 by 513.

On to step 1:
When dividing 5 by 513, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 513

On to step 2:
When dividing 52 by 513, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (3) from the dividend, attach it to 52 and continue: 523 / 513

Moving on to step 3:
When dividing 523 by 513, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 513 from 523, we get 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 513

Going ahead to step 4:
The number 513 fits into 102 0 times, leaving a remainder of 102.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 102, we end up with 102.
Take the next digit (1) from the dividend and append it to 102, then repeat: 1021 / 513

Let's proceed to step 5:
1021 divided by 513 is 1 with a remainder of 508.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 513 from 1021, we get 508.
Append the next digit (0) from the dividend to 508 and continue with: 5080 / 513

Let's proceed to step 6:
The number 513 fits into 5080 9 times, leaving a remainder of 463.
Use 9 as the next digit of our solution. 
Result so far: 1019.0
Subtract 4617 from 5080 to get 463.
Grab the next digit (3) from the dividend, add it to 463, then carry on: 4633 / 513

On to step 7:
4633 divided by 513 is 9 with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 10199.0
Subtracting 4617 from 4633 leaves us with 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 513

Moving on to step 8:
513 can be fit into 161 0 times, resulting in a remainder of 161.
The next digit of our result is 0. 
Result so far: 101990.0
If we take 0 away from 161, we end up with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 9:
When dividing 1610 by 513, we get 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 101990.3
If we take 1539 away from 1610, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
If we divide 710 by 513, we get 1 and a remainder of 197.
The next digit of our result is 1. 
Result so far: 101990.31
Deduct 513 from 710 and we're left with 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 11:
513 can be fit into 1970 3 times, resulting in a remainder of 431.
The number 3 becomes the next digit in our result. 
Result so far: 101990.313
If we subtract 1539 from 1970, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Step 12:
The number 513 fits into 4310 8 times, leaving a remainder of 206.
Write down 8 as next digit of the result. 
Result so far: 101990.3138
Subtracting 4104 from 4310 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 13:
2060 divided by 513 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 101990.31384
Deduct 2052 from 2060 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
The number 513 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 101990.31384
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 15:
If we divide 800 by 513, we get 1 and a remainder of 287.
Record the quotient 1 as the next digit in the result. 
Result so far: 101990.3138401
Deduct 513 from 800 and we're left with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Advancing to step 16:
The number 513 fits into 2870 5 times, leaving a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 101990.31384015
Subtract 2565 from 2870 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

The final result is 101990.31384015 with a remainder of 3.05e-07.
