51357205 divided by 506 
We want to figure out the number of times 51357205 can be divided by 506.

On to step 1:
506 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 506

Step 2:
506 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 506

Let's proceed to step 3:
506 can be fit into 513 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 506 from 513 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 506

Advancing to step 4:
506 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 75, we get 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 506

On to step 5:
757 divided by 506 is 1 with a remainder of 251.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
The remainder is 251 after subtracting 506 from 757.
Take the next digit (2) from the dividend and append it to 251, then repeat: 2512 / 506

Let's proceed to step 6:
2512 divided by 506 is 4 with a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 1014.0
If we take 2024 away from 2512, we end up with 488.
Include the next digit (0) from the dividend after 488, then repeat: 4880 / 506

Let's proceed to step 7:
4880 divided by 506 is 9 with a remainder of 326.
The number 9 becomes the next digit in our result. 
Result so far: 10149.0
If we subtract 4554 from 4880, we get 326.
Bring next digit (5) of the dividend behind the 326 and repeat the process: 3265 / 506

On to step 8:
3265 divided by 506 is 6 with a remainder of 229.
Write down 6 as next digit of the result. 
Result so far: 101496.0
The remainder is 229 after subtracting 3036 from 3265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 9:
2290 divided by 506 is 4 with a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 101496.4
Deduct 2024 from 2290 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Advancing to step 10:
When dividing 2660 by 506, we get 5 with a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 101496.45
The remainder is 130 after subtracting 2530 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
506 can be fit into 1300 2 times, resulting in a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 101496.452
Subtract 1012 from 1300 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 12:
The number 506 fits into 2880 5 times, leaving a remainder of 350.
Write down 5 as next digit of the result. 
Result so far: 101496.4525
Deduct 2530 from 2880 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
506 goes into 3500 6 times with a remainder of 464.
Put 6 as the next digit of the answer. 
Result so far: 101496.45256
If we take 3036 away from 3500, we end up with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 14:
506 goes into 4640 9 times with a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 101496.452569
The remainder is 86 after subtracting 4554 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 15:
When dividing 860 by 506, we get 1 with a remainder of 354.
The next digit of our result is 1. 
Result so far: 101496.4525691
Subtract 506 from 860 to get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Going ahead to step 16:
The number 506 fits into 3540 6 times, leaving a remainder of 504.
The next digit of our result is 6. 
Result so far: 101496.45256916
Deduct 3036 from 3540 and we're left with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Our division results in 101496.45256916 with a remaining 5.04e-07.
