We look at the division of 51212584 by 950 
We want to divide 51212584 by 950.

On to step 1:
When dividing 5 by 950, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 950

Let's proceed to step 2:
950 can be fit into 51 0 times, resulting in a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 950

Going ahead to step 3:
512 divided by 950 is 0 with a remainder of 512.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 512 and we're left with 512.
Take the next digit (1) from the dividend and append it to 512, then repeat: 5121 / 950

Let's proceed to step 4:
The number 950 fits into 5121 5 times, leaving a remainder of 371.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 4750 from 5121 leaves us with 371.
Include the next digit (2) from the dividend after 371, then repeat: 3712 / 950

Going ahead to step 5:
950 can be fit into 3712 3 times, resulting in a remainder of 862.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 862 after subtracting 2850 from 3712.
Grab the next digit (5) from the dividend, add it to 862, then carry on: 8625 / 950

On to step 6:
The number 950 fits into 8625 9 times, leaving a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 539.0
Subtract 8550 from 8625 to get 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 950

Advancing to step 7:
758 divided by 950 is 0 with a remainder of 758.
Write down 0 as next digit of the result. 
Result so far: 5390.0
Subtract 0 from 758 to get 758.
Bring next digit (4) of the dividend behind the 758 and repeat the process: 7584 / 950

Moving on to step 8:
7584 divided by 950 is 7 with a remainder of 934.
Record the quotient 7 as the next digit in the result. 
Result so far: 53907.0
Subtract 6650 from 7584 to get 934.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9340, and continue the process.

Going ahead to step 9:
If we divide 9340 by 950, we get 9 and a remainder of 790.
Use 9 as the next digit of our solution. 
Result so far: 53907.9
If we take 8550 away from 9340, we end up with 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 10:
950 goes into 7900 8 times with a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 53907.98
The remainder is 300 after subtracting 7600 from 7900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
When dividing 3000 by 950, we get 3 with a remainder of 150.
Record the quotient 3 as the next digit in the result. 
Result so far: 53907.983
Subtracting 2850 from 3000 leaves us with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
The number 950 fits into 1500 1 times, leaving a remainder of 550.
Put 1 as the next digit of the answer. 
Result so far: 53907.9831
If we subtract 950 from 1500, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Step 13:
The number 950 fits into 5500 5 times, leaving a remainder of 750.
Use 5 as the next digit of our solution. 
Result so far: 53907.98315
The remainder is 750 after subtracting 4750 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 14:
950 goes into 7500 7 times with a remainder of 850.
The next digit of our result is 7. 
Result so far: 53907.983157
The remainder is 850 after subtracting 6650 from 7500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Step 15:
950 can be fit into 8500 8 times, resulting in a remainder of 900.
The number 8 becomes the next digit in our result. 
Result so far: 53907.9831578
Subtract 7600 from 8500 to get 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9000, and continue the process.

Advancing to step 16:
950 goes into 9000 9 times with a remainder of 450.
Put 9 as the next digit of the answer. 
Result so far: 53907.98315789
If we take 8550 away from 9000, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 53907.98315789 and a remainder of 4.5e-07.
