Let's divide 51405937 by 489
Our goal is to divide 51405937 by 489.

Advancing to step 1:
When dividing 5 by 489, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 489

Advancing to step 2:
489 can be fit into 51 0 times, resulting in a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 489

Advancing to step 3:
The number 489 fits into 514 1 times, leaving a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 489 from 514 leaves us with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 489

On to step 4:
250 divided by 489 is 0 with a remainder of 250.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 250 leaves us with 250.
Grab the next digit (5) from the dividend, add it to 250, then carry on: 2505 / 489

Moving on to step 5:
When dividing 2505 by 489, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 105.0
The remainder is 60 after subtracting 2445 from 2505.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 489

Moving on to step 6:
489 can be fit into 609 1 times, resulting in a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 1051.0
Subtracting 489 from 609 leaves us with 120.
Grab the next digit (3) from the dividend, add it to 120, then carry on: 1203 / 489

Advancing to step 7:
489 goes into 1203 2 times with a remainder of 225.
Put 2 as the next digit of the answer. 
Result so far: 10512.0
If we subtract 978 from 1203, we get 225.
Include the next digit (7) from the dividend after 225, then repeat: 2257 / 489

Moving on to step 8:
The number 489 fits into 2257 4 times, leaving a remainder of 301.
Use 4 as the next digit of our solution. 
Result so far: 105124.0
Subtracting 1956 from 2257 leaves us with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 9:
When dividing 3010 by 489, we get 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 105124.6
Subtract 2934 from 3010 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
When dividing 760 by 489, we get 1 with a remainder of 271.
Put 1 as the next digit of the answer. 
Result so far: 105124.61
If we subtract 489 from 760, we get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Moving on to step 11:
The number 489 fits into 2710 5 times, leaving a remainder of 265.
The next digit of our result is 5. 
Result so far: 105124.615
Deduct 2445 from 2710 and we're left with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 12:
When dividing 2650 by 489, we get 5 with a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 105124.6155
The remainder is 205 after subtracting 2445 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 105124.6155 and a remainder of 0.00205.
