We're dividing 50640160 by 486 
We want to figure out the number of times 50640160 can be divided by 486.

Let's proceed to step 1:
The number 486 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 486

Step 2:
If we divide 50 by 486, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 486

Step 3:
486 can be fit into 506 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 486 from 506, we get 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 486

Going ahead to step 4:
486 can be fit into 204 0 times, resulting in a remainder of 204.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 204 after subtracting 0 from 204.
Grab the next digit (0) from the dividend, add it to 204, then carry on: 2040 / 486

Advancing to step 5:
When dividing 2040 by 486, we get 4 with a remainder of 96.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtract 1944 from 2040 to get 96.
Take the next digit (1) from the dividend and append it to 96, then repeat: 961 / 486

Moving on to step 6:
The number 486 fits into 961 1 times, leaving a remainder of 475.
Write down 1 as next digit of the result. 
Result so far: 1041.0
If we take 486 away from 961, we end up with 475.
Fetch the next digit (6) from the dividend, attach it to 475 and continue: 4756 / 486

Let's proceed to step 7:
486 can be fit into 4756 9 times, resulting in a remainder of 382.
The number 9 becomes the next digit in our result. 
Result so far: 10419.0
If we subtract 4374 from 4756, we get 382.
Grab the next digit (0) from the dividend, add it to 382, then carry on: 3820 / 486

Moving on to step 8:
The number 486 fits into 3820 7 times, leaving a remainder of 418.
The next digit of our result is 7. 
Result so far: 104197.0
The remainder is 418 after subtracting 3402 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 9:
486 can be fit into 4180 8 times, resulting in a remainder of 292.
Put 8 as the next digit of the answer. 
Result so far: 104197.8
If we take 3888 away from 4180, we end up with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 10:
When dividing 2920 by 486, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 104197.86
If we subtract 2916 from 2920, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
40 divided by 486 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 104197.86
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
When dividing 400 by 486, we get 0 with a remainder of 400.
The next digit of our result is 0. 
Result so far: 104197.86
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

In conclusion, the division gives 104197.86 with a balance of 0.004.
