We look at the division of 19782637 by 486 
Our goal is to divide 19782637 by 486.

Going ahead to step 1:
The number 486 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 486

Moving on to step 2:
19 divided by 486 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 486

Going ahead to step 3:
486 can be fit into 197 0 times, resulting in a remainder of 197.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 197, we get 197.
Append the next digit (8) from the dividend to 197 and continue with: 1978 / 486

Step 4:
486 can be fit into 1978 4 times, resulting in a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1944 away from 1978, we end up with 34.
Bring next digit (2) of the dividend behind the 34 and repeat the process: 342 / 486

Step 5:
486 goes into 342 0 times with a remainder of 342.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 342 to get 342.
Grab the next digit (6) from the dividend, add it to 342, then carry on: 3426 / 486

Advancing to step 6:
When dividing 3426 by 486, we get 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 407.0
Subtracting 3402 from 3426 leaves us with 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 486

Step 7:
243 divided by 486 is 0 with a remainder of 243.
Use 0 as the next digit of our solution. 
Result so far: 4070.0
If we take 0 away from 243, we end up with 243.
Bring next digit (7) of the dividend behind the 243 and repeat the process: 2437 / 486

Advancing to step 8:
If we divide 2437 by 486, we get 5 and a remainder of 7.
The next digit of our result is 5. 
Result so far: 40705.0
If we subtract 2430 from 2437, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
When dividing 70 by 486, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 40705.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
700 divided by 486 is 1 with a remainder of 214.
Put 1 as the next digit of the answer. 
Result so far: 40705.01
Deduct 486 from 700 and we're left with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 11:
The number 486 fits into 2140 4 times, leaving a remainder of 196.
Record the quotient 4 as the next digit in the result. 
Result so far: 40705.014
The remainder is 196 after subtracting 1944 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Let's proceed to step 12:
When dividing 1960 by 486, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 40705.0144
If we subtract 1944 from 1960, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 40705.0144 with a remaining 0.00016.
