51159854 ÷ 493 
We want to divide 51159854 by 493.

Going ahead to step 1:
When dividing 5 by 493, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 493

Going ahead to step 2:
If we divide 51 by 493, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 493

Step 3:
When dividing 511 by 493, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 493 from 511 leaves us with 18.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 493

Step 4:
185 divided by 493 is 0 with a remainder of 185.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 185, we end up with 185.
Fetch the next digit (9) from the dividend, attach it to 185 and continue: 1859 / 493

Advancing to step 5:
493 can be fit into 1859 3 times, resulting in a remainder of 380.
Use 3 as the next digit of our solution. 
Result so far: 103.0
If we subtract 1479 from 1859, we get 380.
Bring next digit (8) of the dividend behind the 380 and repeat the process: 3808 / 493

On to step 6:
3808 divided by 493 is 7 with a remainder of 357.
Put 7 as the next digit of the answer. 
Result so far: 1037.0
Subtract 3451 from 3808 to get 357.
Include the next digit (5) from the dividend after 357, then repeat: 3575 / 493

On to step 7:
If we divide 3575 by 493, we get 7 and a remainder of 124.
The next digit of our result is 7. 
Result so far: 10377.0
The remainder is 124 after subtracting 3451 from 3575.
Grab the next digit (4) from the dividend, add it to 124, then carry on: 1244 / 493

Advancing to step 8:
When dividing 1244 by 493, we get 2 with a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 103772.0
If we subtract 986 from 1244, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 9:
When dividing 2580 by 493, we get 5 with a remainder of 115.
The number 5 becomes the next digit in our result. 
Result so far: 103772.5
Subtract 2465 from 2580 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 10:
493 goes into 1150 2 times with a remainder of 164.
The next digit of our result is 2. 
Result so far: 103772.52
If we subtract 986 from 1150, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 11:
If we divide 1640 by 493, we get 3 and a remainder of 161.
Use 3 as the next digit of our solution. 
Result so far: 103772.523
Subtract 1479 from 1640 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

On to step 12:
493 can be fit into 1610 3 times, resulting in a remainder of 131.
Put 3 as the next digit of the answer. 
Result so far: 103772.5233
Subtract 1479 from 1610 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The quotient of the division is 103772.5233, and the remainder is 0.00131.
