51356539 ÷ 493 
We're looking to find how many times 493 goes into 51356539.

Let's proceed to step 1:
493 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 493

On to step 2:
493 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (3) of the dividend behind the 51 and repeat the process: 513 / 493

Advancing to step 3:
493 can be fit into 513 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 493 from 513 and we're left with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 493

Let's proceed to step 4:
493 can be fit into 205 0 times, resulting in a remainder of 205.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 205 after subtracting 0 from 205.
Append the next digit (6) from the dividend to 205 and continue with: 2056 / 493

Step 5:
2056 divided by 493 is 4 with a remainder of 84.
Write down 4 as next digit of the result. 
Result so far: 104.0
Deduct 1972 from 2056 and we're left with 84.
Include the next digit (5) from the dividend after 84, then repeat: 845 / 493

On to step 6:
When dividing 845 by 493, we get 1 with a remainder of 352.
Use 1 as the next digit of our solution. 
Result so far: 1041.0
Deduct 493 from 845 and we're left with 352.
Include the next digit (3) from the dividend after 352, then repeat: 3523 / 493

Advancing to step 7:
If we divide 3523 by 493, we get 7 and a remainder of 72.
Put 7 as the next digit of the answer. 
Result so far: 10417.0
Subtract 3451 from 3523 to get 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 493

Step 8:
493 goes into 729 1 times with a remainder of 236.
Use 1 as the next digit of our solution. 
Result so far: 104171.0
If we take 493 away from 729, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 9:
2360 divided by 493 is 4 with a remainder of 388.
Write down 4 as next digit of the result. 
Result so far: 104171.4
Subtract 1972 from 2360 to get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 10:
The number 493 fits into 3880 7 times, leaving a remainder of 429.
Use 7 as the next digit of our solution. 
Result so far: 104171.47
If we subtract 3451 from 3880, we get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 11:
If we divide 4290 by 493, we get 8 and a remainder of 346.
Record the quotient 8 as the next digit in the result. 
Result so far: 104171.478
Subtracting 3944 from 4290 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Step 12:
If we divide 3460 by 493, we get 7 and a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 104171.4787
If we subtract 3451 from 3460, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
The number 493 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 104171.4787
Subtract 0 from 90 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 14:
493 goes into 900 1 times with a remainder of 407.
The next digit of our result is 1. 
Result so far: 104171.478701
The remainder is 407 after subtracting 493 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 15:
If we divide 4070 by 493, we get 8 and a remainder of 126.
Put 8 as the next digit of the answer. 
Result so far: 104171.4787018
Deduct 3944 from 4070 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 16:
493 can be fit into 1260 2 times, resulting in a remainder of 274.
The next digit of our result is 2. 
Result so far: 104171.47870182
Subtract 986 from 1260 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

The final result is 104171.47870182 with a remainder of 2.74e-07.
