We divide 50493678 by 621
We want to figure out the number of times 50493678 can be divided by 621.

On to step 1:
When dividing 5 by 621, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 621

Going ahead to step 2:
621 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 621

Going ahead to step 3:
If we divide 504 by 621, we get 0 and a remainder of 504.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 504 to get 504.
Bring next digit (9) of the dividend behind the 504 and repeat the process: 5049 / 621

On to step 4:
If we divide 5049 by 621, we get 8 and a remainder of 81.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 4968 from 5049 and we're left with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 621

Advancing to step 5:
621 goes into 813 1 times with a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 81.0
The remainder is 192 after subtracting 621 from 813.
Include the next digit (6) from the dividend after 192, then repeat: 1926 / 621

Going ahead to step 6:
The number 621 fits into 1926 3 times, leaving a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 813.0
If we subtract 1863 from 1926, we get 63.
Take the next digit (7) from the dividend and append it to 63, then repeat: 637 / 621

Let's proceed to step 7:
If we divide 637 by 621, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 8131.0
If we take 621 away from 637, we end up with 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 621

Moving on to step 8:
If we divide 168 by 621, we get 0 and a remainder of 168.
Put 0 as the next digit of the answer. 
Result so far: 81310.0
Subtracting 0 from 168 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 9:
1680 divided by 621 is 2 with a remainder of 438.
The number 2 becomes the next digit in our result. 
Result so far: 81310.2
If we subtract 1242 from 1680, we get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Let's proceed to step 10:
If we divide 4380 by 621, we get 7 and a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 81310.27
The remainder is 33 after subtracting 4347 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 11:
621 can be fit into 330 0 times, resulting in a remainder of 330.
Put 0 as the next digit of the answer. 
Result so far: 81310.27
Deduct 0 from 330 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Moving on to step 12:
When dividing 3300 by 621, we get 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 81310.2705
Subtract 3105 from 3300 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 13:
1950 divided by 621 is 3 with a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 81310.27053
Deduct 1863 from 1950 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 14:
870 divided by 621 is 1 with a remainder of 249.
Write down 1 as next digit of the result. 
Result so far: 81310.270531
If we subtract 621 from 870, we get 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 15:
621 can be fit into 2490 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 81310.2705314
If we subtract 2484 from 2490, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 16:
When dividing 60 by 621, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 81310.2705314
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 81310.2705314 with a remainder of 6e-08.
