We divide 50849069 by 621
Let's see how many times 621 fits into 50849069.

Step 1:
If we divide 5 by 621, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 621

Going ahead to step 2:
The number 621 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 621

Going ahead to step 3:
621 goes into 508 0 times with a remainder of 508.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 508 and we're left with 508.
Grab the next digit (4) from the dividend, add it to 508, then carry on: 5084 / 621

Step 4:
621 can be fit into 5084 8 times, resulting in a remainder of 116.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 4968 away from 5084, we end up with 116.
Bring next digit (9) of the dividend behind the 116 and repeat the process: 1169 / 621

Advancing to step 5:
621 goes into 1169 1 times with a remainder of 548.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 548 after subtracting 621 from 1169.
Include the next digit (0) from the dividend after 548, then repeat: 5480 / 621

Going ahead to step 6:
The number 621 fits into 5480 8 times, leaving a remainder of 512.
Put 8 as the next digit of the answer. 
Result so far: 818.0
If we subtract 4968 from 5480, we get 512.
Grab the next digit (6) from the dividend, add it to 512, then carry on: 5126 / 621

Moving on to step 7:
621 can be fit into 5126 8 times, resulting in a remainder of 158.
Put 8 as the next digit of the answer. 
Result so far: 8188.0
If we subtract 4968 from 5126, we get 158.
Take the next digit (9) from the dividend and append it to 158, then repeat: 1589 / 621

Let's proceed to step 8:
621 can be fit into 1589 2 times, resulting in a remainder of 347.
Use 2 as the next digit of our solution. 
Result so far: 81882.0
Subtract 1242 from 1589 to get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 9:
The number 621 fits into 3470 5 times, leaving a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 81882.5
Subtracting 3105 from 3470 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Advancing to step 10:
The number 621 fits into 3650 5 times, leaving a remainder of 545.
Use 5 as the next digit of our solution. 
Result so far: 81882.55
Deduct 3105 from 3650 and we're left with 545.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

The final result is 81882.55 with a remainder of 0.545.
