We're dividing 50213147 by 621 
Our goal is to divide 50213147 by 621.

Moving on to step 1:
5 divided by 621 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 621

Let's proceed to step 2:
50 divided by 621 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Grab the next digit (2) from the dividend, add it to 50, then carry on: 502 / 621

Going ahead to step 3:
The number 621 fits into 502 0 times, leaving a remainder of 502.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 502, we get 502.
Fetch the next digit (1) from the dividend, attach it to 502 and continue: 5021 / 621

Advancing to step 4:
5021 divided by 621 is 8 with a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 4968 away from 5021, we end up with 53.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 621

Moving on to step 5:
If we divide 533 by 621, we get 0 and a remainder of 533.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we subtract 0 from 533, we get 533.
Fetch the next digit (1) from the dividend, attach it to 533 and continue: 5331 / 621

Moving on to step 6:
If we divide 5331 by 621, we get 8 and a remainder of 363.
Use 8 as the next digit of our solution. 
Result so far: 808.0
If we subtract 4968 from 5331, we get 363.
Include the next digit (4) from the dividend after 363, then repeat: 3634 / 621

Let's proceed to step 7:
621 goes into 3634 5 times with a remainder of 529.
Record the quotient 5 as the next digit in the result. 
Result so far: 8085.0
If we take 3105 away from 3634, we end up with 529.
Fetch the next digit (7) from the dividend, attach it to 529 and continue: 5297 / 621

Going ahead to step 8:
When dividing 5297 by 621, we get 8 with a remainder of 329.
The number 8 becomes the next digit in our result. 
Result so far: 80858.0
Subtract 4968 from 5297 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 9:
621 can be fit into 3290 5 times, resulting in a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 80858.5
Subtract 3105 from 3290 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 10:
When dividing 1850 by 621, we get 2 with a remainder of 608.
Use 2 as the next digit of our solution. 
Result so far: 80858.52
The remainder is 608 after subtracting 1242 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 11:
6080 divided by 621 is 9 with a remainder of 491.
Put 9 as the next digit of the answer. 
Result so far: 80858.529
The remainder is 491 after subtracting 5589 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Moving on to step 12:
When dividing 4910 by 621, we get 7 with a remainder of 563.
The next digit of our result is 7. 
Result so far: 80858.5297
Subtract 4347 from 4910 to get 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Step 13:
621 goes into 5630 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 80858.52979
Deduct 5589 from 5630 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 14:
410 divided by 621 is 0 with a remainder of 410.
Put 0 as the next digit of the answer. 
Result so far: 80858.52979
If we take 0 away from 410, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 15:
621 can be fit into 4100 6 times, resulting in a remainder of 374.
The next digit of our result is 6. 
Result so far: 80858.5297906
Subtract 3726 from 4100 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 16:
The number 621 fits into 3740 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 80858.52979066
The remainder is 14 after subtracting 3726 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 80858.52979066 with a remainder of 1.4e-08.
