27034504 ÷ 621 
We want to divide 27034504 by 621.

Let's proceed to step 1:
621 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 621

On to step 2:
621 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 621

Moving on to step 3:
621 can be fit into 270 0 times, resulting in a remainder of 270.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 270 after subtracting 0 from 270.
Include the next digit (3) from the dividend after 270, then repeat: 2703 / 621

Going ahead to step 4:
If we divide 2703 by 621, we get 4 and a remainder of 219.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2484 from 2703, we get 219.
Grab the next digit (4) from the dividend, add it to 219, then carry on: 2194 / 621

Advancing to step 5:
When dividing 2194 by 621, we get 3 with a remainder of 331.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 1863 from 2194 to get 331.
Append the next digit (5) from the dividend to 331 and continue with: 3315 / 621

Step 6:
3315 divided by 621 is 5 with a remainder of 210.
Record the quotient 5 as the next digit in the result. 
Result so far: 435.0
Subtracting 3105 from 3315 leaves us with 210.
Grab the next digit (0) from the dividend, add it to 210, then carry on: 2100 / 621

Moving on to step 7:
2100 divided by 621 is 3 with a remainder of 237.
Put 3 as the next digit of the answer. 
Result so far: 4353.0
If we subtract 1863 from 2100, we get 237.
Take the next digit (4) from the dividend and append it to 237, then repeat: 2374 / 621

Let's proceed to step 8:
The number 621 fits into 2374 3 times, leaving a remainder of 511.
Use 3 as the next digit of our solution. 
Result so far: 43533.0
If we subtract 1863 from 2374, we get 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Step 9:
621 goes into 5110 8 times with a remainder of 142.
Write down 8 as next digit of the result. 
Result so far: 43533.8
If we take 4968 away from 5110, we end up with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
If we divide 1420 by 621, we get 2 and a remainder of 178.
Put 2 as the next digit of the answer. 
Result so far: 43533.82
Subtracting 1242 from 1420 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Let's proceed to step 11:
The number 621 fits into 1780 2 times, leaving a remainder of 538.
Use 2 as the next digit of our solution. 
Result so far: 43533.822
The remainder is 538 after subtracting 1242 from 1780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The final outcome is 43533.822, with a leftover of 0.0538.
