We look at the division of 2707105 by 621 
Let's see how many times 621 fits into 2707105.

Advancing to step 1:
The number 621 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 621

Step 2:
27 divided by 621 is 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (0) from the dividend, add it to 27, then carry on: 270 / 621

Going ahead to step 3:
The number 621 fits into 270 0 times, leaving a remainder of 270.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 270 after subtracting 0 from 270.
Append the next digit (7) from the dividend to 270 and continue with: 2707 / 621

Moving on to step 4:
When dividing 2707 by 621, we get 4 with a remainder of 223.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 2484 from 2707 and we're left with 223.
Grab the next digit (1) from the dividend, add it to 223, then carry on: 2231 / 621

Step 5:
621 goes into 2231 3 times with a remainder of 368.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
If we subtract 1863 from 2231, we get 368.
Append the next digit (0) from the dividend to 368 and continue with: 3680 / 621

Going ahead to step 6:
If we divide 3680 by 621, we get 5 and a remainder of 575.
The next digit of our result is 5. 
Result so far: 435.0
Deduct 3105 from 3680 and we're left with 575.
Grab the next digit (5) from the dividend, add it to 575, then carry on: 5755 / 621

Moving on to step 7:
621 can be fit into 5755 9 times, resulting in a remainder of 166.
The number 9 becomes the next digit in our result. 
Result so far: 4359.0
Subtract 5589 from 5755 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 8:
The number 621 fits into 1660 2 times, leaving a remainder of 418.
The next digit of our result is 2. 
Result so far: 4359.2
Subtracting 1242 from 1660 leaves us with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Going ahead to step 9:
When dividing 4180 by 621, we get 6 with a remainder of 454.
Write down 6 as next digit of the result. 
Result so far: 4359.26
Subtract 3726 from 4180 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 10:
4540 divided by 621 is 7 with a remainder of 193.
The number 7 becomes the next digit in our result. 
Result so far: 4359.267
Subtract 4347 from 4540 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 11:
If we divide 1930 by 621, we get 3 and a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 4359.2673
If we take 1863 away from 1930, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
When dividing 670 by 621, we get 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 4359.26731
Subtract 621 from 670 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 13:
When dividing 490 by 621, we get 0 with a remainder of 490.
The number 0 becomes the next digit in our result. 
Result so far: 4359.26731
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

On to step 14:
When dividing 4900 by 621, we get 7 with a remainder of 553.
Use 7 as the next digit of our solution. 
Result so far: 4359.2673107
If we subtract 4347 from 4900, we get 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Moving on to step 15:
When dividing 5530 by 621, we get 8 with a remainder of 562.
Use 8 as the next digit of our solution. 
Result so far: 4359.26731078
If we subtract 4968 from 5530, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Our division results in 4359.26731078 with a remaining 5.62e-07.
