Let's divide 3619780 by 621
We're looking to find how many times 621 goes into 3619780.

Going ahead to step 1:
When dividing 3 by 621, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 621

Going ahead to step 2:
If we divide 36 by 621, we get 0 and a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 621

Advancing to step 3:
361 divided by 621 is 0 with a remainder of 361.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 361 and we're left with 361.
Grab the next digit (9) from the dividend, add it to 361, then carry on: 3619 / 621

Moving on to step 4:
When dividing 3619 by 621, we get 5 with a remainder of 514.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 3105 from 3619 to get 514.
Include the next digit (7) from the dividend after 514, then repeat: 5147 / 621

Going ahead to step 5:
5147 divided by 621 is 8 with a remainder of 179.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we take 4968 away from 5147, we end up with 179.
Fetch the next digit (8) from the dividend, attach it to 179 and continue: 1798 / 621

Going ahead to step 6:
621 goes into 1798 2 times with a remainder of 556.
Write down 2 as next digit of the result. 
Result so far: 582.0
Deduct 1242 from 1798 and we're left with 556.
Include the next digit (0) from the dividend after 556, then repeat: 5560 / 621

On to step 7:
621 goes into 5560 8 times with a remainder of 592.
The number 8 becomes the next digit in our result. 
Result so far: 5828.0
If we subtract 4968 from 5560, we get 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Let's proceed to step 8:
5920 divided by 621 is 9 with a remainder of 331.
Put 9 as the next digit of the answer. 
Result so far: 5828.9
Deduct 5589 from 5920 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Advancing to step 9:
When dividing 3310 by 621, we get 5 with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 5828.95
Subtract 3105 from 3310 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 10:
If we divide 2050 by 621, we get 3 and a remainder of 187.
The next digit of our result is 3. 
Result so far: 5828.953
Deduct 1863 from 2050 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Step 11:
The number 621 fits into 1870 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 5828.9533
Deduct 1863 from 1870 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 5828.9533 with a remainder of 7e-05.
