We look at the division of 278599 by 620 
We want to divide 278599 by 620.

Step 1:
When dividing 2 by 620, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 620

Advancing to step 2:
620 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 620

Let's proceed to step 3:
If we divide 278 by 620, we get 0 and a remainder of 278.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 278, we end up with 278.
Include the next digit (5) from the dividend after 278, then repeat: 2785 / 620

Going ahead to step 4:
When dividing 2785 by 620, we get 4 with a remainder of 305.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 2480 away from 2785, we end up with 305.
Bring next digit (9) of the dividend behind the 305 and repeat the process: 3059 / 620

Step 5:
620 goes into 3059 4 times with a remainder of 579.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
Subtract 2480 from 3059 to get 579.
Fetch the next digit (9) from the dividend, attach it to 579 and continue: 5799 / 620

Going ahead to step 6:
When dividing 5799 by 620, we get 9 with a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 449.0
Deduct 5580 from 5799 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 7:
620 goes into 2190 3 times with a remainder of 330.
The next digit of our result is 3. 
Result so far: 449.3
Subtracting 1860 from 2190 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 8:
When dividing 3300 by 620, we get 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 449.35
The remainder is 200 after subtracting 3100 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 9:
If we divide 2000 by 620, we get 3 and a remainder of 140.
Use 3 as the next digit of our solution. 
Result so far: 449.353
Deduct 1860 from 2000 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 10:
1400 divided by 620 is 2 with a remainder of 160.
Put 2 as the next digit of the answer. 
Result so far: 449.3532
Subtract 1240 from 1400 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
1600 divided by 620 is 2 with a remainder of 360.
The number 2 becomes the next digit in our result. 
Result so far: 449.35322
If we subtract 1240 from 1600, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The final result is 449.35322 with a remainder of 0.00036.
