We look at the division of 2439354 by 620 
We want to divide 2439354 by 620.

Step 1:
620 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 620

Step 2:
If we divide 24 by 620, we get 0 and a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Bring next digit (3) of the dividend behind the 24 and repeat the process: 243 / 620

Moving on to step 3:
620 goes into 243 0 times with a remainder of 243.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 243, we end up with 243.
Grab the next digit (9) from the dividend, add it to 243, then carry on: 2439 / 620

On to step 4:
620 can be fit into 2439 3 times, resulting in a remainder of 579.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1860 away from 2439, we end up with 579.
Bring next digit (3) of the dividend behind the 579 and repeat the process: 5793 / 620

Let's proceed to step 5:
If we divide 5793 by 620, we get 9 and a remainder of 213.
The next digit of our result is 9. 
Result so far: 39.0
Subtracting 5580 from 5793 leaves us with 213.
Fetch the next digit (5) from the dividend, attach it to 213 and continue: 2135 / 620

On to step 6:
2135 divided by 620 is 3 with a remainder of 275.
Use 3 as the next digit of our solution. 
Result so far: 393.0
If we subtract 1860 from 2135, we get 275.
Bring next digit (4) of the dividend behind the 275 and repeat the process: 2754 / 620

Going ahead to step 7:
The number 620 fits into 2754 4 times, leaving a remainder of 274.
Record the quotient 4 as the next digit in the result. 
Result so far: 3934.0
Subtract 2480 from 2754 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 8:
If we divide 2740 by 620, we get 4 and a remainder of 260.
Put 4 as the next digit of the answer. 
Result so far: 3934.4
Subtracting 2480 from 2740 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 9:
2600 divided by 620 is 4 with a remainder of 120.
The number 4 becomes the next digit in our result. 
Result so far: 3934.44
The remainder is 120 after subtracting 2480 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

The final outcome is 3934.44, with a leftover of 0.12.
