Step 2:
39 divided by 620 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (7) from the dividend to 39 and continue with: 397 / 620

Let's proceed to step 3:
620 can be fit into 397 0 times, resulting in a remainder of 397.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 397 to get 397.
Append the next digit (3) from the dividend to 397 and continue with: 3973 / 620

On to step 4:
3973 divided by 620 is 6 with a remainder of 253.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 3720 from 3973 leaves us with 253.
Grab the next digit (4) from the dividend, add it to 253, then carry on: 2534 / 620

On to step 5:
2534 divided by 620 is 4 with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Subtracting 2480 from 2534 leaves us with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 620

Advancing to step 6:
549 divided by 620 is 0 with a remainder of 549.
Record the quotient 0 as the next digit in the result. 
Result so far: 640.0
Subtract 0 from 549 to get 549.
Bring next digit (2) of the dividend behind the 549 and repeat the process: 5492 / 620

On to step 7:
5492 divided by 620 is 8 with a remainder of 532.
Write down 8 as next digit of the result. 
Result so far: 6408.0
If we subtract 4960 from 5492, we get 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Moving on to step 8:
The number 620 fits into 5320 8 times, leaving a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 6408.8
Deduct 4960 from 5320 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 9:
620 goes into 3600 5 times with a remainder of 500.
Use 5 as the next digit of our solution. 
Result so far: 6408.85
Subtract 3100 from 3600 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 10:
620 can be fit into 5000 8 times, resulting in a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 6408.858
Deduct 4960 from 5000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 620, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 6408.858
Subtract 0 from 400 to get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 12:
If we divide 4000 by 620, we get 6 and a remainder of 280.
Use 6 as the next digit of our solution. 
Result so far: 6408.85806
The remainder is 280 after subtracting 3720 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
620 goes into 2800 4 times with a remainder of 320.
Put 4 as the next digit of the answer. 
Result so far: 6408.858064
If we subtract 2480 from 2800, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 14:
620 can be fit into 3200 5 times, resulting in a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 6408.8580645
Deduct 3100 from 3200 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
620 goes into 1000 1 times with a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 6408.85806451
Subtract 620 from 1000 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The quotient of the division is 6408.85806451, and the remainder is 3.8e-07.
