We look at the division of 10620379 by 388 
Let's see how many times 388 fits into 10620379.

On to step 1:
The number 388 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 388

Going ahead to step 2:
388 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 388

Advancing to step 3:
388 can be fit into 106 0 times, resulting in a remainder of 106.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 106, we end up with 106.
Fetch the next digit (2) from the dividend, attach it to 106 and continue: 1062 / 388

On to step 4:
1062 divided by 388 is 2 with a remainder of 286.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 776 from 1062 and we're left with 286.
Take the next digit (0) from the dividend and append it to 286, then repeat: 2860 / 388

Step 5:
The number 388 fits into 2860 7 times, leaving a remainder of 144.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 2716 from 2860, we get 144.
Take the next digit (3) from the dividend and append it to 144, then repeat: 1443 / 388

On to step 6:
388 goes into 1443 3 times with a remainder of 279.
Use 3 as the next digit of our solution. 
Result so far: 273.0
If we take 1164 away from 1443, we end up with 279.
Fetch the next digit (7) from the dividend, attach it to 279 and continue: 2797 / 388

On to step 7:
388 can be fit into 2797 7 times, resulting in a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 2737.0
Deduct 2716 from 2797 and we're left with 81.
Take the next digit (9) from the dividend and append it to 81, then repeat: 819 / 388

Step 8:
If we divide 819 by 388, we get 2 and a remainder of 43.
Record the quotient 2 as the next digit in the result. 
Result so far: 27372.0
Subtracting 776 from 819 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
If we divide 430 by 388, we get 1 and a remainder of 42.
The next digit of our result is 1. 
Result so far: 27372.1
The remainder is 42 after subtracting 388 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
If we divide 420 by 388, we get 1 and a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 27372.11
If we take 388 away from 420, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 27372.11, and the remainder is 0.032.
