We look at the division of 621405 by 38 
We're looking to find how many times 38 goes into 621405.

Advancing to step 1:
If we divide 6 by 38, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 38

Moving on to step 2:
38 goes into 62 1 times with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 38 from 62 and we're left with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 38

Let's proceed to step 3:
If we divide 241 by 38, we get 6 and a remainder of 13.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 228 from 241 and we're left with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 38

Moving on to step 4:
134 divided by 38 is 3 with a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 163.0
The remainder is 20 after subtracting 114 from 134.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 38

Advancing to step 5:
38 can be fit into 200 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1635.0
If we take 190 away from 200, we end up with 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 38

Going ahead to step 6:
38 can be fit into 105 2 times, resulting in a remainder of 29.
Put 2 as the next digit of the answer. 
Result so far: 16352.0
The remainder is 29 after subtracting 76 from 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
38 goes into 290 7 times with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 16352.7
Deduct 266 from 290 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
If we divide 240 by 38, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 16352.76
If we subtract 228 from 240, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
120 divided by 38 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 16352.763
If we take 114 away from 120, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 38 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 16352.7631
Subtracting 38 from 60 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
38 goes into 220 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 16352.76315
The remainder is 30 after subtracting 190 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
If we divide 300 by 38, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 16352.763157
The remainder is 34 after subtracting 266 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 13:
When dividing 340 by 38, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 16352.7631578
If we subtract 304 from 340, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
360 divided by 38 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 16352.76315789
Deduct 342 from 360 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 16352.76315789 with a remaining 1.8e-08.
