We're dividing 621404 by 38 
Let's see how many times 38 fits into 621404.

On to step 1:
The number 38 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 38

Advancing to step 2:
If we divide 62 by 38, we get 1 and a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 38 away from 62, we end up with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 38

Step 3:
38 can be fit into 241 6 times, resulting in a remainder of 13.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 13 after subtracting 228 from 241.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 38

Going ahead to step 4:
The number 38 fits into 134 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 163.0
Deduct 114 from 134 and we're left with 20.
Grab the next digit (0) from the dividend, add it to 20, then carry on: 200 / 38

Going ahead to step 5:
38 can be fit into 200 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 1635.0
If we take 190 away from 200, we end up with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 38

Let's proceed to step 6:
When dividing 104 by 38, we get 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 16352.0
If we take 76 away from 104, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
The number 38 fits into 280 7 times, leaving a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 16352.7
The remainder is 14 after subtracting 266 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
When dividing 140 by 38, we get 3 with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 16352.73
The remainder is 26 after subtracting 114 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
38 goes into 260 6 times with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 16352.736
If we take 228 away from 260, 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.

Advancing to step 10:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 16352.7368
Subtracting 304 from 320 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 38 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 16352.73684
If we subtract 152 from 160, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
38 goes into 80 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 16352.736842
Deduct 76 from 80 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
38 can be fit into 40 1 times, resulting in a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 16352.7368421
If we subtract 38 from 40, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
38 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 16352.7368421
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 16352.7368421, with a leftover of 2e-08.
