Let's divide 643430 by 38
Let's see how many times 38 fits into 643430.

Let's proceed to step 1:
6 divided by 38 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 38

Moving on to step 2:
38 goes into 64 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 38 from 64 and we're left with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 38

On to step 3:
38 can be fit into 263 6 times, resulting in a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 228 from 263 leaves us with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 38

Moving on to step 4:
When dividing 354 by 38, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 169.0
Deduct 342 from 354 and we're left with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 38

Step 5:
When dividing 123 by 38, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 1693.0
If we take 114 away from 123, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 38

On to step 6:
The number 38 fits into 90 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 16932.0
If we take 76 away from 90, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
When dividing 140 by 38, we get 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 16932.3
Deduct 114 from 140 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
38 can be fit into 260 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 16932.36
Subtract 228 from 260 to get 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 9:
When dividing 320 by 38, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 16932.368
If we subtract 304 from 320, we get 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 10:
38 can be fit into 160 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 16932.3684
If we take 152 away from 160, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
38 can be fit into 80 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 16932.36842
If we take 76 away from 80, we end up 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.

On to step 12:
The number 38 fits into 40 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 16932.368421
If we take 38 away from 40, we end up with 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 13:
When dividing 20 by 38, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 16932.368421
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
When dividing 200 by 38, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 16932.36842105
Deduct 190 from 200 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 16932.36842105, with a leftover of 1e-08.
