We divide 389090 by 38
We want to figure out the number of times 389090 can be divided by 38.

On to step 1:
If we divide 3 by 38, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 38

Advancing to step 2:
If we divide 38 by 38, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 38 away from 38, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 38

Advancing to step 3:
The number 38 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 38

On to step 4:
When dividing 90 by 38, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 102.0
Subtract 76 from 90 to get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 38

Advancing to step 5:
The number 38 fits into 149 3 times, leaving a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 1023.0
Subtract 114 from 149 to get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 38

Going ahead to step 6:
When dividing 350 by 38, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 10239.0
Subtract 342 from 350 to 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.

On to step 7:
When dividing 80 by 38, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 10239.2
If we subtract 76 from 80, we get 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 8:
38 goes into 40 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 10239.21
Deduct 38 from 40 and we're left 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.

Let's proceed to step 9:
If we divide 20 by 38, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10239.21
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.

On to step 10:
38 goes into 200 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10239.2105
Subtracting 190 from 200 leaves us 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.

On to step 11:
100 divided by 38 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 10239.21052
If we take 76 away from 100, we end up 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.

Going ahead to step 12:
38 goes into 240 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 10239.210526
Subtracting 228 from 240 leaves us with 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 13:
38 can be fit into 120 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 10239.2105263
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
38 can be fit into 60 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 10239.21052631
Subtract 38 from 60 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 10239.21052631 with a remainder of 2.2e-08.
