203171 ÷ 39 
Let's see how many times 39 fits into 203171.

Step 1:
2 divided by 39 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 39

On to step 2:
The number 39 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 39

Step 3:
When dividing 203 by 39, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 8 after subtracting 195 from 203.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 39

Let's proceed to step 4:
81 divided by 39 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 78 away from 81, we end up with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 39

On to step 5:
If we divide 37 by 39, we get 0 and a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 520.0
If we take 0 away from 37, we end up with 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 39

Let's proceed to step 6:
39 goes into 371 9 times with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 5209.0
Deduct 351 from 371 and we're left 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.

Going ahead to step 7:
200 divided by 39 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 5209.5
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 39 fits into 50 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 5209.51
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
39 can be fit into 110 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 5209.512
Subtract 78 from 110 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.

Going ahead to step 10:
39 goes into 320 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 5209.5128
Subtracting 312 from 320 leaves us 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.

On to step 11:
When dividing 80 by 39, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 5209.51282
If we subtract 78 from 80, 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 12:
When dividing 20 by 39, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5209.51282
Subtract 0 from 20 to 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.

Advancing to step 13:
200 divided by 39 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 5209.5128205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
50 divided by 39 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 5209.51282051
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 5209.51282051, with a leftover of 1.1e-08.
