209972 divided by 39 
We want to figure out the number of times 209972 can be divided by 39.

Moving on to step 1:
2 divided by 39 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 39

Going ahead to step 2:
The number 39 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 39

On to step 3:
39 can be fit into 209 5 times, resulting in a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 195 away from 209, we end up with 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 39

Going ahead to step 4:
39 goes into 149 3 times with a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Deduct 117 from 149 and we're left with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 39

Going ahead to step 5:
If we divide 327 by 39, we get 8 and a remainder of 15.
The next digit of our result is 8. 
Result so far: 538.0
If we take 312 away from 327, we end up with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 39

Let's proceed to step 6:
152 divided by 39 is 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 5383.0
If we subtract 117 from 152, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
If we divide 350 by 39, we get 8 and a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 5383.8
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
39 goes into 380 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 5383.89
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
39 goes into 290 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 5383.897
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
39 goes into 170 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 5383.8974
The remainder is 14 after subtracting 156 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 5383.89743
Deduct 117 from 140 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 12:
When dividing 230 by 39, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 5383.897435
The remainder is 35 after subtracting 195 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 13:
350 divided by 39 is 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 5383.8974358
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 14:
39 can be fit into 380 9 times, resulting in a remainder of 29.
The next digit of our result is 9. 
Result so far: 5383.89743589
If we subtract 351 from 380, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 5383.89743589, with a leftover of 2.9e-08.
