We divide 209172 by 39
We want to figure out the number of times 209172 can be divided by 39.

On to step 1:
If we divide 2 by 39, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 39

Moving on to step 2:
39 can be fit into 20 0 times, resulting in 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.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 39

Let's proceed 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.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 39

Moving on to step 4:
If we divide 141 by 39, we get 3 and a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 24 after subtracting 117 from 141.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 39

Moving on to step 5:
39 goes into 247 6 times with a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 536.0
Subtract 234 from 247 to get 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 39

Step 6:
39 can be fit into 132 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 5363.0
If we take 117 away from 132, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 5363.3
If we take 117 away from 150, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
When dividing 330 by 39, we get 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 5363.38
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 5363.384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
If we divide 240 by 39, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 5363.3846
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
39 can be fit into 60 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 5363.38461
Subtracting 39 from 60 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
The number 39 fits into 210 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 5363.384615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
If we divide 150 by 39, we get 3 and a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 5363.3846153
If we subtract 117 from 150, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 14:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 5363.38461538
Deduct 312 from 330 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 5363.38461538 and a remainder of 1.8e-08.
