642348 ÷ 39 
Our goal is to divide 642348 by 39.

Moving on to step 1:
39 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 39

On to step 2:
When dividing 64 by 39, we get 1 with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 39 from 64 leaves us with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 39

On to step 3:
The number 39 fits into 252 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 234 from 252 leaves us with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 39

Going ahead to step 4:
The number 39 fits into 183 4 times, leaving a remainder of 27.
The next digit of our result is 4. 
Result so far: 164.0
Deduct 156 from 183 and we're left with 27.
Take the next digit (4) from the dividend and append it to 27, then repeat: 274 / 39

Let's proceed to step 5:
When dividing 274 by 39, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1647.0
If we take 273 away from 274, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 39

Step 6:
The number 39 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 16470.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
The number 39 fits into 180 4 times, leaving a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 16470.4
If we take 156 away from 180, 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.

Let's proceed to step 8:
If we divide 240 by 39, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 16470.46
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
39 can be fit into 60 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 16470.461
Deduct 39 from 60 and we're left 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.

Let's proceed to step 10:
39 goes into 210 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 16470.4615
Subtracting 195 from 210 leaves us 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 11:
39 can be fit into 150 3 times, resulting in a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 16470.46153
Subtract 117 from 150 to 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.

On to step 12:
The number 39 fits into 330 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 16470.461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 13:
39 goes into 180 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 16470.4615384
Subtracting 156 from 180 leaves us 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.

Let's proceed to step 14:
39 goes into 240 6 times with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 16470.46153846
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 16470.46153846 with a remainder of 6e-09.
