642895 ÷ 39 
We want to divide 642895 by 39.

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.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 39

Going ahead to step 2:
If we divide 64 by 39, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 25 after subtracting 39 from 64.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 39

Step 3:
If we divide 252 by 39, we get 6 and a remainder of 18.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 234 from 252 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 39

Let's proceed to step 4:
The number 39 fits into 188 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtracting 156 from 188 leaves us with 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 39

Going ahead to step 5:
39 can be fit into 329 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 1648.0
Subtract 312 from 329 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 39

Advancing to step 6:
If we divide 175 by 39, we get 4 and a remainder of 19.
Put 4 as the next digit of the answer. 
Result so far: 16484.0
The remainder is 19 after subtracting 156 from 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 39 is 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 16484.4
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 16484.48
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
280 divided by 39 is 7 with a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 16484.487
If we subtract 273 from 280, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
39 goes into 70 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 16484.4871
The remainder is 31 after subtracting 39 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
39 goes into 310 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 16484.48717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 12:
370 divided by 39 is 9 with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 16484.487179
Deduct 351 from 370 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 13:
39 goes into 190 4 times with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 16484.4871794
Subtracting 156 from 190 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 14:
When dividing 340 by 39, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 16484.48717948
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 16484.48717948 with a remainder of 2.8e-08.
