Let's divide 493645 by 39
We're looking to find how many times 39 goes into 493645.

Step 1:
39 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 39

On to step 2:
49 divided by 39 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 39 from 49 leaves us with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 39

On to step 3:
If we divide 103 by 39, we get 2 and a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 78 from 103 leaves us with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 39

Step 4:
If we divide 256 by 39, we get 6 and a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Subtract 234 from 256 to get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 39

Advancing to step 5:
The number 39 fits into 224 5 times, leaving a remainder of 29.
Put 5 as the next digit of the answer. 
Result so far: 1265.0
Subtracting 195 from 224 leaves us with 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 39

Moving on to step 6:
When dividing 295 by 39, we get 7 with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 12657.0
The remainder is 22 after subtracting 273 from 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
The number 39 fits into 220 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 12657.5
Deduct 195 from 220 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
250 divided by 39 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 12657.56
Subtract 234 from 250 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 39, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 12657.564
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
39 goes into 40 1 times with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 12657.5641
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
The number 39 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 12657.5641
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
If we divide 100 by 39, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 12657.564102
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
39 goes into 220 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 12657.5641025
If we subtract 195 from 220, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
The number 39 fits into 250 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 12657.56410256
The remainder is 16 after subtracting 234 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 12657.56410256, with a leftover of 1.6e-08.
