We look at the division of 402725 by 39 
We want to divide 402725 by 39.

Step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 39

Advancing to step 2:
The number 39 fits into 40 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 39 from 40 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 39

Going ahead to step 3:
39 goes into 12 0 times with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 39

Let's proceed to step 4:
If we divide 127 by 39, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
The remainder is 10 after subtracting 117 from 127.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 39

Going ahead to step 5:
39 goes into 102 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 1032.0
The remainder is 24 after subtracting 78 from 102.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 39

On to step 6:
When dividing 245 by 39, we get 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 10326.0
Subtracting 234 from 245 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
110 divided by 39 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 10326.2
Deduct 78 from 110 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
39 can be fit into 320 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 10326.28
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
The number 39 fits into 80 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 10326.282
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
When dividing 20 by 39, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10326.282
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
The number 39 fits into 200 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10326.28205
Subtract 195 from 200 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
The number 39 fits into 50 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 10326.282051
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
If we divide 110 by 39, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 10326.2820512
Subtract 78 from 110 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
If we divide 320 by 39, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 10326.28205128
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 10326.28205128 with a remaining 8e-09.
