900255 ÷ 39 
Our goal is to divide 900255 by 39.

Step 1:
39 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 39

Going ahead to step 2:
39 can be fit into 90 2 times, resulting in a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 78 from 90 leaves us with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 39

Step 3:
39 goes into 120 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 23.0
The remainder is 3 after subtracting 117 from 120.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 39

Moving on to step 4:
The number 39 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 230.0
Deduct 0 from 32 and we're left with 32.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 39

Going ahead to step 5:
The number 39 fits into 325 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 2308.0
Subtracting 312 from 325 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 39

Going ahead to step 6:
When dividing 135 by 39, we get 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 23083.0
If we subtract 117 from 135, 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.

Let's proceed to step 7:
180 divided by 39 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 23083.4
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.

On to step 8:
The number 39 fits into 240 6 times, leaving a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 23083.46
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.

Step 9:
The number 39 fits into 60 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 23083.461
If we subtract 39 from 60, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
39 can be fit into 210 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 23083.4615
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.

Let's proceed to step 11:
When dividing 150 by 39, we get 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 23083.46153
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.

Let's proceed to step 12:
39 can be fit into 330 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 23083.461538
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 can be fit into 180 4 times, resulting in a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 23083.4615384
Deduct 156 from 180 and we're left 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.

Moving on to step 14:
When dividing 240 by 39, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 23083.46153846
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.

In conclusion, the division gives 23083.46153846 with a balance of 6e-09.
