423489 ÷ 39 
Let's see how many times 39 fits into 423489.

On to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 39

Going ahead to step 2:
39 can be fit into 42 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 39 from 42 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 39

Going ahead to step 3:
39 goes into 33 0 times with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 39

Let's proceed to step 4:
If we divide 334 by 39, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 312 away from 334, we end up with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 39

Advancing to step 5:
39 can be fit into 228 5 times, resulting in a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 1085.0
The remainder is 33 after subtracting 195 from 228.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 39

Moving on to step 6:
339 divided by 39 is 8 with a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 10858.0
Subtract 312 from 339 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 39, we get 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 10858.6
Subtracting 234 from 270 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 8:
If we divide 360 by 39, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 10858.69
If we take 351 away from 360, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
The number 39 fits into 90 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 10858.692
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
120 divided by 39 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 10858.6923
Subtract 117 from 120 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
When dividing 30 by 39, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10858.6923
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
300 divided by 39 is 7 with a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 10858.692307
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 13:
270 divided by 39 is 6 with a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 10858.6923076
Deduct 234 from 270 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
If we divide 360 by 39, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 10858.69230769
If we subtract 351 from 360, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 10858.69230769 with a balance of 9e-09.
