We're dividing 438590 by 39 
We're looking to find how many times 39 goes into 438590.

Moving on to step 1:
When dividing 4 by 39, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 39

Going ahead to step 2:
43 divided by 39 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 39 from 43, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 39

Moving on to step 3:
If we divide 48 by 39, we get 1 and a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 9 after subtracting 39 from 48.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 39

Moving on to step 4:
95 divided by 39 is 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Deduct 78 from 95 and we're left with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 39

Moving on to step 5:
When dividing 179 by 39, we get 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 1124.0
Subtracting 156 from 179 leaves us with 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 39

Step 6:
When dividing 230 by 39, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 11245.0
Subtracting 195 from 230 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
39 goes into 350 8 times with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 11245.8
Subtracting 312 from 350 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
39 can be fit into 380 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 11245.89
Subtracting 351 from 380 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
39 goes into 290 7 times with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 11245.897
If we take 273 away from 290, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
The number 39 fits into 170 4 times, leaving a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 11245.8974
If we take 156 away from 170, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
The number 39 fits into 140 3 times, leaving a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 11245.89743
The remainder is 23 after subtracting 117 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
If we divide 230 by 39, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 11245.897435
If we take 195 away from 230, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 13:
When dividing 350 by 39, we get 8 with a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 11245.8974358
Subtract 312 from 350 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
The number 39 fits into 380 9 times, leaving a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 11245.89743589
The remainder is 29 after subtracting 351 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 11245.89743589, with a leftover of 2.9e-08.
