We're dividing 428997 by 39 
Let's see how many times 39 fits into 428997.

Advancing to step 1:
39 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 39

Step 2:
If we divide 42 by 39, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 39 from 42 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 39

Advancing to step 3:
If we divide 38 by 39, we get 0 and a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 38 after subtracting 0 from 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 39

Let's proceed to step 4:
39 goes into 389 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 109.0
If we subtract 351 from 389, we get 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 39

Going ahead to step 5:
389 divided by 39 is 9 with a remainder of 38.
The next digit of our result is 9. 
Result so far: 1099.0
Deduct 351 from 389 and we're left with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 39

Step 6:
If we divide 387 by 39, we get 9 and a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 10999.0
Subtract 351 from 387 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 39 fits into 360 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 10999.9
Subtract 351 from 360 to 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.

Step 8:
90 divided by 39 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 10999.92
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
When dividing 120 by 39, we get 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 10999.923
Subtracting 117 from 120 leaves us with 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 10:
39 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 10999.923
Subtracting 0 from 30 leaves us 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.

On to step 11:
When dividing 300 by 39, we get 7 with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 10999.92307
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.

Going ahead to step 12:
270 divided by 39 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 10999.923076
The remainder is 36 after subtracting 234 from 270.
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 13:
39 can be fit into 360 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 10999.9230769
Subtract 351 from 360 to 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.

Let's proceed to step 14:
90 divided by 39 is 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 10999.92307692
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 10999.92307692 with a balance of 1.2e-08.
