486322 ÷ 39 
Our goal is to divide 486322 by 39.

Going ahead to step 1:
If we divide 4 by 39, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 39

Step 2:
39 can be fit into 48 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 9 after subtracting 39 from 48.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 39

Let's proceed to step 3:
39 goes into 96 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 78 from 96 leaves us with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 39

Let's proceed to step 4:
When dividing 183 by 39, we get 4 with a remainder of 27.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 156 from 183 leaves us with 27.
Include the next digit (2) from the dividend after 27, then repeat: 272 / 39

On to step 5:
The number 39 fits into 272 6 times, leaving a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 1246.0
Subtract 234 from 272 to get 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 39

Step 6:
39 can be fit into 382 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 12469.0
If we subtract 351 from 382, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
39 goes into 310 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 12469.7
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 8:
39 can be fit into 370 9 times, resulting in a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 12469.79
The remainder is 19 after subtracting 351 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 9:
When dividing 190 by 39, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 12469.794
The remainder is 34 after subtracting 156 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
39 can be fit into 340 8 times, resulting in a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 12469.7948
Subtract 312 from 340 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
The number 39 fits into 280 7 times, leaving a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 12469.79487
The remainder is 7 after subtracting 273 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
When dividing 70 by 39, we get 1 with a remainder of 31.
The next digit of our result is 1. 
Result so far: 12469.794871
If we take 39 away from 70, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
The number 39 fits into 310 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 12469.7948717
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 14:
39 goes into 370 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 12469.79487179
If we take 351 away from 370, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 12469.79487179 with a balance of 1.9e-08.
