We're dividing 486869 by 39 
We want to divide 486869 by 39.

Step 1:
The number 39 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 39

Advancing to step 2:
48 divided by 39 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 39 from 48 and we're left with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 39

Moving on to step 3:
When dividing 96 by 39, we get 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 78 from 96 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 39

Let's proceed to step 4:
39 can be fit into 188 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we take 156 away from 188, we end up with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 39

Moving on to step 5:
If we divide 326 by 39, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 1248.0
The remainder is 14 after subtracting 312 from 326.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 39

Moving on to step 6:
39 goes into 149 3 times with a remainder of 32.
Use 3 as the next digit of our solution. 
Result so far: 12483.0
If we subtract 117 from 149, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
39 can be fit into 320 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 12483.8
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
39 goes into 80 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12483.82
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 39, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12483.82
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 39 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12483.8205
The remainder is 5 after subtracting 195 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
39 goes into 50 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 12483.82051
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
If we divide 110 by 39, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 12483.820512
Subtracting 78 from 110 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
If we divide 320 by 39, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 12483.8205128
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
If we divide 80 by 39, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 12483.82051282
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 12483.82051282 with a remaining 2e-09.
