We divide 486792 by 39
We want to figure out the number of times 486792 can be divided by 39.

Step 1:
The number 39 fits into 4 0 times, leaving 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.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 39

On to step 2:
When dividing 48 by 39, we get 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 9 after subtracting 39 from 48.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 39

Let's proceed to step 3:
39 goes into 96 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 18 after subtracting 78 from 96.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 39

Let's proceed to step 4:
If we divide 187 by 39, we get 4 and a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Deduct 156 from 187 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 39

Advancing to step 5:
The number 39 fits into 319 8 times, leaving a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 1248.0
Deduct 312 from 319 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 39

Let's proceed to step 6:
39 can be fit into 72 1 times, resulting in a remainder of 33.
The next digit of our result is 1. 
Result so far: 12481.0
Subtract 39 from 72 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
330 divided by 39 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 12481.8
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
If we divide 180 by 39, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 12481.84
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
39 goes into 240 6 times with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 12481.846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
39 can be fit into 60 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 12481.8461
If we subtract 39 from 60, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
When dividing 210 by 39, we get 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 12481.84615
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 12:
When dividing 150 by 39, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 12481.846153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
When dividing 330 by 39, we get 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 12481.8461538
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
The number 39 fits into 180 4 times, leaving a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 12481.84615384
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 12481.84615384, and the remainder is 2.4e-08.
