We look at the division of 390019 by 48 
We're looking to find how many times 48 goes into 390019.

Step 1:
48 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 48

Advancing to step 2:
If we divide 39 by 48, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 48

Going ahead to step 3:
If we divide 390 by 48, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 384 from 390 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 48

Advancing to step 4:
48 goes into 60 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 81.0
If we subtract 48 from 60, we get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 48

Going ahead to step 5:
121 divided by 48 is 2 with a remainder of 25.
The next digit of our result is 2. 
Result so far: 812.0
Deduct 96 from 121 and we're left with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 48

On to step 6:
48 goes into 259 5 times with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 8125.0
If we take 240 away from 259, 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.

Moving on to step 7:
When dividing 190 by 48, we get 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 8125.3
If we take 144 away from 190, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
48 goes into 460 9 times with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 8125.39
If we take 432 away from 460, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
When dividing 280 by 48, we get 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 8125.395
The remainder is 40 after subtracting 240 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 48 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 8125.3958
If we take 384 away from 400, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
If we divide 160 by 48, we get 3 and a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 8125.39583
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
The number 48 fits into 160 3 times, leaving a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 8125.395833
If we take 144 away from 160, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 8125.395833 with a remaining 1.6e-06.
