Let's divide 393553 by 48
We're looking to find how many times 48 goes into 393553.

Going ahead to step 1:
When dividing 3 by 48, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 48

Let's proceed to step 2:
When dividing 39 by 48, we get 0 with 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.
Fetch the next digit (3) from the dividend, attach it to 39 and continue: 393 / 48

Advancing to step 3:
393 divided by 48 is 8 with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 9 after subtracting 384 from 393.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 48

Going ahead to step 4:
48 can be fit into 95 1 times, resulting in a remainder of 47.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 48 from 95 and we're left with 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 48

On to step 5:
The number 48 fits into 475 9 times, leaving a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 819.0
The remainder is 43 after subtracting 432 from 475.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 48

Step 6:
If we divide 433 by 48, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8199.0
If we subtract 432 from 433, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 48 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 8199.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
48 can be fit into 100 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 8199.02
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
When dividing 40 by 48, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8199.02
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 48, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8199.0208
Subtracting 384 from 400 leaves us 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:
160 divided by 48 is 3 with a remainder of 16.
The next digit of our result is 3. 
Result so far: 8199.02083
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.

Advancing to step 12:
48 goes into 160 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 8199.020833
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 8199.020833, with a leftover of 1.6e-06.
