Let's divide 103939 by 54
We want to divide 103939 by 54.

On to step 1:
If we divide 1 by 54, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 54

On to step 2:
54 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 54

Advancing to step 3:
103 divided by 54 is 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 54 away from 103, we end up with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 54

Let's proceed to step 4:
54 can be fit into 499 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 486 from 499 to get 13.
Fetch the next digit (3) from the dividend, attach it to 13 and continue: 133 / 54

Advancing to step 5:
When dividing 133 by 54, we get 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
If we take 108 away from 133, we end up with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 54

Going ahead to step 6:
54 can be fit into 259 4 times, resulting in a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 1924.0
If we subtract 216 from 259, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
If we divide 430 by 54, we get 7 and a remainder of 52.
Write down 7 as next digit of the result. 
Result so far: 1924.7
If we subtract 378 from 430, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
When dividing 520 by 54, we get 9 with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 1924.79
Deduct 486 from 520 and we're left with 34.
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 9:
If we divide 340 by 54, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1924.796
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 54 is 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 1924.7962
If we subtract 108 from 160, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 11:
When dividing 520 by 54, we get 9 with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 1924.79629
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
If we divide 340 by 54, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 1924.796296
If we take 324 away from 340, 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.

Step 13:
54 can be fit into 160 2 times, resulting in a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 1924.7962962
Subtract 108 from 160 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 14:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 1924.79629629
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 1924.79629629 with a remaining 3.4e-08.
