Let's divide 103893 by 51
Let's see how many times 51 fits into 103893.

On to step 1:
When dividing 1 by 51, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 51

Step 2:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 51

Going ahead to step 3:
When dividing 103 by 51, we get 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 102 from 103 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 51

Step 4:
When dividing 18 by 51, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Deduct 0 from 18 and we're left with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 51

Step 5:
51 can be fit into 189 3 times, resulting in a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 203.0
If we subtract 153 from 189, we get 36.
Grab the next digit (3) from the dividend, add it to 36, then carry on: 363 / 51

Advancing to step 6:
363 divided by 51 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 2037.0
The remainder is 6 after subtracting 357 from 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 51, we get 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 2037.1
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
If we divide 90 by 51, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 2037.11
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 2037.11 and a remainder of 0.039.
