We look at the division of 51894 by 36 
We want to figure out the number of times 51894 can be divided by 36.

Step 1:
The number 36 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 36

Advancing to step 2:
When dividing 51 by 36, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 36 from 51 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 36

On to step 3:
If we divide 158 by 36, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 144 from 158, we get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 36

Advancing to step 4:
36 goes into 149 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 144.0
The remainder is 5 after subtracting 144 from 149.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 36

Moving on to step 5:
36 can be fit into 54 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 1441.0
If we subtract 36 from 54, we 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.

Going ahead to step 6:
180 divided by 36 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 1441.5
Subtracting 180 from 180 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 36 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1441.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 36, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1441.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 1441.5 and a remainder of 0.0.
