We're dividing 55842 by 51 
We want to figure out the number of times 55842 can be divided by 51.

Step 1:
51 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 51

Let's proceed to step 2:
55 divided by 51 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 51 from 55, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 51

Let's proceed to step 3:
When dividing 48 by 51, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 48 and we're left with 48.
Fetch the next digit (4) from the dividend, attach it to 48 and continue: 484 / 51

On to step 4:
The number 51 fits into 484 9 times, leaving a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 459 from 484, we get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 51

Advancing to step 5:
252 divided by 51 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 1094.0
Subtracting 204 from 252 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 6:
51 goes into 480 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 1094.9
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
210 divided by 51 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 1094.94
Subtract 204 from 210 to get 6.
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 8:
60 divided by 51 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1094.941
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 9:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1094.9411
Deduct 51 from 90 and we're left with 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 1094.9411 and a remainder of 0.00039.
