We're dividing 209957 by 54 
Our goal is to divide 209957 by 54.

Step 1:
The number 54 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 54

Let's proceed to step 2:
20 divided by 54 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 54

Let's proceed to step 3:
If we divide 209 by 54, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 162 from 209 leaves us with 47.
Grab the next digit (9) from the dividend, add it to 47, then carry on: 479 / 54

Let's proceed to step 4:
54 can be fit into 479 8 times, resulting in a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 38.0
If we take 432 away from 479, we end up with 47.
Grab the next digit (5) from the dividend, add it to 47, then carry on: 475 / 54

On to step 5:
If we divide 475 by 54, we get 8 and a remainder of 43.
The number 8 becomes the next digit in our result. 
Result so far: 388.0
Subtract 432 from 475 to get 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 54

Step 6:
437 divided by 54 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 3888.0
Deduct 432 from 437 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
54 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3888.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
The number 54 fits into 500 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 3888.09
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
54 goes into 140 2 times with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 3888.092
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
54 can be fit into 320 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3888.0925
Subtract 270 from 320 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 11:
When dividing 500 by 54, we get 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 3888.09259
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
140 divided by 54 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 3888.092592
Deduct 108 from 140 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
54 goes into 320 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3888.0925925
Subtracting 270 from 320 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
54 goes into 500 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 3888.09259259
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 3888.09259259, with a leftover of 1.4e-08.
