We look at the division of 543912 by 55 
We want to figure out the number of times 543912 can be divided by 55.

Moving on to step 1:
55 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 55

Going ahead to step 2:
55 can be fit into 54 0 times, resulting in a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 55

On to step 3:
The number 55 fits into 543 9 times, leaving a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 495 from 543 to get 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 55

Moving on to step 4:
If we divide 489 by 55, we get 8 and a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we subtract 440 from 489, we get 49.
Take the next digit (1) from the dividend and append it to 49, then repeat: 491 / 55

Advancing to step 5:
When dividing 491 by 55, we get 8 with a remainder of 51.
Write down 8 as next digit of the result. 
Result so far: 988.0
If we take 440 away from 491, we end up with 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 55

Moving on to step 6:
55 can be fit into 512 9 times, resulting in a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 9889.0
If we subtract 495 from 512, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
The number 55 fits into 170 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 9889.3
If we subtract 165 from 170, we get 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 8:
55 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 9889.3
If we subtract 0 from 50, we 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.

Moving on to step 9:
When dividing 500 by 55, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 9889.309
Subtract 495 from 500 to get 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 10:
50 divided by 55 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 9889.309
If we subtract 0 from 50, we 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.

On to step 11:
When dividing 500 by 55, we get 9 with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 9889.30909
If we take 495 away from 500, we end up 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.

On to step 12:
55 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9889.30909
Subtracting 0 from 50 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.

Advancing to step 13:
55 goes into 500 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 9889.3090909
Deduct 495 from 500 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.

Moving on to step 14:
55 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 9889.3090909
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.

The final outcome is 9889.3090909, with a leftover of 5e-08.
