We're dividing 171998 by 54 
We're looking to find how many times 54 goes into 171998.

Advancing to step 1:
1 divided by 54 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 54

On to step 2:
The number 54 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 54

On to step 3:
54 goes into 171 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 162 from 171 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 54

On to step 4:
The number 54 fits into 99 1 times, leaving a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 45 after subtracting 54 from 99.
Take the next digit (9) from the dividend and append it to 45, then repeat: 459 / 54

Step 5:
If we divide 459 by 54, we get 8 and a remainder of 27.
The next digit of our result is 8. 
Result so far: 318.0
The remainder is 27 after subtracting 432 from 459.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 54

Let's proceed to step 6:
When dividing 278 by 54, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 3185.0
Subtract 270 from 278 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
80 divided by 54 is 1 with a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 3185.1
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
54 can be fit into 260 4 times, resulting in a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 3185.14
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
54 goes into 440 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3185.148
Deduct 432 from 440 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 54, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 3185.1481
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
54 goes into 260 4 times with a remainder of 44.
The next digit of our result is 4. 
Result so far: 3185.14814
Subtract 216 from 260 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 12:
54 can be fit into 440 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3185.148148
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
54 goes into 80 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 3185.1481481
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
When dividing 260 by 54, we get 4 with a remainder of 44.
The next digit of our result is 4. 
Result so far: 3185.14814814
Subtracting 216 from 260 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The final outcome is 3185.14814814, with a leftover of 4.4e-08.
