Let's divide 172780 by 54
We want to divide 172780 by 54.

Step 1:
If we divide 1 by 54, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 54

Moving on to step 2:
54 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 54

Moving on to step 3:
The number 54 fits into 172 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 162 away from 172, we end up with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 54

Let's proceed to step 4:
54 can be fit into 107 1 times, resulting in a remainder of 53.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 54 away from 107, we end up with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 54

Advancing to step 5:
54 can be fit into 538 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 319.0
Subtract 486 from 538 to get 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 54

On to step 6:
54 can be fit into 520 9 times, resulting in a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 3199.0
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
When dividing 340 by 54, we get 6 with a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 3199.6
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
When dividing 160 by 54, we get 2 with a remainder of 52.
The next digit of our result is 2. 
Result so far: 3199.62
Deduct 108 from 160 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
When dividing 520 by 54, we get 9 with a remainder of 34.
The next digit of our result is 9. 
Result so far: 3199.629
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
The number 54 fits into 340 6 times, leaving a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 3199.6296
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 54, we get 2 and a remainder of 52.
Use 2 as the next digit of our solution. 
Result so far: 3199.62962
If we subtract 108 from 160, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
54 goes into 520 9 times with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 3199.629629
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
When dividing 340 by 54, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3199.6296296
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 14:
The number 54 fits into 160 2 times, leaving a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 3199.62962962
If we subtract 108 from 160, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final result is 3199.62962962 with a remainder of 5.2e-08.
