31430287 ÷ 54 
We're looking to find how many times 54 goes into 31430287.

Step 1:
If we divide 3 by 54, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 54

Moving on to step 2:
When dividing 31 by 54, we get 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 54

Step 3:
314 divided by 54 is 5 with a remainder of 44.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 44 after subtracting 270 from 314.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 54

Let's proceed to step 4:
When dividing 443 by 54, we get 8 with a remainder of 11.
Use 8 as the next digit of our solution. 
Result so far: 58.0
If we take 432 away from 443, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 54

Going ahead to step 5:
When dividing 110 by 54, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 582.0
Subtracting 108 from 110 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 54

Step 6:
The number 54 fits into 22 0 times, leaving a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 5820.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 54

Moving on to step 7:
The number 54 fits into 228 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 58204.0
If we subtract 216 from 228, we get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 54

Moving on to step 8:
The number 54 fits into 127 2 times, leaving a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 582042.0
If we take 108 away from 127, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
When dividing 190 by 54, we get 3 with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 582042.3
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
54 can be fit into 280 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 582042.35
Subtract 270 from 280 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 11:
54 goes into 100 1 times with a remainder of 46.
The next digit of our result is 1. 
Result so far: 582042.351
Subtracting 54 from 100 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
460 divided by 54 is 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 582042.3518
If we take 432 away from 460, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
54 can be fit into 280 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 582042.35185
If we subtract 270 from 280, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
100 divided by 54 is 1 with a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 582042.351851
Subtract 54 from 100 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 15:
If we divide 460 by 54, we get 8 and a remainder of 28.
Write down 8 as next digit of the result. 
Result so far: 582042.3518518
Subtracting 432 from 460 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 16:
54 can be fit into 280 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 582042.35185185
Subtract 270 from 280 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 582042.35185185 with a remainder of 1e-08.
