We look at the division of 31392429 by 654 
We're looking to find how many times 654 goes into 31392429.

Moving on to step 1:
654 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 654

Step 2:
654 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 654

On to step 3:
654 can be fit into 313 0 times, resulting in a remainder of 313.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 313, we end up with 313.
Take the next digit (9) from the dividend and append it to 313, then repeat: 3139 / 654

Step 4:
When dividing 3139 by 654, we get 4 with a remainder of 523.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 2616 from 3139 to get 523.
Grab the next digit (2) from the dividend, add it to 523, then carry on: 5232 / 654

Let's proceed to step 5:
654 can be fit into 5232 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 5232 from 5232 leaves us with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 654

Step 6:
The number 654 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 480.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 654

Step 7:
When dividing 42 by 654, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 4800.0
Subtract 0 from 42 to get 42.
Bring next digit (9) of the dividend behind the 42 and repeat the process: 429 / 654

On to step 8:
654 goes into 429 0 times with a remainder of 429.
Record the quotient 0 as the next digit in the result. 
Result so far: 48000.0
If we subtract 0 from 429, we get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
When dividing 4290 by 654, we get 6 with a remainder of 366.
Use 6 as the next digit of our solution. 
Result so far: 48000.6
Subtract 3924 from 4290 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 10:
3660 divided by 654 is 5 with a remainder of 390.
Put 5 as the next digit of the answer. 
Result so far: 48000.65
If we subtract 3270 from 3660, we get 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

On to step 11:
When dividing 3900 by 654, we get 5 with a remainder of 630.
The next digit of our result is 5. 
Result so far: 48000.655
Subtracting 3270 from 3900 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

In conclusion, the division gives 48000.655 with a balance of 0.063.
