629739 divided by 54 
Our goal is to divide 629739 by 54.

Step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 54

Advancing to step 2:
If we divide 62 by 54, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 54 from 62 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 54

Going ahead to step 3:
The number 54 fits into 89 1 times, leaving a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 54 from 89, we get 35.
Append the next digit (7) from the dividend to 35 and continue with: 357 / 54

Moving on to step 4:
The number 54 fits into 357 6 times, leaving a remainder of 33.
Use 6 as the next digit of our solution. 
Result so far: 116.0
The remainder is 33 after subtracting 324 from 357.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 54

On to step 5:
333 divided by 54 is 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 1166.0
If we take 324 away from 333, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 54

Advancing to step 6:
The number 54 fits into 99 1 times, leaving a remainder of 45.
The next digit of our result is 1. 
Result so far: 11661.0
Deduct 54 from 99 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
The number 54 fits into 450 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 11661.8
Subtract 432 from 450 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
If we divide 180 by 54, we get 3 and a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 11661.83
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
54 can be fit into 180 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 11661.833
If we subtract 162 from 180, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 11661.833, with a leftover of 0.0018.
