We divide 645974 by 54
We want to divide 645974 by 54.

Moving on to step 1:
If we divide 6 by 54, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 54

On to step 2:
The number 54 fits into 64 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 54 from 64 to get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 54

Moving on to step 3:
When dividing 105 by 54, we get 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 54 from 105, we get 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 54

Going ahead to step 4:
If we divide 519 by 54, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
Subtract 486 from 519 to get 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 54

Moving on to step 5:
54 can be fit into 337 6 times, resulting in a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 1196.0
Deduct 324 from 337 and we're left with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 54

Step 6:
If we divide 134 by 54, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 11962.0
The remainder is 26 after subtracting 108 from 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
If we divide 260 by 54, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11962.4
If we take 216 away from 260, we end up 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.

Let's proceed to step 8:
The number 54 fits into 440 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11962.48
If we take 432 away from 440, we end up 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.

Moving on to step 9:
54 goes into 80 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11962.481
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.

Moving on to step 10:
If we divide 260 by 54, we get 4 and a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 11962.4814
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.

Step 11:
If we divide 440 by 54, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 11962.48148
If we take 432 away from 440, we end up 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.

Moving on to step 12:
The number 54 fits into 80 1 times, leaving a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 11962.481481
If we take 54 away from 80, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
If we divide 260 by 54, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 11962.4814814
If we subtract 216 from 260, we 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.

Moving on to step 14:
When dividing 440 by 54, we get 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 11962.48148148
Subtracting 432 from 440 leaves us 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.

In conclusion, the division gives 11962.48148148 with a balance of 8e-09.
