We're dividing 54339507 by 924 
We want to figure out the number of times 54339507 can be divided by 924.

Step 1:
The number 924 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 924

Moving on to step 2:
924 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 924

On to step 3:
The number 924 fits into 543 0 times, leaving a remainder of 543.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 543 after subtracting 0 from 543.
Bring next digit (3) of the dividend behind the 543 and repeat the process: 5433 / 924

Advancing to step 4:
If we divide 5433 by 924, we get 5 and a remainder of 813.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 4620 from 5433 leaves us with 813.
Bring next digit (9) of the dividend behind the 813 and repeat the process: 8139 / 924

On to step 5:
924 goes into 8139 8 times with a remainder of 747.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtract 7392 from 8139 to get 747.
Bring next digit (5) of the dividend behind the 747 and repeat the process: 7475 / 924

On to step 6:
924 can be fit into 7475 8 times, resulting in a remainder of 83.
Record the quotient 8 as the next digit in the result. 
Result so far: 588.0
Deduct 7392 from 7475 and we're left with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 924

Advancing to step 7:
When dividing 830 by 924, we get 0 with a remainder of 830.
Use 0 as the next digit of our solution. 
Result so far: 5880.0
Subtracting 0 from 830 leaves us with 830.
Append the next digit (7) from the dividend to 830 and continue with: 8307 / 924

On to step 8:
If we divide 8307 by 924, we get 8 and a remainder of 915.
Write down 8 as next digit of the result. 
Result so far: 58808.0
If we subtract 7392 from 8307, we get 915.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9150, and continue the process.

On to step 9:
If we divide 9150 by 924, we get 9 and a remainder of 834.
Record the quotient 9 as the next digit in the result. 
Result so far: 58808.9
If we subtract 8316 from 9150, we get 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Advancing to step 10:
924 can be fit into 8340 9 times, resulting in a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 58808.99
The remainder is 24 after subtracting 8316 from 8340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 58808.99 with a remainder of 0.024.
