Let's see how many times 924 fits into 78403955.

Moving on to step 1:
The number 924 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 924

Advancing to step 2:
78 divided by 924 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 924

Advancing to step 3:
The number 924 fits into 784 0 times, leaving a remainder of 784.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 784 to get 784.
Take the next digit (0) from the dividend and append it to 784, then repeat: 7840 / 924

Let's proceed to step 4:
When dividing 7840 by 924, we get 8 with a remainder of 448.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 448 after subtracting 7392 from 7840.
Grab the next digit (3) from the dividend, add it to 448, then carry on: 4483 / 924

Advancing to step 5:
If we divide 4483 by 924, we get 4 and a remainder of 787.
Put 4 as the next digit of the answer. 
Result so far: 84.0
If we take 3696 away from 4483, we end up with 787.
Take the next digit (9) from the dividend and append it to 787, then repeat: 7879 / 924

Step 6:
When dividing 7879 by 924, we get 8 with a remainder of 487.
Record the quotient 8 as the next digit in the result. 
Result so far: 848.0
The remainder is 487 after subtracting 7392 from 7879.
Bring next digit (5) of the dividend behind the 487 and repeat the process: 4875 / 924

Advancing to step 7:
924 can be fit into 4875 5 times, resulting in a remainder of 255.
Write down 5 as next digit of the result. 
Result so far: 8485.0
Deduct 4620 from 4875 and we're left with 255.
Fetch the next digit (5) from the dividend, attach it to 255 and continue: 2555 / 924

Advancing to step 8:
924 can be fit into 2555 2 times, resulting in a remainder of 707.
Write down 2 as next digit of the result. 
Result so far: 84852.0
If we take 1848 away from 2555, we end up with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Moving on to step 9:
7070 divided by 924 is 7 with a remainder of 602.
Write down 7 as next digit of the result. 
Result so far: 84852.7
Deduct 6468 from 7070 and we're left with 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 10:
When dividing 6020 by 924, we get 6 with a remainder of 476.
Use 6 as the next digit of our solution. 
Result so far: 84852.76
Subtracting 5544 from 6020 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Advancing to step 11:
4760 divided by 924 is 5 with a remainder of 140.
The next digit of our result is 5. 
Result so far: 84852.765
If we take 4620 away from 4760, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 12:
1400 divided by 924 is 1 with a remainder of 476.
Put 1 as the next digit of the answer. 
Result so far: 84852.7651
If we subtract 924 from 1400, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 13:
When dividing 4760 by 924, we get 5 with a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 84852.76515
If we take 4620 away from 4760, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 14:
924 goes into 1400 1 times with a remainder of 476.
The number 1 becomes the next digit in our result. 
Result so far: 84852.765151
If we subtract 924 from 1400, we get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 15:
924 can be fit into 4760 5 times, resulting in a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 84852.7651515
Subtract 4620 from 4760 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
1400 divided by 924 is 1 with a remainder of 476.
The next digit of our result is 1. 
Result so far: 84852.76515151
Subtracting 924 from 1400 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

The final result is 84852.76515151 with a remainder of 4.76e-07.
