We look at the division of 30517421 by 924 
We want to figure out the number of times 30517421 can be divided by 924.

Step 1:
924 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 924

Advancing to step 2:
924 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (5) from the dividend and append it to 30, then repeat: 305 / 924

On to step 3:
The number 924 fits into 305 0 times, leaving a remainder of 305.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 305 leaves us with 305.
Fetch the next digit (1) from the dividend, attach it to 305 and continue: 3051 / 924

Step 4:
924 can be fit into 3051 3 times, resulting in a remainder of 279.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 2772 from 3051, we get 279.
Grab the next digit (7) from the dividend, add it to 279, then carry on: 2797 / 924

Let's proceed to step 5:
When dividing 2797 by 924, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we take 2772 away from 2797, we end up with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 924

Moving on to step 6:
The number 924 fits into 254 0 times, leaving a remainder of 254.
Use 0 as the next digit of our solution. 
Result so far: 330.0
If we subtract 0 from 254, we get 254.
Grab the next digit (2) from the dividend, add it to 254, then carry on: 2542 / 924

Moving on to step 7:
The number 924 fits into 2542 2 times, leaving a remainder of 694.
The next digit of our result is 2. 
Result so far: 3302.0
If we subtract 1848 from 2542, we get 694.
Take the next digit (1) from the dividend and append it to 694, then repeat: 6941 / 924

On to step 8:
924 can be fit into 6941 7 times, resulting in a remainder of 473.
Use 7 as the next digit of our solution. 
Result so far: 33027.0
If we take 6468 away from 6941, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Let's proceed to step 9:
If we divide 4730 by 924, we get 5 and a remainder of 110.
The next digit of our result is 5. 
Result so far: 33027.5
The remainder is 110 after subtracting 4620 from 4730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 10:
924 goes into 1100 1 times with a remainder of 176.
Record the quotient 1 as the next digit in the result. 
Result so far: 33027.51
Deduct 924 from 1100 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 11:
924 can be fit into 1760 1 times, resulting in a remainder of 836.
Use 1 as the next digit of our solution. 
Result so far: 33027.511
If we take 924 away from 1760, we end up with 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

The final result is 33027.511 with a remainder of 0.0836.
