We're dividing 12993469 by 435 
Let's see how many times 435 fits into 12993469.

Going ahead to step 1:
When dividing 1 by 435, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 435

Advancing to step 2:
435 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 435

Let's proceed to step 3:
435 can be fit into 129 0 times, resulting in a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Grab the next digit (9) from the dividend, add it to 129, then carry on: 1299 / 435

Step 4:
When dividing 1299 by 435, we get 2 with a remainder of 429.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 870 from 1299, we get 429.
Grab the next digit (3) from the dividend, add it to 429, then carry on: 4293 / 435

Advancing to step 5:
The number 435 fits into 4293 9 times, leaving a remainder of 378.
Write down 9 as next digit of the result. 
Result so far: 29.0
The remainder is 378 after subtracting 3915 from 4293.
Grab the next digit (4) from the dividend, add it to 378, then carry on: 3784 / 435

Advancing to step 6:
435 can be fit into 3784 8 times, resulting in a remainder of 304.
Put 8 as the next digit of the answer. 
Result so far: 298.0
If we take 3480 away from 3784, we end up with 304.
Include the next digit (6) from the dividend after 304, then repeat: 3046 / 435

Moving on to step 7:
435 goes into 3046 7 times with a remainder of 1.
The next digit of our result is 7. 
Result so far: 2987.0
If we take 3045 away from 3046, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 435

Let's proceed to step 8:
If we divide 19 by 435, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 29870.0
Subtracting 0 from 19 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
435 goes into 190 0 times with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 29870.0
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 10:
1900 divided by 435 is 4 with a remainder of 160.
The next digit of our result is 4. 
Result so far: 29870.04
If we take 1740 away from 1900, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 11:
1600 divided by 435 is 3 with a remainder of 295.
The number 3 becomes the next digit in our result. 
Result so far: 29870.043
Deduct 1305 from 1600 and we're left with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Going ahead to step 12:
435 goes into 2950 6 times with a remainder of 340.
The next digit of our result is 6. 
Result so far: 29870.0436
If we take 2610 away from 2950, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 13:
If we divide 3400 by 435, we get 7 and a remainder of 355.
Put 7 as the next digit of the answer. 
Result so far: 29870.04367
Deduct 3045 from 3400 and we're left with 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Step 14:
When dividing 3550 by 435, we get 8 with a remainder of 70.
The next digit of our result is 8. 
Result so far: 29870.043678
Deduct 3480 from 3550 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 15:
700 divided by 435 is 1 with a remainder of 265.
The number 1 becomes the next digit in our result. 
Result so far: 29870.0436781
Subtract 435 from 700 to get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 16:
The number 435 fits into 2650 6 times, leaving a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 29870.04367816
The remainder is 40 after subtracting 2610 from 2650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 29870.04367816, with a leftover of 4e-08.
