12605808 divided by 423 
We want to divide 12605808 by 423.

Let's proceed to step 1:
The number 423 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 423

Step 2:
The number 423 fits into 12 0 times, leaving 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.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 423

Advancing to step 3:
If we divide 126 by 423, we get 0 and a remainder of 126.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 126 to get 126.
Take the next digit (0) from the dividend and append it to 126, then repeat: 1260 / 423

Moving on to step 4:
423 goes into 1260 2 times with a remainder of 414.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 846 from 1260, we get 414.
Include the next digit (5) from the dividend after 414, then repeat: 4145 / 423

Going ahead to step 5:
The number 423 fits into 4145 9 times, leaving a remainder of 338.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 3807 from 4145 and we're left with 338.
Bring next digit (8) of the dividend behind the 338 and repeat the process: 3388 / 423

On to step 6:
If we divide 3388 by 423, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 298.0
If we take 3384 away from 3388, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 423

On to step 7:
The number 423 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2980.0
Subtract 0 from 40 to get 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 423

On to step 8:
When dividing 408 by 423, we get 0 with a remainder of 408.
Write down 0 as next digit of the result. 
Result so far: 29800.0
Deduct 0 from 408 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 9:
4080 divided by 423 is 9 with a remainder of 273.
Record the quotient 9 as the next digit in the result. 
Result so far: 29800.9
Subtract 3807 from 4080 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 10:
2730 divided by 423 is 6 with a remainder of 192.
Use 6 as the next digit of our solution. 
Result so far: 29800.96
Subtract 2538 from 2730 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 11:
1920 divided by 423 is 4 with a remainder of 228.
The next digit of our result is 4. 
Result so far: 29800.964
If we subtract 1692 from 1920, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 12:
When dividing 2280 by 423, we get 5 with a remainder of 165.
Record the quotient 5 as the next digit in the result. 
Result so far: 29800.9645
If we take 2115 away from 2280, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 13:
If we divide 1650 by 423, we get 3 and a remainder of 381.
Put 3 as the next digit of the answer. 
Result so far: 29800.96453
Subtracting 1269 from 1650 leaves us with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

On to step 14:
3810 divided by 423 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 29800.964539
The remainder is 3 after subtracting 3807 from 3810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 15:
423 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 29800.964539
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 16:
423 goes into 300 0 times with a remainder of 300.
The next digit of our result is 0. 
Result so far: 29800.964539
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The quotient of the division is 29800.964539, and the remainder is 3e-07.
