We're dividing 12764754 by 623 
We want to divide 12764754 by 623.

Step 1:
If we divide 1 by 623, we get 0 and a remainder of 1.
The next digit of our result is 0. 
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 / 623

Advancing to step 2:
623 can be fit into 12 0 times, resulting in a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 623

Going ahead to step 3:
If we divide 127 by 623, we get 0 and a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 127 to get 127.
Grab the next digit (6) from the dividend, add it to 127, then carry on: 1276 / 623

Let's proceed to step 4:
1276 divided by 623 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1246 from 1276 leaves us with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 623

Going ahead to step 5:
The number 623 fits into 304 0 times, leaving a remainder of 304.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 304 and we're left with 304.
Take the next digit (7) from the dividend and append it to 304, then repeat: 3047 / 623

Let's proceed to step 6:
If we divide 3047 by 623, we get 4 and a remainder of 555.
Use 4 as the next digit of our solution. 
Result so far: 204.0
The remainder is 555 after subtracting 2492 from 3047.
Append the next digit (5) from the dividend to 555 and continue with: 5555 / 623

Going ahead to step 7:
When dividing 5555 by 623, we get 8 with a remainder of 571.
Write down 8 as next digit of the result. 
Result so far: 2048.0
If we subtract 4984 from 5555, we get 571.
Append the next digit (4) from the dividend to 571 and continue with: 5714 / 623

Let's proceed to step 8:
If we divide 5714 by 623, we get 9 and a remainder of 107.
The number 9 becomes the next digit in our result. 
Result so far: 20489.0
Deduct 5607 from 5714 and we're left with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 9:
1070 divided by 623 is 1 with a remainder of 447.
Write down 1 as next digit of the result. 
Result so far: 20489.1
Deduct 623 from 1070 and we're left with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 10:
4470 divided by 623 is 7 with a remainder of 109.
Put 7 as the next digit of the answer. 
Result so far: 20489.17
Deduct 4361 from 4470 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 11:
623 can be fit into 1090 1 times, resulting in a remainder of 467.
The number 1 becomes the next digit in our result. 
Result so far: 20489.171
The remainder is 467 after subtracting 623 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Moving on to step 12:
4670 divided by 623 is 7 with a remainder of 309.
The next digit of our result is 7. 
Result so far: 20489.1717
If we subtract 4361 from 4670, we get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 13:
3090 divided by 623 is 4 with a remainder of 598.
The number 4 becomes the next digit in our result. 
Result so far: 20489.17174
If we subtract 2492 from 3090, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 14:
If we divide 5980 by 623, we get 9 and a remainder of 373.
The number 9 becomes the next digit in our result. 
Result so far: 20489.171749
Subtract 5607 from 5980 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 15:
3730 divided by 623 is 5 with a remainder of 615.
The number 5 becomes the next digit in our result. 
Result so far: 20489.1717495
Subtracting 3115 from 3730 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 16:
If we divide 6150 by 623, we get 9 and a remainder of 543.
The number 9 becomes the next digit in our result. 
Result so far: 20489.17174959
If we subtract 5607 from 6150, we get 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

After the division, we end up with 20489.17174959 and a remainder of 5.43e-07.
