We're dividing 12010488 by 623 
Our goal is to divide 12010488 by 623.

Step 1:
If we divide 1 by 623, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 623

Moving on to step 2:
The number 623 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 623

On to step 3:
When dividing 120 by 623, we get 0 with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Include the next digit (1) from the dividend after 120, then repeat: 1201 / 623

Moving on to step 4:
1201 divided by 623 is 1 with a remainder of 578.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 578 after subtracting 623 from 1201.
Grab the next digit (0) from the dividend, add it to 578, then carry on: 5780 / 623

Advancing to step 5:
623 goes into 5780 9 times with a remainder of 173.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 5607 from 5780 to get 173.
Bring next digit (4) of the dividend behind the 173 and repeat the process: 1734 / 623

On to step 6:
623 goes into 1734 2 times with a remainder of 488.
The next digit of our result is 2. 
Result so far: 192.0
Deduct 1246 from 1734 and we're left with 488.
Grab the next digit (8) from the dividend, add it to 488, then carry on: 4888 / 623

On to step 7:
The number 623 fits into 4888 7 times, leaving a remainder of 527.
Put 7 as the next digit of the answer. 
Result so far: 1927.0
Subtract 4361 from 4888 to get 527.
Fetch the next digit (8) from the dividend, attach it to 527 and continue: 5278 / 623

Step 8:
The number 623 fits into 5278 8 times, leaving a remainder of 294.
The number 8 becomes the next digit in our result. 
Result so far: 19278.0
Subtract 4984 from 5278 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 9:
623 can be fit into 2940 4 times, resulting in a remainder of 448.
The next digit of our result is 4. 
Result so far: 19278.4
Subtract 2492 from 2940 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 10:
623 can be fit into 4480 7 times, resulting in a remainder of 119.
Put 7 as the next digit of the answer. 
Result so far: 19278.47
If we subtract 4361 from 4480, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 11:
If we divide 1190 by 623, we get 1 and a remainder of 567.
Put 1 as the next digit of the answer. 
Result so far: 19278.471
Subtract 623 from 1190 to get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Moving on to step 12:
623 goes into 5670 9 times with a remainder of 63.
The next digit of our result is 9. 
Result so far: 19278.4719
Subtracting 5607 from 5670 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 13:
623 goes into 630 1 times with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 19278.47191
The remainder is 7 after subtracting 623 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
70 divided by 623 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 19278.47191
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 15:
If we divide 700 by 623, we get 1 and a remainder of 77.
The next digit of our result is 1. 
Result so far: 19278.4719101
If we take 623 away from 700, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 16:
The number 623 fits into 770 1 times, leaving a remainder of 147.
Put 1 as the next digit of the answer. 
Result so far: 19278.47191011
Subtracting 623 from 770 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Our division results in 19278.47191011 with a remaining 1.47e-07.
