If we divide 7 by 623, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 623

Step 2:
When dividing 77 by 623, we get 0 with a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 623

Advancing to step 3:
774 divided by 623 is 1 with a remainder of 151.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 623 from 774 to get 151.
Append the next digit (9) from the dividend to 151 and continue with: 1519 / 623

On to step 4:
When dividing 1519 by 623, we get 2 with a remainder of 273.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 1246 from 1519 and we're left with 273.
Grab the next digit (3) from the dividend, add it to 273, then carry on: 2733 / 623

Moving on to step 5:
623 goes into 2733 4 times with a remainder of 241.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
The remainder is 241 after subtracting 2492 from 2733.
Fetch the next digit (3) from the dividend, attach it to 241 and continue: 2413 / 623

Advancing to step 6:
If we divide 2413 by 623, we get 3 and a remainder of 544.
The next digit of our result is 3. 
Result so far: 1243.0
If we subtract 1869 from 2413, we get 544.
Include the next digit (9) from the dividend after 544, then repeat: 5449 / 623

On to step 7:
623 can be fit into 5449 8 times, resulting in a remainder of 465.
The number 8 becomes the next digit in our result. 
Result so far: 12438.0
If we subtract 4984 from 5449, we get 465.
Fetch the next digit (6) from the dividend, attach it to 465 and continue: 4656 / 623

Advancing to step 8:
4656 divided by 623 is 7 with a remainder of 295.
The next digit of our result is 7. 
Result so far: 124387.0
Deduct 4361 from 4656 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.

Advancing to step 9:
623 goes into 2950 4 times with a remainder of 458.
The number 4 becomes the next digit in our result. 
Result so far: 124387.4
Subtracting 2492 from 2950 leaves us with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 10:
623 can be fit into 4580 7 times, resulting in a remainder of 219.
Use 7 as the next digit of our solution. 
Result so far: 124387.47
Subtract 4361 from 4580 to get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

On to step 11:
2190 divided by 623 is 3 with a remainder of 321.
Write down 3 as next digit of the result. 
Result so far: 124387.473
The remainder is 321 after subtracting 1869 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Let's proceed to step 12:
If we divide 3210 by 623, we get 5 and a remainder of 95.
Record the quotient 5 as the next digit in the result. 
Result so far: 124387.4735
If we subtract 3115 from 3210, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 13:
If we divide 950 by 623, we get 1 and a remainder of 327.
Write down 1 as next digit of the result. 
Result so far: 124387.47351
Subtract 623 from 950 to get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 14:
If we divide 3270 by 623, we get 5 and a remainder of 155.
Record the quotient 5 as the next digit in the result. 
Result so far: 124387.473515
Subtract 3115 from 3270 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 15:
If we divide 1550 by 623, we get 2 and a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 124387.4735152
The remainder is 304 after subtracting 1246 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 16:
623 can be fit into 3040 4 times, resulting in a remainder of 548.
The number 4 becomes the next digit in our result. 
Result so far: 124387.47351524
Deduct 2492 from 3040 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

After the division, we end up with 124387.47351524 and a remainder of 5.48e-07.
