We look at the division of 3111393 by 623 
We want to figure out the number of times 3111393 can be divided by 623.

Advancing to step 1:
If we divide 3 by 623, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 623

Step 2:
623 can be fit into 31 0 times, resulting in a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 623

Going ahead to step 3:
311 divided by 623 is 0 with a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 311 to get 311.
Bring next digit (1) of the dividend behind the 311 and repeat the process: 3111 / 623

Going ahead to step 4:
3111 divided by 623 is 4 with a remainder of 619.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2492 from 3111 leaves us with 619.
Bring next digit (3) of the dividend behind the 619 and repeat the process: 6193 / 623

Step 5:
623 can be fit into 6193 9 times, resulting in a remainder of 586.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtracting 5607 from 6193 leaves us with 586.
Bring next digit (9) of the dividend behind the 586 and repeat the process: 5869 / 623

Let's proceed to step 6:
If we divide 5869 by 623, we get 9 and a remainder of 262.
Write down 9 as next digit of the result. 
Result so far: 499.0
Subtracting 5607 from 5869 leaves us with 262.
Append the next digit (3) from the dividend to 262 and continue with: 2623 / 623

Step 7:
623 goes into 2623 4 times with a remainder of 131.
Record the quotient 4 as the next digit in the result. 
Result so far: 4994.0
If we subtract 2492 from 2623, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 8:
1310 divided by 623 is 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 4994.2
If we take 1246 away from 1310, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
The number 623 fits into 640 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 4994.21
If we take 623 away from 640, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
623 goes into 170 0 times with a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 4994.21
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 11:
When dividing 1700 by 623, we get 2 with a remainder of 454.
Record the quotient 2 as the next digit in the result. 
Result so far: 4994.2102
Subtracting 1246 from 1700 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 12:
If we divide 4540 by 623, we get 7 and a remainder of 179.
The next digit of our result is 7. 
Result so far: 4994.21027
Subtracting 4361 from 4540 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 13:
623 can be fit into 1790 2 times, resulting in a remainder of 544.
The number 2 becomes the next digit in our result. 
Result so far: 4994.210272
Subtract 1246 from 1790 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 14:
5440 divided by 623 is 8 with a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 4994.2102728
Deduct 4984 from 5440 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Moving on to step 15:
When dividing 4560 by 623, we get 7 with a remainder of 199.
The number 7 becomes the next digit in our result. 
Result so far: 4994.21027287
Deduct 4361 from 4560 and we're left with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 4994.21027287 and a remainder of 1.99e-07.
