We look at the division of 93173569 by 623 
We want to figure out the number of times 93173569 can be divided by 623.

On to step 1:
If we divide 9 by 623, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 623

On to step 2:
623 goes into 93 0 times with a remainder of 93.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 93 to get 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 623

Let's proceed to step 3:
If we divide 931 by 623, we get 1 and a remainder of 308.
The next digit of our result is 1. 
Result so far: 1.0
If we take 623 away from 931, we end up with 308.
Include the next digit (7) from the dividend after 308, then repeat: 3087 / 623

Let's proceed to step 4:
623 can be fit into 3087 4 times, resulting in a remainder of 595.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2492 from 3087, we get 595.
Include the next digit (3) from the dividend after 595, then repeat: 5953 / 623

Going ahead to step 5:
The number 623 fits into 5953 9 times, leaving a remainder of 346.
Write down 9 as next digit of the result. 
Result so far: 149.0
Deduct 5607 from 5953 and we're left with 346.
Grab the next digit (5) from the dividend, add it to 346, then carry on: 3465 / 623

Going ahead to step 6:
623 can be fit into 3465 5 times, resulting in a remainder of 350.
Put 5 as the next digit of the answer. 
Result so far: 1495.0
If we subtract 3115 from 3465, we get 350.
Grab the next digit (6) from the dividend, add it to 350, then carry on: 3506 / 623

Going ahead to step 7:
The number 623 fits into 3506 5 times, leaving a remainder of 391.
The next digit of our result is 5. 
Result so far: 14955.0
The remainder is 391 after subtracting 3115 from 3506.
Append the next digit (9) from the dividend to 391 and continue with: 3919 / 623

Advancing to step 8:
3919 divided by 623 is 6 with a remainder of 181.
The next digit of our result is 6. 
Result so far: 149556.0
Deduct 3738 from 3919 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 9:
623 goes into 1810 2 times with a remainder of 564.
Write down 2 as next digit of the result. 
Result so far: 149556.2
Subtract 1246 from 1810 to get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Going ahead to step 10:
If we divide 5640 by 623, we get 9 and a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 149556.29
If we take 5607 away from 5640, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 11:
The number 623 fits into 330 0 times, leaving a remainder of 330.
Write down 0 as next digit of the result. 
Result so far: 149556.29
Subtracting 0 from 330 leaves us with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 12:
If we divide 3300 by 623, we get 5 and a remainder of 185.
Record the quotient 5 as the next digit in the result. 
Result so far: 149556.2905
If we subtract 3115 from 3300, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 13:
The number 623 fits into 1850 2 times, leaving a remainder of 604.
Put 2 as the next digit of the answer. 
Result so far: 149556.29052
Subtract 1246 from 1850 to get 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Moving on to step 14:
623 can be fit into 6040 9 times, resulting in a remainder of 433.
Record the quotient 9 as the next digit in the result. 
Result so far: 149556.290529
The remainder is 433 after subtracting 5607 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Moving on to step 15:
When dividing 4330 by 623, we get 6 with a remainder of 592.
Use 6 as the next digit of our solution. 
Result so far: 149556.2905296
Deduct 3738 from 4330 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 16:
When dividing 5920 by 623, we get 9 with a remainder of 313.
Write down 9 as next digit of the result. 
Result so far: 149556.29052969
If we subtract 5607 from 5920, we get 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

The final outcome is 149556.29052969, with a leftover of 3.13e-07.
