We divide 13815719 by 623
We want to figure out the number of times 13815719 can be divided by 623.

Let's proceed to step 1:
When dividing 1 by 623, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 623

On to step 2:
If we divide 13 by 623, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 623

Moving on to step 3:
138 divided by 623 is 0 with a remainder of 138.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 138 after subtracting 0 from 138.
Grab the next digit (1) from the dividend, add it to 138, then carry on: 1381 / 623

Going ahead to step 4:
If we divide 1381 by 623, we get 2 and a remainder of 135.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1246 from 1381 leaves us with 135.
Take the next digit (5) from the dividend and append it to 135, then repeat: 1355 / 623

Moving on to step 5:
623 can be fit into 1355 2 times, resulting in a remainder of 109.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 1246 away from 1355, we end up with 109.
Take the next digit (7) from the dividend and append it to 109, then repeat: 1097 / 623

On to step 6:
The number 623 fits into 1097 1 times, leaving a remainder of 474.
The number 1 becomes the next digit in our result. 
Result so far: 221.0
Deduct 623 from 1097 and we're left with 474.
Append the next digit (1) from the dividend to 474 and continue with: 4741 / 623

Let's proceed to step 7:
If we divide 4741 by 623, we get 7 and a remainder of 380.
Put 7 as the next digit of the answer. 
Result so far: 2217.0
Subtract 4361 from 4741 to get 380.
Include the next digit (9) from the dividend after 380, then repeat: 3809 / 623

Advancing to step 8:
623 goes into 3809 6 times with a remainder of 71.
The number 6 becomes the next digit in our result. 
Result so far: 22176.0
If we take 3738 away from 3809, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 9:
The number 623 fits into 710 1 times, leaving a remainder of 87.
Use 1 as the next digit of our solution. 
Result so far: 22176.1
If we take 623 away from 710, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 10:
If we divide 870 by 623, we get 1 and a remainder of 247.
The next digit of our result is 1. 
Result so far: 22176.11
If we subtract 623 from 870, we get 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

In conclusion, the division gives 22176.11 with a balance of 0.247.
