We're dividing 22154389 by 723 
We want to figure out the number of times 22154389 can be divided by 723.

Going ahead to step 1:
If we divide 2 by 723, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 723

Let's proceed to step 2:
723 goes into 22 0 times with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 723

Advancing to step 3:
221 divided by 723 is 0 with a remainder of 221.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 221 to get 221.
Grab the next digit (5) from the dividend, add it to 221, then carry on: 2215 / 723

On to step 4:
723 can be fit into 2215 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 46 after subtracting 2169 from 2215.
Fetch the next digit (4) from the dividend, attach it to 46 and continue: 464 / 723

On to step 5:
If we divide 464 by 723, we get 0 and a remainder of 464.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 464 after subtracting 0 from 464.
Bring next digit (3) of the dividend behind the 464 and repeat the process: 4643 / 723

On to step 6:
4643 divided by 723 is 6 with a remainder of 305.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
If we subtract 4338 from 4643, we get 305.
Bring next digit (8) of the dividend behind the 305 and repeat the process: 3058 / 723

Step 7:
3058 divided by 723 is 4 with a remainder of 166.
The next digit of our result is 4. 
Result so far: 3064.0
If we take 2892 away from 3058, we end up with 166.
Take the next digit (9) from the dividend and append it to 166, then repeat: 1669 / 723

Going ahead to step 8:
When dividing 1669 by 723, we get 2 with a remainder of 223.
The number 2 becomes the next digit in our result. 
Result so far: 30642.0
If we take 1446 away from 1669, we end up with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 9:
723 goes into 2230 3 times with a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 30642.3
Subtract 2169 from 2230 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 10:
The number 723 fits into 610 0 times, leaving a remainder of 610.
The next digit of our result is 0. 
Result so far: 30642.3
The remainder is 610 after subtracting 0 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 11:
When dividing 6100 by 723, we get 8 with a remainder of 316.
Write down 8 as next digit of the result. 
Result so far: 30642.308
If we subtract 5784 from 6100, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 12:
723 goes into 3160 4 times with a remainder of 268.
Write down 4 as next digit of the result. 
Result so far: 30642.3084
Subtract 2892 from 3160 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 13:
2680 divided by 723 is 3 with a remainder of 511.
Put 3 as the next digit of the answer. 
Result so far: 30642.30843
Subtracting 2169 from 2680 leaves us with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

Moving on to step 14:
If we divide 5110 by 723, we get 7 and a remainder of 49.
Write down 7 as next digit of the result. 
Result so far: 30642.308437
If we take 5061 away from 5110, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 15:
723 goes into 490 0 times with a remainder of 490.
Put 0 as the next digit of the answer. 
Result so far: 30642.308437
Deduct 0 from 490 and we're left with 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

Let's proceed to step 16:
If we divide 4900 by 723, we get 6 and a remainder of 562.
Put 6 as the next digit of the answer. 
Result so far: 30642.30843706
If we subtract 4338 from 4900, we get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

The final outcome is 30642.30843706, with a leftover of 5.62e-07.
