We're dividing 22379859 by 145 
Let's see how many times 145 fits into 22379859.

On to step 1:
145 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 145

Moving on to step 2:
145 goes into 22 0 times with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 22 to get 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 145

Let's proceed to step 3:
The number 145 fits into 223 1 times, leaving a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 145 from 223, we get 78.
Bring next digit (7) of the dividend behind the 78 and repeat the process: 787 / 145

Advancing to step 4:
When dividing 787 by 145, we get 5 with a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 725 away from 787, we end up with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 145

Let's proceed to step 5:
The number 145 fits into 629 4 times, leaving a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 154.0
The remainder is 49 after subtracting 580 from 629.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 145

Step 6:
When dividing 498 by 145, we get 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 1543.0
If we subtract 435 from 498, we get 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 145

Step 7:
145 goes into 635 4 times with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 15434.0
Deduct 580 from 635 and we're left with 55.
Take the next digit (9) from the dividend and append it to 55, then repeat: 559 / 145

Step 8:
145 can be fit into 559 3 times, resulting in a remainder of 124.
The number 3 becomes the next digit in our result. 
Result so far: 154343.0
Subtract 435 from 559 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 9:
145 can be fit into 1240 8 times, resulting in a remainder of 80.
Use 8 as the next digit of our solution. 
Result so far: 154343.8
The remainder is 80 after subtracting 1160 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
When dividing 800 by 145, we get 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 154343.85
Subtract 725 from 800 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 11:
750 divided by 145 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 154343.855
Subtracting 725 from 750 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final outcome is 154343.855, with a leftover of 0.0025.
