Let's divide 143589 by 25
We want to divide 143589 by 25.

Moving on to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 25

On to step 2:
14 divided by 25 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 25

Advancing to step 3:
If we divide 143 by 25, we get 5 and a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 18 after subtracting 125 from 143.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 25

On to step 4:
When dividing 185 by 25, we get 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 57.0
The remainder is 10 after subtracting 175 from 185.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 25

On to step 5:
When dividing 108 by 25, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 574.0
If we take 100 away from 108, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 25

Advancing to step 6:
25 goes into 89 3 times with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 5743.0
Deduct 75 from 89 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 25 fits into 140 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 5743.5
Deduct 125 from 140 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
When dividing 150 by 25, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 5743.56
Subtracting 150 from 150 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5743.56
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5743.56
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5743.56, with a leftover of 0.0.
