We're dividing 81489365 by 439 
Let's see how many times 439 fits into 81489365.

Let's proceed to step 1:
If we divide 8 by 439, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 439

Step 2:
81 divided by 439 is 0 with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 439

Advancing to step 3:
When dividing 814 by 439, we get 1 with a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 375 after subtracting 439 from 814.
Take the next digit (8) from the dividend and append it to 375, then repeat: 3758 / 439

Advancing to step 4:
When dividing 3758 by 439, we get 8 with a remainder of 246.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 3512 from 3758 leaves us with 246.
Grab the next digit (9) from the dividend, add it to 246, then carry on: 2469 / 439

On to step 5:
The number 439 fits into 2469 5 times, leaving a remainder of 274.
The number 5 becomes the next digit in our result. 
Result so far: 185.0
Subtract 2195 from 2469 to get 274.
Fetch the next digit (3) from the dividend, attach it to 274 and continue: 2743 / 439

On to step 6:
439 goes into 2743 6 times with a remainder of 109.
The number 6 becomes the next digit in our result. 
Result so far: 1856.0
Deduct 2634 from 2743 and we're left with 109.
Grab the next digit (6) from the dividend, add it to 109, then carry on: 1096 / 439

Let's proceed to step 7:
439 can be fit into 1096 2 times, resulting in a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 18562.0
Subtract 878 from 1096 to get 218.
Fetch the next digit (5) from the dividend, attach it to 218 and continue: 2185 / 439

Going ahead to step 8:
2185 divided by 439 is 4 with a remainder of 429.
Record the quotient 4 as the next digit in the result. 
Result so far: 185624.0
The remainder is 429 after subtracting 1756 from 2185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Step 9:
The number 439 fits into 4290 9 times, leaving a remainder of 339.
Record the quotient 9 as the next digit in the result. 
Result so far: 185624.9
If we take 3951 away from 4290, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 10:
When dividing 3390 by 439, we get 7 with a remainder of 317.
Write down 7 as next digit of the result. 
Result so far: 185624.97
Subtract 3073 from 3390 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 11:
3170 divided by 439 is 7 with a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 185624.977
The remainder is 97 after subtracting 3073 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

In conclusion, the division gives 185624.977 with a balance of 0.0097.
