We look at the division of 81523087 by 609 
We're looking to find how many times 609 goes into 81523087.

Step 1:
8 divided by 609 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 609

Going ahead to step 2:
When dividing 81 by 609, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 609

Moving on to step 3:
815 divided by 609 is 1 with a remainder of 206.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 609 from 815, we get 206.
Fetch the next digit (2) from the dividend, attach it to 206 and continue: 2062 / 609

On to step 4:
609 can be fit into 2062 3 times, resulting in a remainder of 235.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 1827 away from 2062, we end up with 235.
Grab the next digit (3) from the dividend, add it to 235, then carry on: 2353 / 609

Step 5:
If we divide 2353 by 609, we get 3 and a remainder of 526.
The next digit of our result is 3. 
Result so far: 133.0
The remainder is 526 after subtracting 1827 from 2353.
Include the next digit (0) from the dividend after 526, then repeat: 5260 / 609

Let's proceed to step 6:
609 can be fit into 5260 8 times, resulting in a remainder of 388.
Record the quotient 8 as the next digit in the result. 
Result so far: 1338.0
If we subtract 4872 from 5260, we get 388.
Take the next digit (8) from the dividend and append it to 388, then repeat: 3888 / 609

Advancing to step 7:
609 goes into 3888 6 times with a remainder of 234.
The next digit of our result is 6. 
Result so far: 13386.0
The remainder is 234 after subtracting 3654 from 3888.
Take the next digit (7) from the dividend and append it to 234, then repeat: 2347 / 609

Moving on to step 8:
When dividing 2347 by 609, we get 3 with a remainder of 520.
The number 3 becomes the next digit in our result. 
Result so far: 133863.0
If we take 1827 away from 2347, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 9:
If we divide 5200 by 609, we get 8 and a remainder of 328.
The next digit of our result is 8. 
Result so far: 133863.8
Subtracting 4872 from 5200 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Moving on to step 10:
3280 divided by 609 is 5 with a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 133863.85
Subtract 3045 from 3280 to get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Let's proceed to step 11:
2350 divided by 609 is 3 with a remainder of 523.
Use 3 as the next digit of our solution. 
Result so far: 133863.853
If we take 1827 away from 2350, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 12:
When dividing 5230 by 609, we get 8 with a remainder of 358.
Use 8 as the next digit of our solution. 
Result so far: 133863.8538
If we take 4872 away from 5230, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 13:
The number 609 fits into 3580 5 times, leaving a remainder of 535.
Record the quotient 5 as the next digit in the result. 
Result so far: 133863.85385
Subtracting 3045 from 3580 leaves us with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Let's proceed to step 14:
When dividing 5350 by 609, we get 8 with a remainder of 478.
Use 8 as the next digit of our solution. 
Result so far: 133863.853858
If we subtract 4872 from 5350, we get 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Step 15:
The number 609 fits into 4780 7 times, leaving a remainder of 517.
The next digit of our result is 7. 
Result so far: 133863.8538587
Deduct 4263 from 4780 and we're left with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Let's proceed to step 16:
When dividing 5170 by 609, we get 8 with a remainder of 298.
Record the quotient 8 as the next digit in the result. 
Result so far: 133863.85385878
The remainder is 298 after subtracting 4872 from 5170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

In conclusion, the division gives 133863.85385878 with a balance of 2.98e-07.
