Let's divide 81307639 by 434
We're looking to find how many times 434 goes into 81307639.

Going ahead to step 1:
If we divide 8 by 434, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 434

Going ahead to step 2:
When dividing 81 by 434, we get 0 with a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 434

On to step 3:
The number 434 fits into 813 1 times, leaving a remainder of 379.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 434 from 813, we get 379.
Fetch the next digit (0) from the dividend, attach it to 379 and continue: 3790 / 434

Let's proceed to step 4:
If we divide 3790 by 434, we get 8 and a remainder of 318.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 3472 from 3790 and we're left with 318.
Bring next digit (7) of the dividend behind the 318 and repeat the process: 3187 / 434

Let's proceed to step 5:
The number 434 fits into 3187 7 times, leaving a remainder of 149.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Deduct 3038 from 3187 and we're left with 149.
Bring next digit (6) of the dividend behind the 149 and repeat the process: 1496 / 434

Moving on to step 6:
When dividing 1496 by 434, we get 3 with a remainder of 194.
Put 3 as the next digit of the answer. 
Result so far: 1873.0
Deduct 1302 from 1496 and we're left with 194.
Include the next digit (3) from the dividend after 194, then repeat: 1943 / 434

Moving on to step 7:
When dividing 1943 by 434, we get 4 with a remainder of 207.
Record the quotient 4 as the next digit in the result. 
Result so far: 18734.0
Subtracting 1736 from 1943 leaves us with 207.
Bring next digit (9) of the dividend behind the 207 and repeat the process: 2079 / 434

On to step 8:
434 can be fit into 2079 4 times, resulting in a remainder of 343.
Use 4 as the next digit of our solution. 
Result so far: 187344.0
Subtracting 1736 from 2079 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Moving on to step 9:
3430 divided by 434 is 7 with a remainder of 392.
Record the quotient 7 as the next digit in the result. 
Result so far: 187344.7
Subtract 3038 from 3430 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
434 goes into 3920 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 187344.79
The remainder is 14 after subtracting 3906 from 3920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
If we divide 140 by 434, we get 0 and a remainder of 140.
Record the quotient 0 as the next digit in the result. 
Result so far: 187344.79
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
434 goes into 1400 3 times with a remainder of 98.
The next digit of our result is 3. 
Result so far: 187344.7903
Subtract 1302 from 1400 to get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 13:
When dividing 980 by 434, we get 2 with a remainder of 112.
The number 2 becomes the next digit in our result. 
Result so far: 187344.79032
Deduct 868 from 980 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 14:
The number 434 fits into 1120 2 times, leaving a remainder of 252.
Put 2 as the next digit of the answer. 
Result so far: 187344.790322
If we take 868 away from 1120, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The quotient of the division is 187344.790322, and the remainder is 2.52e-05.
