Let's divide 81905836 by 507
We're looking to find how many times 507 goes into 81905836.

Let's proceed to step 1:
The number 507 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
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 / 507

Advancing to step 2:
If we divide 81 by 507, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 507

Advancing to step 3:
507 can be fit into 819 1 times, resulting in a remainder of 312.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 507 from 819 leaves us with 312.
Fetch the next digit (0) from the dividend, attach it to 312 and continue: 3120 / 507

On to step 4:
507 can be fit into 3120 6 times, resulting in a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3042 from 3120, we get 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 507

Moving on to step 5:
If we divide 785 by 507, we get 1 and a remainder of 278.
Write down 1 as next digit of the result. 
Result so far: 161.0
Deduct 507 from 785 and we're left with 278.
Include the next digit (8) from the dividend after 278, then repeat: 2788 / 507

Going ahead to step 6:
The number 507 fits into 2788 5 times, leaving a remainder of 253.
Record the quotient 5 as the next digit in the result. 
Result so far: 1615.0
If we subtract 2535 from 2788, we get 253.
Grab the next digit (3) from the dividend, add it to 253, then carry on: 2533 / 507

Going ahead to step 7:
507 can be fit into 2533 4 times, resulting in a remainder of 505.
Write down 4 as next digit of the result. 
Result so far: 16154.0
The remainder is 505 after subtracting 2028 from 2533.
Bring next digit (6) of the dividend behind the 505 and repeat the process: 5056 / 507

Let's proceed to step 8:
If we divide 5056 by 507, we get 9 and a remainder of 493.
Record the quotient 9 as the next digit in the result. 
Result so far: 161549.0
The remainder is 493 after subtracting 4563 from 5056.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4930, and continue the process.

Going ahead to step 9:
507 can be fit into 4930 9 times, resulting in a remainder of 367.
The number 9 becomes the next digit in our result. 
Result so far: 161549.9
The remainder is 367 after subtracting 4563 from 4930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 10:
507 goes into 3670 7 times with a remainder of 121.
The next digit of our result is 7. 
Result so far: 161549.97
Deduct 3549 from 3670 and we're left with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 11:
The number 507 fits into 1210 2 times, leaving a remainder of 196.
The number 2 becomes the next digit in our result. 
Result so far: 161549.972
Subtract 1014 from 1210 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 12:
507 goes into 1960 3 times with a remainder of 439.
Record the quotient 3 as the next digit in the result. 
Result so far: 161549.9723
Deduct 1521 from 1960 and we're left with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Let's proceed to step 13:
The number 507 fits into 4390 8 times, leaving a remainder of 334.
Put 8 as the next digit of the answer. 
Result so far: 161549.97238
The remainder is 334 after subtracting 4056 from 4390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 14:
When dividing 3340 by 507, we get 6 with a remainder of 298.
The number 6 becomes the next digit in our result. 
Result so far: 161549.972386
If we take 3042 away from 3340, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 15:
When dividing 2980 by 507, we get 5 with a remainder of 445.
Write down 5 as next digit of the result. 
Result so far: 161549.9723865
Subtract 2535 from 2980 to get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Advancing to step 16:
The number 507 fits into 4450 8 times, leaving a remainder of 394.
The next digit of our result is 8. 
Result so far: 161549.97238658
Subtracting 4056 from 4450 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

The final result is 161549.97238658 with a remainder of 3.94e-07.
