We divide 81955231 by 509
We want to figure out the number of times 81955231 can be divided by 509.

Going ahead to step 1:
When dividing 8 by 509, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 509

Let's proceed to step 2:
If we divide 81 by 509, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (9) from the dividend, attach it to 81 and continue: 819 / 509

Let's proceed to step 3:
When dividing 819 by 509, we get 1 with a remainder of 310.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 310 after subtracting 509 from 819.
Grab the next digit (5) from the dividend, add it to 310, then carry on: 3105 / 509

Let's proceed to step 4:
509 goes into 3105 6 times with a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 3054 from 3105 leaves us with 51.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 509

Going ahead to step 5:
509 goes into 515 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
Subtracting 509 from 515 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 509

Moving on to step 6:
When dividing 62 by 509, we get 0 with a remainder of 62.
Write down 0 as next digit of the result. 
Result so far: 1610.0
The remainder is 62 after subtracting 0 from 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 509

Moving on to step 7:
The number 509 fits into 623 1 times, leaving a remainder of 114.
Write down 1 as next digit of the result. 
Result so far: 16101.0
If we subtract 509 from 623, we get 114.
Bring next digit (1) of the dividend behind the 114 and repeat the process: 1141 / 509

Let's proceed to step 8:
509 goes into 1141 2 times with a remainder of 123.
Use 2 as the next digit of our solution. 
Result so far: 161012.0
The remainder is 123 after subtracting 1018 from 1141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Step 9:
If we divide 1230 by 509, we get 2 and a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 161012.2
If we take 1018 away from 1230, we end up with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 10:
The number 509 fits into 2120 4 times, leaving a remainder of 84.
Use 4 as the next digit of our solution. 
Result so far: 161012.24
If we subtract 2036 from 2120, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 11:
509 can be fit into 840 1 times, resulting in a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 161012.241
The remainder is 331 after subtracting 509 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 12:
If we divide 3310 by 509, we get 6 and a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 161012.2416
If we subtract 3054 from 3310, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 13:
509 goes into 2560 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 161012.24165
If we subtract 2545 from 2560, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 14:
The number 509 fits into 150 0 times, leaving a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 161012.24165
Deduct 0 from 150 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 15:
When dividing 1500 by 509, we get 2 with a remainder of 482.
Write down 2 as next digit of the result. 
Result so far: 161012.2416502
If we take 1018 away from 1500, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 16:
509 can be fit into 4820 9 times, resulting in a remainder of 239.
Record the quotient 9 as the next digit in the result. 
Result so far: 161012.24165029
If we subtract 4581 from 4820, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

In conclusion, the division gives 161012.24165029 with a balance of 2.39e-07.
