81116207 ÷ 507 
The aim is to understand the frequency of 507 in 81116207.

Going ahead to step 1:
8 divided by 507 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 507

Let's proceed to step 2:
507 goes into 81 0 times with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 507

Going ahead to step 3:
When dividing 811 by 507, we get 1 with a remainder of 304.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 507 from 811 to get 304.
Include the next digit (1) from the dividend after 304, then repeat: 3041 / 507

Moving on to step 4:
If we divide 3041 by 507, we get 5 and a remainder of 506.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 2535 from 3041, we get 506.
Take the next digit (6) from the dividend and append it to 506, then repeat: 5066 / 507

Moving on to step 5:
If we divide 5066 by 507, we get 9 and a remainder of 503.
Write down 9 as next digit of the result. 
Result so far: 159.0
Subtract 4563 from 5066 to get 503.
Append the next digit (2) from the dividend to 503 and continue with: 5032 / 507

Moving on to step 6:
When dividing 5032 by 507, we get 9 with a remainder of 469.
Use 9 as the next digit of our solution. 
Result so far: 1599.0
Subtracting 4563 from 5032 leaves us with 469.
Take the next digit (0) from the dividend and append it to 469, then repeat: 4690 / 507

Let's proceed to step 7:
4690 divided by 507 is 9 with a remainder of 127.
The next digit of our result is 9. 
Result so far: 15999.0
If we subtract 4563 from 4690, we get 127.
Include the next digit (7) from the dividend after 127, then repeat: 1277 / 507

Moving on to step 8:
507 goes into 1277 2 times with a remainder of 263.
Record the quotient 2 as the next digit in the result. 
Result so far: 159992.0
Deduct 1014 from 1277 and we're left with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 9:
When dividing 2630 by 507, we get 5 with a remainder of 95.
The number 5 becomes the next digit in our result. 
Result so far: 159992.5
Subtracting 2535 from 2630 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 10:
507 goes into 950 1 times with a remainder of 443.
The next digit of our result is 1. 
Result so far: 159992.51
Deduct 507 from 950 and we're left with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

Advancing to step 11:
When dividing 4430 by 507, we get 8 with a remainder of 374.
Use 8 as the next digit of our solution. 
Result so far: 159992.518
Subtracting 4056 from 4430 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Going ahead to step 12:
If we divide 3740 by 507, we get 7 and a remainder of 191.
The number 7 becomes the next digit in our result. 
Result so far: 159992.5187
The remainder is 191 after subtracting 3549 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Moving on to step 13:
When dividing 1910 by 507, we get 3 with a remainder of 389.
The next digit of our result is 3. 
Result so far: 159992.51873
Subtracting 1521 from 1910 leaves us with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 14:
If we divide 3890 by 507, we get 7 and a remainder of 341.
Record the quotient 7 as the next digit in the result. 
Result so far: 159992.518737
Subtract 3549 from 3890 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 15:
If we divide 3410 by 507, we get 6 and a remainder of 368.
Record the quotient 6 as the next digit in the result. 
Result so far: 159992.5187376
If we take 3042 away from 3410, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 16:
When dividing 3680 by 507, we get 7 with a remainder of 131.
Write down 7 as next digit of the result. 
Result so far: 159992.51873767
Subtract 3549 from 3680 to get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The final outcome is 159992.51873767, with a leftover of 1.31e-07.
