We're dividing 81781774 by 514 
The aim is to understand the frequency of 514 in 81781774.

Advancing to step 1:
514 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 514

Let's proceed to step 2:
514 goes into 81 0 times with a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 514

Moving on to step 3:
When dividing 817 by 514, we get 1 with a remainder of 303.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 514 from 817 and we're left with 303.
Bring next digit (8) of the dividend behind the 303 and repeat the process: 3038 / 514

Moving on to step 4:
3038 divided by 514 is 5 with a remainder of 468.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 2570 from 3038, we get 468.
Take the next digit (1) from the dividend and append it to 468, then repeat: 4681 / 514

Moving on to step 5:
514 goes into 4681 9 times with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 159.0
The remainder is 55 after subtracting 4626 from 4681.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 514

On to step 6:
When dividing 557 by 514, we get 1 with a remainder of 43.
The next digit of our result is 1. 
Result so far: 1591.0
Subtract 514 from 557 to get 43.
Fetch the next digit (7) from the dividend, attach it to 43 and continue: 437 / 514

Advancing to step 7:
The number 514 fits into 437 0 times, leaving a remainder of 437.
Write down 0 as next digit of the result. 
Result so far: 15910.0
The remainder is 437 after subtracting 0 from 437.
Bring next digit (4) of the dividend behind the 437 and repeat the process: 4374 / 514

Let's proceed to step 8:
514 can be fit into 4374 8 times, resulting in a remainder of 262.
The next digit of our result is 8. 
Result so far: 159108.0
Subtract 4112 from 4374 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

On to step 9:
514 can be fit into 2620 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 159108.5
If we take 2570 away from 2620, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
When dividing 500 by 514, we get 0 with a remainder of 500.
The next digit of our result is 0. 
Result so far: 159108.5
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 11:
514 can be fit into 5000 9 times, resulting in a remainder of 374.
The next digit of our result is 9. 
Result so far: 159108.509
Subtract 4626 from 5000 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Moving on to step 12:
The number 514 fits into 3740 7 times, leaving a remainder of 142.
The next digit of our result is 7. 
Result so far: 159108.5097
If we subtract 3598 from 3740, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

On to step 13:
When dividing 1420 by 514, we get 2 with a remainder of 392.
Put 2 as the next digit of the answer. 
Result so far: 159108.50972
Subtracting 1028 from 1420 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 14:
514 can be fit into 3920 7 times, resulting in a remainder of 322.
The next digit of our result is 7. 
Result so far: 159108.509727
Subtracting 3598 from 3920 leaves us with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Advancing to step 15:
If we divide 3220 by 514, we get 6 and a remainder of 136.
Use 6 as the next digit of our solution. 
Result so far: 159108.5097276
Deduct 3084 from 3220 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 16:
1360 divided by 514 is 2 with a remainder of 332.
Use 2 as the next digit of our solution. 
Result so far: 159108.50972762
If we subtract 1028 from 1360, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Our division results in 159108.50972762 with a remaining 3.32e-07.
