We're dividing 81179772 by 437 
The aim is to understand the frequency of 437 in 81179772.

Advancing to step 1:
437 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 437

Going ahead to step 2:
When dividing 81 by 437, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (1) from the dividend after 81, then repeat: 811 / 437

Moving on to step 3:
If we divide 811 by 437, we get 1 and a remainder of 374.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 437 from 811 to get 374.
Fetch the next digit (7) from the dividend, attach it to 374 and continue: 3747 / 437

Step 4:
When dividing 3747 by 437, we get 8 with a remainder of 251.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 3496 from 3747, we get 251.
Fetch the next digit (9) from the dividend, attach it to 251 and continue: 2519 / 437

Step 5:
437 can be fit into 2519 5 times, resulting in a remainder of 334.
Put 5 as the next digit of the answer. 
Result so far: 185.0
The remainder is 334 after subtracting 2185 from 2519.
Include the next digit (7) from the dividend after 334, then repeat: 3347 / 437

Advancing to step 6:
When dividing 3347 by 437, we get 7 with a remainder of 288.
Record the quotient 7 as the next digit in the result. 
Result so far: 1857.0
If we take 3059 away from 3347, we end up with 288.
Grab the next digit (7) from the dividend, add it to 288, then carry on: 2887 / 437

Going ahead to step 7:
When dividing 2887 by 437, we get 6 with a remainder of 265.
Write down 6 as next digit of the result. 
Result so far: 18576.0
The remainder is 265 after subtracting 2622 from 2887.
Append the next digit (2) from the dividend to 265 and continue with: 2652 / 437

Advancing to step 8:
437 can be fit into 2652 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 185766.0
The remainder is 30 after subtracting 2622 from 2652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
437 can be fit into 300 0 times, resulting in a remainder of 300.
Write down 0 as next digit of the result. 
Result so far: 185766.0
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 10:
3000 divided by 437 is 6 with a remainder of 378.
Write down 6 as next digit of the result. 
Result so far: 185766.06
Subtracting 2622 from 3000 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 11:
3780 divided by 437 is 8 with a remainder of 284.
Put 8 as the next digit of the answer. 
Result so far: 185766.068
If we subtract 3496 from 3780, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 12:
437 can be fit into 2840 6 times, resulting in a remainder of 218.
The next digit of our result is 6. 
Result so far: 185766.0686
Subtract 2622 from 2840 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

On to step 13:
When dividing 2180 by 437, we get 4 with a remainder of 432.
Use 4 as the next digit of our solution. 
Result so far: 185766.06864
Subtract 1748 from 2180 to get 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 14:
437 goes into 4320 9 times with a remainder of 387.
Put 9 as the next digit of the answer. 
Result so far: 185766.068649
If we take 3933 away from 4320, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 15:
When dividing 3870 by 437, we get 8 with a remainder of 374.
The number 8 becomes the next digit in our result. 
Result so far: 185766.0686498
If we subtract 3496 from 3870, we 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.

On to step 16:
The number 437 fits into 3740 8 times, leaving a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 185766.06864988
If we subtract 3496 from 3740, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

After the division, we end up with 185766.06864988 and a remainder of 2.44e-07.
