89280683 ÷ 437 
The aim is to understand the frequency of 437 in 89280683.

Step 1:
If we divide 8 by 437, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 437

Going ahead to step 2:
The number 437 fits into 89 0 times, leaving a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Append the next digit (2) from the dividend to 89 and continue with: 892 / 437

Moving on to step 3:
437 goes into 892 2 times with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 18 after subtracting 874 from 892.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 437

On to step 4:
If we divide 188 by 437, we get 0 and a remainder of 188.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 188, we end up with 188.
Append the next digit (0) from the dividend to 188 and continue with: 1880 / 437

Going ahead to step 5:
If we divide 1880 by 437, we get 4 and a remainder of 132.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Deduct 1748 from 1880 and we're left with 132.
Include the next digit (6) from the dividend after 132, then repeat: 1326 / 437

Going ahead to step 6:
If we divide 1326 by 437, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 2043.0
The remainder is 15 after subtracting 1311 from 1326.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 437

Advancing to step 7:
158 divided by 437 is 0 with a remainder of 158.
Put 0 as the next digit of the answer. 
Result so far: 20430.0
The remainder is 158 after subtracting 0 from 158.
Append the next digit (3) from the dividend to 158 and continue with: 1583 / 437

Moving on to step 8:
The number 437 fits into 1583 3 times, leaving a remainder of 272.
Record the quotient 3 as the next digit in the result. 
Result so far: 204303.0
The remainder is 272 after subtracting 1311 from 1583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Step 9:
2720 divided by 437 is 6 with a remainder of 98.
The number 6 becomes the next digit in our result. 
Result so far: 204303.6
If we take 2622 away from 2720, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 10:
437 goes into 980 2 times with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 204303.62
If we subtract 874 from 980, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 11:
437 goes into 1060 2 times with a remainder of 186.
Write down 2 as next digit of the result. 
Result so far: 204303.622
The remainder is 186 after subtracting 874 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The final result is 204303.622 with a remainder of 0.0186.
