81671682 ÷ 284 
The aim is to understand the frequency of 284 in 81671682.

Let's proceed to step 1:
8 divided by 284 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 284

Step 2:
When dividing 81 by 284, we get 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 284

Advancing to step 3:
If we divide 816 by 284, we get 2 and a remainder of 248.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 248 after subtracting 568 from 816.
Append the next digit (7) from the dividend to 248 and continue with: 2487 / 284

On to step 4:
284 can be fit into 2487 8 times, resulting in a remainder of 215.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 2272 away from 2487, we end up with 215.
Include the next digit (1) from the dividend after 215, then repeat: 2151 / 284

Going ahead to step 5:
When dividing 2151 by 284, we get 7 with a remainder of 163.
The number 7 becomes the next digit in our result. 
Result so far: 287.0
Subtracting 1988 from 2151 leaves us with 163.
Append the next digit (6) from the dividend to 163 and continue with: 1636 / 284

Going ahead to step 6:
284 goes into 1636 5 times with a remainder of 216.
Use 5 as the next digit of our solution. 
Result so far: 2875.0
The remainder is 216 after subtracting 1420 from 1636.
Append the next digit (8) from the dividend to 216 and continue with: 2168 / 284

Going ahead to step 7:
When dividing 2168 by 284, we get 7 with a remainder of 180.
Use 7 as the next digit of our solution. 
Result so far: 28757.0
If we take 1988 away from 2168, we end up with 180.
Take the next digit (2) from the dividend and append it to 180, then repeat: 1802 / 284

Advancing to step 8:
The number 284 fits into 1802 6 times, leaving a remainder of 98.
Write down 6 as next digit of the result. 
Result so far: 287576.0
Deduct 1704 from 1802 and we're left 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 9:
284 goes into 980 3 times with a remainder of 128.
The next digit of our result is 3. 
Result so far: 287576.3
Deduct 852 from 980 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 10:
1280 divided by 284 is 4 with a remainder of 144.
The number 4 becomes the next digit in our result. 
Result so far: 287576.34
Subtracting 1136 from 1280 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 11:
When dividing 1440 by 284, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 287576.345
The remainder is 20 after subtracting 1420 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
When dividing 200 by 284, we get 0 with a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 287576.345
If we take 0 away from 200, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
If we divide 2000 by 284, we get 7 and a remainder of 12.
The next digit of our result is 7. 
Result so far: 287576.34507
If we subtract 1988 from 2000, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
284 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 287576.34507
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
The number 284 fits into 1200 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 287576.3450704
If we take 1136 away from 1200, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
The number 284 fits into 640 2 times, leaving a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 287576.34507042
Deduct 568 from 640 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 287576.34507042, with a leftover of 7.2e-08.
