85054565 divided by 280 
The aim is to understand the frequency of 280 in 85054565.

On to step 1:
280 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
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 280

Moving on to step 2:
When dividing 85 by 280, we get 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (0) from the dividend, add it to 85, then carry on: 850 / 280

On to step 3:
The number 280 fits into 850 3 times, leaving a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 840 from 850 and we're left with 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 280

Advancing to step 4:
The number 280 fits into 105 0 times, leaving a remainder of 105.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 105 after subtracting 0 from 105.
Include the next digit (4) from the dividend after 105, then repeat: 1054 / 280

On to step 5:
When dividing 1054 by 280, we get 3 with a remainder of 214.
Put 3 as the next digit of the answer. 
Result so far: 303.0
Subtracting 840 from 1054 leaves us with 214.
Fetch the next digit (5) from the dividend, attach it to 214 and continue: 2145 / 280

Step 6:
280 can be fit into 2145 7 times, resulting in a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 3037.0
Subtract 1960 from 2145 to get 185.
Append the next digit (6) from the dividend to 185 and continue with: 1856 / 280

Advancing to step 7:
1856 divided by 280 is 6 with a remainder of 176.
Put 6 as the next digit of the answer. 
Result so far: 30376.0
Subtract 1680 from 1856 to get 176.
Append the next digit (5) from the dividend to 176 and continue with: 1765 / 280

Advancing to step 8:
280 can be fit into 1765 6 times, resulting in a remainder of 85.
Write down 6 as next digit of the result. 
Result so far: 303766.0
Deduct 1680 from 1765 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
When dividing 850 by 280, we get 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 303766.3
The remainder is 10 after subtracting 840 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 280 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 303766.3
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 11:
280 goes into 1000 3 times with a remainder of 160.
Use 3 as the next digit of our solution. 
Result so far: 303766.303
If we take 840 away from 1000, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
If we divide 1600 by 280, we get 5 and a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 303766.3035
Deduct 1400 from 1600 and we're left 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:
When dividing 2000 by 280, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 303766.30357
If we subtract 1960 from 2000, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
280 can be fit into 400 1 times, resulting in a remainder of 120.
Record the quotient 1 as the next digit in the result. 
Result so far: 303766.303571
If we subtract 280 from 400, 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.

On to step 15:
280 goes into 1200 4 times with a remainder of 80.
The number 4 becomes the next digit in our result. 
Result so far: 303766.3035714
Subtracting 1120 from 1200 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
280 can be fit into 800 2 times, resulting in a remainder of 240.
The next digit of our result is 2. 
Result so far: 303766.30357142
Subtracting 560 from 800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final outcome is 303766.30357142, with a leftover of 2.4e-07.
