We're dividing 87908626 by 280 
The aim is to understand the frequency of 280 in 87908626.

Let's proceed to step 1:
If we divide 8 by 280, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 280

Moving on to step 2:
When dividing 87 by 280, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 280

Going ahead to step 3:
When dividing 879 by 280, we get 3 with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 840 from 879 and we're left with 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 280

On to step 4:
280 goes into 390 1 times with a remainder of 110.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 280 from 390 to get 110.
Take the next digit (8) from the dividend and append it to 110, then repeat: 1108 / 280

Step 5:
If we divide 1108 by 280, we get 3 and a remainder of 268.
The next digit of our result is 3. 
Result so far: 313.0
Subtract 840 from 1108 to get 268.
Grab the next digit (6) from the dividend, add it to 268, then carry on: 2686 / 280

Advancing to step 6:
2686 divided by 280 is 9 with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 3139.0
If we take 2520 away from 2686, we end up with 166.
Append the next digit (2) from the dividend to 166 and continue with: 1662 / 280

Step 7:
The number 280 fits into 1662 5 times, leaving a remainder of 262.
Record the quotient 5 as the next digit in the result. 
Result so far: 31395.0
Deduct 1400 from 1662 and we're left with 262.
Append the next digit (6) from the dividend to 262 and continue with: 2626 / 280

On to step 8:
280 can be fit into 2626 9 times, resulting in a remainder of 106.
Use 9 as the next digit of our solution. 
Result so far: 313959.0
The remainder is 106 after subtracting 2520 from 2626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 9:
If we divide 1060 by 280, we get 3 and a remainder of 220.
The number 3 becomes the next digit in our result. 
Result so far: 313959.3
If we subtract 840 from 1060, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 10:
The number 280 fits into 2200 7 times, leaving a remainder of 240.
The number 7 becomes the next digit in our result. 
Result so far: 313959.37
Subtract 1960 from 2200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
If we divide 2400 by 280, we get 8 and a remainder of 160.
The next digit of our result is 8. 
Result so far: 313959.378
Subtract 2240 from 2400 to get 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:
280 can be fit into 1600 5 times, resulting in a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 313959.3785
Subtract 1400 from 1600 to get 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:
The number 280 fits into 2000 7 times, leaving a remainder of 40.
The next digit of our result is 7. 
Result so far: 313959.37857
Deduct 1960 from 2000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
400 divided by 280 is 1 with a remainder of 120.
The number 1 becomes the next digit in our result. 
Result so far: 313959.378571
The remainder is 120 after subtracting 280 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 15:
280 goes into 1200 4 times with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 313959.3785714
Deduct 1120 from 1200 and we're left 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.

Moving on to step 16:
If we divide 800 by 280, we get 2 and a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 313959.37857142
Subtract 560 from 800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

In conclusion, the division gives 313959.37857142 with a balance of 2.4e-07.
