Let's divide 280413 by 69
The aim is to understand the frequency of 69 in 280413.

On to step 1:
The number 69 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 69

On to step 2:
When dividing 28 by 69, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 69

Going ahead to step 3:
69 goes into 280 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 276 from 280 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 69

Moving on to step 4:
69 goes into 44 0 times with a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 44, we end up with 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 69

On to step 5:
69 can be fit into 441 6 times, resulting in a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 406.0
If we take 414 away from 441, we end up with 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 69

Let's proceed to step 6:
69 goes into 273 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 4063.0
Subtracting 207 from 273 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
When dividing 660 by 69, we get 9 with a remainder of 39.
The next digit of our result is 9. 
Result so far: 4063.9
Deduct 621 from 660 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
When dividing 390 by 69, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 4063.95
The remainder is 45 after subtracting 345 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
When dividing 450 by 69, we get 6 with a remainder of 36.
The next digit of our result is 6. 
Result so far: 4063.956
Subtracting 414 from 450 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
69 can be fit into 360 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 4063.9565
The remainder is 15 after subtracting 345 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
69 goes into 150 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 4063.95652
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
69 can be fit into 120 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 4063.956521
Deduct 69 from 120 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
When dividing 510 by 69, we get 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 4063.9565217
If we subtract 483 from 510, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 14:
When dividing 270 by 69, we get 3 with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 4063.95652173
Subtract 207 from 270 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

After the division, we end up with 4063.95652173 and a remainder of 6.3e-08.
