28834315 divided by 77 
The aim is to understand the frequency of 77 in 28834315.

On to step 1:
77 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 77

Let's proceed to step 2:
The number 77 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 77

Step 3:
77 goes into 288 3 times with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 231 away from 288, we end up with 57.
Fetch the next digit (3) from the dividend, attach it to 57 and continue: 573 / 77

Let's proceed to step 4:
77 goes into 573 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 539 from 573, we get 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 77

Advancing to step 5:
77 can be fit into 344 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 374.0
The remainder is 36 after subtracting 308 from 344.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 77

Moving on to step 6:
If we divide 363 by 77, we get 4 and a remainder of 55.
The next digit of our result is 4. 
Result so far: 3744.0
If we take 308 away from 363, we end up with 55.
Take the next digit (1) from the dividend and append it to 55, then repeat: 551 / 77

Advancing to step 7:
If we divide 551 by 77, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 37447.0
The remainder is 12 after subtracting 539 from 551.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 77

On to step 8:
77 can be fit into 125 1 times, resulting in a remainder of 48.
The next digit of our result is 1. 
Result so far: 374471.0
If we take 77 away from 125, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 9:
If we divide 480 by 77, we get 6 and a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 374471.6
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
If we divide 180 by 77, we get 2 and a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 374471.62
If we take 154 away from 180, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
When dividing 260 by 77, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 374471.623
If we subtract 231 from 260, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 12:
77 goes into 290 3 times with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 374471.6233
The remainder is 59 after subtracting 231 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The quotient of the division is 374471.6233, and the remainder is 0.00059.
