28400311 divided by 770 
The aim is to understand the frequency of 770 in 28400311.

Advancing to step 1:
2 divided by 770 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 770

Step 2:
770 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 770

On to step 3:
The number 770 fits into 284 0 times, leaving a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 284 to get 284.
Append the next digit (0) from the dividend to 284 and continue with: 2840 / 770

Let's proceed to step 4:
If we divide 2840 by 770, we get 3 and a remainder of 530.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 2310 from 2840, we get 530.
Grab the next digit (0) from the dividend, add it to 530, then carry on: 5300 / 770

Step 5:
5300 divided by 770 is 6 with a remainder of 680.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 4620 from 5300 leaves us with 680.
Grab the next digit (3) from the dividend, add it to 680, then carry on: 6803 / 770

Going ahead to step 6:
6803 divided by 770 is 8 with a remainder of 643.
Put 8 as the next digit of the answer. 
Result so far: 368.0
Subtracting 6160 from 6803 leaves us with 643.
Include the next digit (1) from the dividend after 643, then repeat: 6431 / 770

On to step 7:
The number 770 fits into 6431 8 times, leaving a remainder of 271.
Use 8 as the next digit of our solution. 
Result so far: 3688.0
If we subtract 6160 from 6431, we get 271.
Bring next digit (1) of the dividend behind the 271 and repeat the process: 2711 / 770

Advancing to step 8:
770 can be fit into 2711 3 times, resulting in a remainder of 401.
Record the quotient 3 as the next digit in the result. 
Result so far: 36883.0
Subtract 2310 from 2711 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 9:
770 goes into 4010 5 times with a remainder of 160.
The next digit of our result is 5. 
Result so far: 36883.5
Deduct 3850 from 4010 and we're left 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.

Moving on to step 10:
If we divide 1600 by 770, we get 2 and a remainder of 60.
The next digit of our result is 2. 
Result so far: 36883.52
If we take 1540 away from 1600, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
600 divided by 770 is 0 with a remainder of 600.
Write down 0 as next digit of the result. 
Result so far: 36883.52
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Moving on to step 12:
770 goes into 6000 7 times with a remainder of 610.
Use 7 as the next digit of our solution. 
Result so far: 36883.5207
The remainder is 610 after subtracting 5390 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 13:
770 can be fit into 6100 7 times, resulting in a remainder of 710.
The number 7 becomes the next digit in our result. 
Result so far: 36883.52077
The remainder is 710 after subtracting 5390 from 6100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

In conclusion, the division gives 36883.52077 with a balance of 0.00071.
