28377779 ÷ 77 
The aim is to understand the frequency of 77 in 28377779.

On to step 1:
77 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 77

Going ahead to step 2:
When dividing 28 by 77, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 77

Moving on to step 3:
283 divided by 77 is 3 with a remainder of 52.
The next digit of our result is 3. 
Result so far: 3.0
If we take 231 away from 283, we end up with 52.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 77

On to step 4:
77 can be fit into 527 6 times, resulting in a remainder of 65.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Deduct 462 from 527 and we're left with 65.
Append the next digit (7) from the dividend to 65 and continue with: 657 / 77

Step 5:
The number 77 fits into 657 8 times, leaving a remainder of 41.
Put 8 as the next digit of the answer. 
Result so far: 368.0
Subtracting 616 from 657 leaves us with 41.
Fetch the next digit (7) from the dividend, attach it to 41 and continue: 417 / 77

On to step 6:
77 can be fit into 417 5 times, resulting in a remainder of 32.
The next digit of our result is 5. 
Result so far: 3685.0
If we take 385 away from 417, we end up with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 77

Advancing to step 7:
When dividing 327 by 77, we get 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 36854.0
If we subtract 308 from 327, we get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 77

Going ahead to step 8:
77 can be fit into 199 2 times, resulting in a remainder of 45.
Write down 2 as next digit of the result. 
Result so far: 368542.0
If we take 154 away from 199, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
When dividing 450 by 77, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 368542.5
Subtract 385 from 450 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 10:
If we divide 650 by 77, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 368542.58
Subtract 616 from 650 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
340 divided by 77 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 368542.584
If we subtract 308 from 340, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
77 goes into 320 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 368542.5844
Deduct 308 from 320 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 368542.5844 with a remaining 0.00012.
