21855266 ÷ 177 
The aim is to understand the frequency of 177 in 21855266.

Advancing to step 1:
The number 177 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 177

Going ahead to step 2:
177 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 177

Moving on to step 3:
The number 177 fits into 218 1 times, leaving a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 177 away from 218, we end up with 41.
Include the next digit (5) from the dividend after 41, then repeat: 415 / 177

Step 4:
177 can be fit into 415 2 times, resulting in a remainder of 61.
The next digit of our result is 2. 
Result so far: 12.0
If we take 354 away from 415, we end up with 61.
Fetch the next digit (5) from the dividend, attach it to 61 and continue: 615 / 177

On to step 5:
When dividing 615 by 177, we get 3 with a remainder of 84.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 531 from 615 leaves us with 84.
Grab the next digit (2) from the dividend, add it to 84, then carry on: 842 / 177

On to step 6:
If we divide 842 by 177, we get 4 and a remainder of 134.
The next digit of our result is 4. 
Result so far: 1234.0
If we subtract 708 from 842, we get 134.
Include the next digit (6) from the dividend after 134, then repeat: 1346 / 177

Advancing to step 7:
177 can be fit into 1346 7 times, resulting in a remainder of 107.
The next digit of our result is 7. 
Result so far: 12347.0
Subtract 1239 from 1346 to get 107.
Bring next digit (6) of the dividend behind the 107 and repeat the process: 1076 / 177

Let's proceed to step 8:
1076 divided by 177 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 123476.0
Subtracting 1062 from 1076 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 177 is 0 with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 123476.0
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
If we divide 1400 by 177, we get 7 and a remainder of 161.
The next digit of our result is 7. 
Result so far: 123476.07
Subtracting 1239 from 1400 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 11:
177 can be fit into 1610 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 123476.079
If we subtract 1593 from 1610, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
177 can be fit into 170 0 times, resulting in a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 123476.079
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 13:
The number 177 fits into 1700 9 times, leaving a remainder of 107.
Put 9 as the next digit of the answer. 
Result so far: 123476.07909
Subtracting 1593 from 1700 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 14:
If we divide 1070 by 177, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 123476.079096
Subtract 1062 from 1070 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 15:
If we divide 80 by 177, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 123476.079096
Deduct 0 from 80 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.

Step 16:
177 goes into 800 4 times with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 123476.07909604
Subtract 708 from 800 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 123476.07909604 with a remaining 9.2e-08.
