77221997 ÷ 911 
The aim is to understand the frequency of 911 in 77221997.

Advancing to step 1:
911 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 911

Let's proceed to step 2:
When dividing 77 by 911, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (2) of the dividend behind the 77 and repeat the process: 772 / 911

Moving on to step 3:
When dividing 772 by 911, we get 0 with a remainder of 772.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 772 to get 772.
Take the next digit (2) from the dividend and append it to 772, then repeat: 7722 / 911

Step 4:
911 can be fit into 7722 8 times, resulting in a remainder of 434.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7288 from 7722 to get 434.
Take the next digit (1) from the dividend and append it to 434, then repeat: 4341 / 911

Step 5:
The number 911 fits into 4341 4 times, leaving a remainder of 697.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 3644 from 4341, we get 697.
Append the next digit (9) from the dividend to 697 and continue with: 6979 / 911

Going ahead to step 6:
911 goes into 6979 7 times with a remainder of 602.
The next digit of our result is 7. 
Result so far: 847.0
The remainder is 602 after subtracting 6377 from 6979.
Grab the next digit (9) from the dividend, add it to 602, then carry on: 6029 / 911

Let's proceed to step 7:
6029 divided by 911 is 6 with a remainder of 563.
The next digit of our result is 6. 
Result so far: 8476.0
If we subtract 5466 from 6029, we get 563.
Fetch the next digit (7) from the dividend, attach it to 563 and continue: 5637 / 911

On to step 8:
911 can be fit into 5637 6 times, resulting in a remainder of 171.
The number 6 becomes the next digit in our result. 
Result so far: 84766.0
If we subtract 5466 from 5637, we get 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Let's proceed to step 9:
1710 divided by 911 is 1 with a remainder of 799.
Use 1 as the next digit of our solution. 
Result so far: 84766.1
The remainder is 799 after subtracting 911 from 1710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Moving on to step 10:
911 goes into 7990 8 times with a remainder of 702.
Record the quotient 8 as the next digit in the result. 
Result so far: 84766.18
If we take 7288 away from 7990, we end up with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

On to step 11:
If we divide 7020 by 911, we get 7 and a remainder of 643.
The number 7 becomes the next digit in our result. 
Result so far: 84766.187
If we subtract 6377 from 7020, we get 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Let's proceed to step 12:
6430 divided by 911 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 84766.1877
If we subtract 6377 from 6430, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

The quotient of the division is 84766.1877, and the remainder is 0.00053.
