We divide 7947977 by 911
The aim is to understand the frequency of 911 in 7947977.

Let's proceed to step 1:
7 divided by 911 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 911

On to step 2:
911 goes into 79 0 times with a remainder of 79.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 911

Advancing to step 3:
The number 911 fits into 794 0 times, leaving a remainder of 794.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 794 and we're left with 794.
Grab the next digit (7) from the dividend, add it to 794, then carry on: 7947 / 911

Advancing to step 4:
7947 divided by 911 is 8 with a remainder of 659.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 7288 from 7947 and we're left with 659.
Bring next digit (9) of the dividend behind the 659 and repeat the process: 6599 / 911

Step 5:
6599 divided by 911 is 7 with a remainder of 222.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we take 6377 away from 6599, we end up with 222.
Fetch the next digit (7) from the dividend, attach it to 222 and continue: 2227 / 911

Advancing to step 6:
911 goes into 2227 2 times with a remainder of 405.
The number 2 becomes the next digit in our result. 
Result so far: 872.0
The remainder is 405 after subtracting 1822 from 2227.
Bring next digit (7) of the dividend behind the 405 and repeat the process: 4057 / 911

Going ahead to step 7:
911 goes into 4057 4 times with a remainder of 413.
Write down 4 as next digit of the result. 
Result so far: 8724.0
Subtracting 3644 from 4057 leaves us with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Moving on to step 8:
4130 divided by 911 is 4 with a remainder of 486.
Write down 4 as next digit of the result. 
Result so far: 8724.4
Subtract 3644 from 4130 to get 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

Moving on to step 9:
The number 911 fits into 4860 5 times, leaving a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 8724.45
Deduct 4555 from 4860 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 10:
When dividing 3050 by 911, we get 3 with a remainder of 317.
Write down 3 as next digit of the result. 
Result so far: 8724.453
If we subtract 2733 from 3050, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Step 11:
911 goes into 3170 3 times with a remainder of 437.
Record the quotient 3 as the next digit in the result. 
Result so far: 8724.4533
Subtracting 2733 from 3170 leaves us with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

The final result is 8724.4533 with a remainder of 0.00437.
