918227 divided by 77 
The aim is to understand the frequency of 77 in 918227.

On to step 1:
9 divided by 77 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 77

Going ahead to step 2:
If we divide 91 by 77, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 77 from 91 and we're left with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 77

Moving on to step 3:
77 can be fit into 148 1 times, resulting in a remainder of 71.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 77 from 148 and we're left with 71.
Take the next digit (2) from the dividend and append it to 71, then repeat: 712 / 77

On to step 4:
712 divided by 77 is 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtracting 693 from 712 leaves us with 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 77

Let's proceed to step 5:
The number 77 fits into 192 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 1192.0
Subtracting 154 from 192 leaves us with 38.
Take the next digit (7) from the dividend and append it to 38, then repeat: 387 / 77

Advancing to step 6:
387 divided by 77 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 11925.0
If we subtract 385 from 387, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
77 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11925.0
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
77 goes into 200 2 times with a remainder of 46.
Put 2 as the next digit of the answer. 
Result so far: 11925.02
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
77 goes into 460 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 11925.025
Subtracting 385 from 460 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 10:
When dividing 750 by 77, we get 9 with a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 11925.0259
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 11:
77 goes into 570 7 times with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 11925.02597
Subtracting 539 from 570 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
When dividing 310 by 77, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 11925.025974
Subtract 308 from 310 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
When dividing 20 by 77, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 11925.025974
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
77 goes into 200 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 11925.02597402
Subtract 154 from 200 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 11925.02597402, with a leftover of 4.6e-08.
