We're dividing 990000 by 77 
The aim is to understand the frequency of 77 in 990000.

Let's proceed to step 1:
The number 77 fits into 9 0 times, leaving a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 77

Step 2:
When dividing 99 by 77, we get 1 with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 22 after subtracting 77 from 99.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 77

Step 3:
If we divide 220 by 77, we get 2 and a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 154 from 220 and we're left with 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 77

Advancing to step 4:
660 divided by 77 is 8 with a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 128.0
Subtracting 616 from 660 leaves us with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 77

Step 5:
The number 77 fits into 440 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 1285.0
The remainder is 55 after subtracting 385 from 440.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 77

On to step 6:
When dividing 550 by 77, we get 7 with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 12857.0
Deduct 539 from 550 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
77 goes into 110 1 times with a remainder of 33.
The next digit of our result is 1. 
Result so far: 12857.1
Subtracting 77 from 110 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 8:
When dividing 330 by 77, we get 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 12857.14
Subtract 308 from 330 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
77 goes into 220 2 times with a remainder of 66.
The next digit of our result is 2. 
Result so far: 12857.142
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
When dividing 660 by 77, we get 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 12857.1428
The remainder is 44 after subtracting 616 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
If we divide 440 by 77, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 12857.14285
Subtract 385 from 440 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 12:
If we divide 550 by 77, we get 7 and a remainder of 11.
The next digit of our result is 7. 
Result so far: 12857.142857
If we subtract 539 from 550, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
When dividing 110 by 77, we get 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 12857.1428571
Subtract 77 from 110 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 14:
77 goes into 330 4 times with a remainder of 22.
The next digit of our result is 4. 
Result so far: 12857.14285714
Subtract 308 from 330 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The quotient of the division is 12857.14285714, and the remainder is 2.2e-08.
