754655 ÷ 77 
The aim is to understand the frequency of 77 in 754655.

On to step 1:
77 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 77

On to step 2:
When dividing 75 by 77, we get 0 with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 77

Advancing to step 3:
77 goes into 754 9 times with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 693 from 754 and we're left with 61.
Take the next digit (6) from the dividend and append it to 61, then repeat: 616 / 77

Step 4:
The number 77 fits into 616 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 98.0
If we subtract 616 from 616, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 77

Let's proceed to step 5:
When dividing 5 by 77, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 980.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 77

Moving on to step 6:
If we divide 55 by 77, we get 0 and a remainder of 55.
The next digit of our result is 0. 
Result so far: 9800.0
Subtracting 0 from 55 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 7:
77 goes into 550 7 times with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 9800.7
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.

Advancing to step 8:
77 goes into 110 1 times with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 9800.71
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.

On to step 9:
77 goes into 330 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 9800.714
The remainder is 22 after subtracting 308 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 10:
If we divide 220 by 77, we get 2 and a remainder of 66.
Record the quotient 2 as the next digit in the result. 
Result so far: 9800.7142
The remainder is 66 after subtracting 154 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
77 goes into 660 8 times with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 9800.71428
If we subtract 616 from 660, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
The number 77 fits into 440 5 times, leaving a remainder of 55.
The next digit of our result is 5. 
Result so far: 9800.714285
If we subtract 385 from 440, we 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.

Moving on to step 13:
If we divide 550 by 77, we get 7 and a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 9800.7142857
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.

Advancing to step 14:
The number 77 fits into 110 1 times, leaving a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 9800.71428571
If we take 77 away from 110, we end up 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.

The final result is 9800.71428571 with a remainder of 3.3e-08.
