We're dividing 597961 by 77 
The aim is to understand the frequency of 77 in 597961.

Advancing to step 1:
If we divide 5 by 77, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 77

Going ahead to step 2:
77 goes into 59 0 times with a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 59 to get 59.
Grab the next digit (7) from the dividend, add it to 59, then carry on: 597 / 77

Step 3:
When dividing 597 by 77, we get 7 with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 539 from 597 to get 58.
Append the next digit (9) from the dividend to 58 and continue with: 589 / 77

Going ahead to step 4:
If we divide 589 by 77, we get 7 and a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Deduct 539 from 589 and we're left with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 77

On to step 5:
77 goes into 506 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 776.0
If we subtract 462 from 506, we get 44.
Take the next digit (1) from the dividend and append it to 44, then repeat: 441 / 77

Moving on to step 6:
441 divided by 77 is 5 with a remainder of 56.
Put 5 as the next digit of the answer. 
Result so far: 7765.0
If we subtract 385 from 441, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
The number 77 fits into 560 7 times, leaving a remainder of 21.
The next digit of our result is 7. 
Result so far: 7765.7
Deduct 539 from 560 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
77 goes into 210 2 times with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 7765.72
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
560 divided by 77 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 7765.727
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
77 can be fit into 210 2 times, resulting in a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 7765.7272
Subtract 154 from 210 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
77 can be fit into 560 7 times, resulting in a remainder of 21.
The next digit of our result is 7. 
Result so far: 7765.72727
Subtracting 539 from 560 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 12:
77 goes into 210 2 times with a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 7765.727272
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
77 goes into 560 7 times with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 7765.7272727
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 14:
The number 77 fits into 210 2 times, leaving a remainder of 56.
The next digit of our result is 2. 
Result so far: 7765.72727272
Subtracting 154 from 210 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 7765.72727272 with a remaining 5.6e-08.
