651699 divided by 77 
The aim is to understand the frequency of 77 in 651699.

On to step 1:
77 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 77

On to step 2:
If we divide 65 by 77, we get 0 and a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 77

Going ahead to step 3:
77 goes into 651 8 times with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 616 away from 651, we end up with 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 77

Going ahead to step 4:
When dividing 356 by 77, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we take 308 away from 356, we end up with 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 77

Advancing to step 5:
The number 77 fits into 489 6 times, leaving a remainder of 27.
Record the quotient 6 as the next digit in the result. 
Result so far: 846.0
Subtracting 462 from 489 leaves us with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 77

Let's proceed to step 6:
If we divide 279 by 77, we get 3 and a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 8463.0
If we subtract 231 from 279, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
77 goes into 480 6 times with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 8463.6
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
77 can be fit into 180 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 8463.62
If we subtract 154 from 180, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
If we divide 260 by 77, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 8463.623
If we take 231 away from 260, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
77 can be fit into 290 3 times, resulting in a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 8463.6233
If we take 231 away from 290, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Our division results in 8463.6233 with a remaining 0.00059.
