810568 divided by 77 
The aim is to understand the frequency of 77 in 810568.

Step 1:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 77

Let's proceed to step 2:
If we divide 81 by 77, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 77 away from 81, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 77

Let's proceed to step 3:
If we divide 40 by 77, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 40, we get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 77

Moving on to step 4:
405 divided by 77 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 385 from 405 leaves us with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 77

Going ahead to step 5:
77 can be fit into 206 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 1052.0
The remainder is 52 after subtracting 154 from 206.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 77

Advancing to step 6:
When dividing 528 by 77, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 10526.0
The remainder is 66 after subtracting 462 from 528.
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 7:
If we divide 660 by 77, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 10526.8
If we take 616 away from 660, we end up with 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 8:
When dividing 440 by 77, we get 5 with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 10526.85
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.

Step 9:
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: 10526.857
Subtract 539 from 550 to 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.

Moving on to step 10:
110 divided by 77 is 1 with a remainder of 33.
Use 1 as the next digit of our solution. 
Result so far: 10526.8571
If we subtract 77 from 110, we 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.

Going ahead to step 11:
330 divided by 77 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 10526.85714
If we take 308 away from 330, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
When dividing 220 by 77, we get 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 10526.857142
If we subtract 154 from 220, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 13:
If we divide 660 by 77, we get 8 and a remainder of 44.
The next digit of our result is 8. 
Result so far: 10526.8571428
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.

Step 14:
If we divide 440 by 77, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 10526.85714285
If we take 385 away from 440, we end up 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.

The final outcome is 10526.85714285, with a leftover of 5.5e-08.
