We're dividing 860437 by 77 
The aim is to understand the frequency of 77 in 860437.

Going ahead to step 1:
8 divided by 77 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 77

Let's proceed to step 2:
86 divided by 77 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 77 from 86 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 77

Going ahead to step 3:
The number 77 fits into 90 1 times, leaving a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 77 from 90, we get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 77

Going ahead to step 4:
77 can be fit into 134 1 times, resulting in a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
If we subtract 77 from 134, we get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 77

On to step 5:
77 can be fit into 573 7 times, resulting in a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 1117.0
Subtracting 539 from 573 leaves us with 34.
Include the next digit (7) from the dividend after 34, then repeat: 347 / 77

Step 6:
77 can be fit into 347 4 times, resulting in a remainder of 39.
The next digit of our result is 4. 
Result so far: 11174.0
If we subtract 308 from 347, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
390 divided by 77 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11174.5
The remainder is 5 after subtracting 385 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
77 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 11174.5
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
77 can be fit into 500 6 times, resulting in a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 11174.506
Subtract 462 from 500 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
The number 77 fits into 380 4 times, leaving a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 11174.5064
Subtract 308 from 380 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 11:
77 goes into 720 9 times with a remainder of 27.
The next digit of our result is 9. 
Result so far: 11174.50649
Deduct 693 from 720 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 12:
77 can be fit into 270 3 times, resulting in a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 11174.506493
Deduct 231 from 270 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 13:
If we divide 390 by 77, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 11174.5064935
Subtract 385 from 390 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
77 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 11174.5064935
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 11174.5064935 with a remainder of 5e-08.
