We're dividing 423708 by 77 
The aim is to understand the frequency of 77 in 423708.

Advancing to step 1:
The number 77 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 77

Step 2:
77 can be fit into 42 0 times, resulting in a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 77

Going ahead to step 3:
77 can be fit into 423 5 times, resulting in a remainder of 38.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 385 from 423 and we're left with 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 77

Advancing to step 4:
The number 77 fits into 387 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we take 385 away from 387, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 77

Advancing to step 5:
When dividing 20 by 77, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 550.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 77

Going ahead to step 6:
The number 77 fits into 208 2 times, leaving a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 5502.0
If we subtract 154 from 208, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
If we divide 540 by 77, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 5502.7
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
The number 77 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5502.7
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
100 divided by 77 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 5502.701
Subtracting 77 from 100 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
230 divided by 77 is 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 5502.7012
If we take 154 away from 230, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
If we divide 760 by 77, we get 9 and a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 5502.70129
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 12:
77 can be fit into 670 8 times, resulting in a remainder of 54.
The next digit of our result is 8. 
Result so far: 5502.701298
Subtracting 616 from 670 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 5502.7012987
Subtracting 539 from 540 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 14:
10 divided by 77 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 5502.7012987
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 5502.7012987 with a remainder of 1e-08.
