We're dividing 390044 by 77 
The aim is to understand the frequency of 77 in 390044.

Moving on to step 1:
The number 77 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 77

Moving on to step 2:
77 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 77

Advancing to step 3:
77 goes into 390 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 385 from 390 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 77

Moving on to step 4:
The number 77 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 50 to get 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 77

Advancing to step 5:
If we divide 504 by 77, we get 6 and a remainder of 42.
The next digit of our result is 6. 
Result so far: 506.0
If we take 462 away from 504, we end up with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 77

Moving on to step 6:
The number 77 fits into 424 5 times, leaving a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 5065.0
If we take 385 away from 424, we end up 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.

Let's proceed to step 7:
If we divide 390 by 77, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5065.5
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.

Going ahead to step 8:
77 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5065.5
If we take 0 away from 50, we end up with 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 goes into 500 6 times with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 5065.506
Deduct 462 from 500 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
When dividing 380 by 77, we get 4 with a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 5065.5064
If we take 308 away from 380, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 11:
If we divide 720 by 77, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 5065.50649
Subtract 693 from 720 to get 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: 5065.506493
If we take 231 away from 270, we end up 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.
The next digit of our result is 5. 
Result so far: 5065.5064935
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.

Let's proceed to step 14:
When dividing 50 by 77, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 5065.5064935
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 5065.5064935 and a remainder of 5e-08.
