44971596 ÷ 77 
The aim is to understand the frequency of 77 in 44971596.

Moving on to step 1:
The number 77 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 77

Moving on to step 2:
77 can be fit into 44 0 times, resulting in a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 77

Let's proceed to step 3:
The number 77 fits into 449 5 times, leaving a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 385 from 449 and we're left with 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 77

Step 4:
The number 77 fits into 647 8 times, leaving a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 58.0
If we take 616 away from 647, we end up with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 77

Moving on to step 5:
When dividing 311 by 77, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 584.0
Subtract 308 from 311 to get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 77

Going ahead to step 6:
77 can be fit into 35 0 times, resulting in a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 5840.0
If we take 0 away from 35, we end up with 35.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 77

Moving on to step 7:
77 can be fit into 359 4 times, resulting in a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 58404.0
Deduct 308 from 359 and we're left with 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 77

Moving on to step 8:
77 goes into 516 6 times with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 584046.0
The remainder is 54 after subtracting 462 from 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 584046.7
If we subtract 539 from 540, we get 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 10:
10 divided by 77 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 584046.7
If we take 0 away from 10, we end up 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.

Going ahead to step 11:
100 divided by 77 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 584046.701
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
230 divided by 77 is 2 with a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 584046.7012
Deduct 154 from 230 and we're left 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.

Let's proceed to step 13:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 584046.70129
Deduct 693 from 760 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 14:
When dividing 670 by 77, we get 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 584046.701298
Subtract 616 from 670 to 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.

Step 15:
If we divide 540 by 77, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 584046.7012987
If we subtract 539 from 540, we get 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 16:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 584046.7012987
If we take 0 away from 10, we end up 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.

After the division, we end up with 584046.7012987 and a remainder of 1e-08.
