50971546 ÷ 77 
The aim is to understand the frequency of 77 in 50971546.

Advancing to step 1:
The number 77 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 77

On to step 2:
77 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 77

Advancing to step 3:
509 divided by 77 is 6 with a remainder of 47.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 462 from 509 to get 47.
Include the next digit (7) from the dividend after 47, then repeat: 477 / 77

Let's proceed to step 4:
If we divide 477 by 77, we get 6 and a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtracting 462 from 477 leaves us with 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 77

Step 5:
77 goes into 151 1 times with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 661.0
If we subtract 77 from 151, we get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 77

Step 6:
77 goes into 745 9 times with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 6619.0
If we subtract 693 from 745, we get 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 77

On to step 7:
When dividing 524 by 77, we get 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 66196.0
If we subtract 462 from 524, we get 62.
Grab the next digit (6) from the dividend, add it to 62, then carry on: 626 / 77

Let's proceed to step 8:
If we divide 626 by 77, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 661968.0
If we take 616 away from 626, 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.

Advancing to step 9:
If we divide 100 by 77, we get 1 and a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 661968.1
If we take 77 away from 100, we end up 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.

Let's proceed to step 10:
If we divide 230 by 77, we get 2 and a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 661968.12
Subtracting 154 from 230 leaves us 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:
77 can be fit into 760 9 times, resulting in a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 661968.129
Subtracting 693 from 760 leaves us 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.

Advancing to step 12:
If we divide 670 by 77, we get 8 and a remainder of 54.
Write down 8 as next digit of the result. 
Result so far: 661968.1298
Deduct 616 from 670 and we're left 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.

On to step 13:
If we divide 540 by 77, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 661968.12987
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 14:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 661968.12987
If we subtract 0 from 10, we get 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 15:
When dividing 100 by 77, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 661968.1298701
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.

Going ahead to step 16:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Record the quotient 2 as the next digit in the result. 
Result so far: 661968.12987012
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The quotient of the division is 661968.12987012, and the remainder is 7.6e-08.
