Let's divide 974975 by 77
The aim is to understand the frequency of 77 in 974975.

Step 1:
77 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 77

Going ahead to step 2:
The number 77 fits into 97 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 77 away from 97, we end up with 20.
Take the next digit (4) from the dividend and append it to 20, then repeat: 204 / 77

Going ahead to step 3:
204 divided by 77 is 2 with a remainder of 50.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 154 from 204 to get 50.
Bring next digit (9) of the dividend behind the 50 and repeat the process: 509 / 77

Let's proceed to step 4:
77 can be fit into 509 6 times, resulting in a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we take 462 away from 509, we end up with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 77

Let's proceed to step 5:
When dividing 477 by 77, we get 6 with a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 1266.0
Subtract 462 from 477 to get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 77

On to step 6:
If we divide 155 by 77, we get 2 and a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 12662.0
The remainder is 1 after subtracting 154 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
77 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 12662.0
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.

Let's proceed to step 8:
When dividing 100 by 77, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 12662.01
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 9:
77 can be fit into 230 2 times, resulting in a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 12662.012
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.

Going ahead to step 10:
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: 12662.0129
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.

Step 11:
The number 77 fits into 670 8 times, leaving a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 12662.01298
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.

On to step 12:
The number 77 fits into 540 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 12662.012987
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.

Moving on to step 13:
10 divided by 77 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 12662.012987
Subtract 0 from 10 to 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.

Going ahead to step 14:
If we divide 100 by 77, we get 1 and a remainder of 23.
The next digit of our result is 1. 
Result so far: 12662.01298701
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.

Our division results in 12662.01298701 with a remaining 2.3e-08.
