10665947 divided by 877 
The aim is to understand the frequency of 877 in 10665947.

Let's proceed to step 1:
If we divide 1 by 877, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 877

Moving on to step 2:
877 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: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 877

Going ahead to step 3:
The number 877 fits into 106 0 times, leaving a remainder of 106.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 106 to get 106.
Include the next digit (6) from the dividend after 106, then repeat: 1066 / 877

Let's proceed to step 4:
877 can be fit into 1066 1 times, resulting in a remainder of 189.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 877 away from 1066, we end up with 189.
Include the next digit (5) from the dividend after 189, then repeat: 1895 / 877

Moving on to step 5:
If we divide 1895 by 877, we get 2 and a remainder of 141.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1754 away from 1895, we end up with 141.
Append the next digit (9) from the dividend to 141 and continue with: 1419 / 877

Going ahead to step 6:
The number 877 fits into 1419 1 times, leaving a remainder of 542.
Put 1 as the next digit of the answer. 
Result so far: 121.0
Subtracting 877 from 1419 leaves us with 542.
Append the next digit (4) from the dividend to 542 and continue with: 5424 / 877

Advancing to step 7:
When dividing 5424 by 877, we get 6 with a remainder of 162.
The next digit of our result is 6. 
Result so far: 1216.0
Subtract 5262 from 5424 to get 162.
Bring next digit (7) of the dividend behind the 162 and repeat the process: 1627 / 877

Advancing to step 8:
The number 877 fits into 1627 1 times, leaving a remainder of 750.
Use 1 as the next digit of our solution. 
Result so far: 12161.0
If we take 877 away from 1627, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Let's proceed to step 9:
877 can be fit into 7500 8 times, resulting in a remainder of 484.
The next digit of our result is 8. 
Result so far: 12161.8
Deduct 7016 from 7500 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 10:
877 can be fit into 4840 5 times, resulting in a remainder of 455.
The number 5 becomes the next digit in our result. 
Result so far: 12161.85
Subtract 4385 from 4840 to get 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Going ahead to step 11:
When dividing 4550 by 877, we get 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 12161.855
Deduct 4385 from 4550 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The quotient of the division is 12161.855, and the remainder is 0.0165.
