We look at the division of 79107180 by 877 
The aim is to understand the frequency of 877 in 79107180.

Let's proceed to step 1:
If we divide 7 by 877, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 877

Going ahead to step 2:
79 divided by 877 is 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 877

Let's proceed to step 3:
877 can be fit into 791 0 times, resulting in a remainder of 791.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 791, we end up with 791.
Fetch the next digit (0) from the dividend, attach it to 791 and continue: 7910 / 877

Step 4:
7910 divided by 877 is 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 7893 from 7910, we get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 877

Going ahead to step 5:
177 divided by 877 is 0 with a remainder of 177.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 177 and we're left with 177.
Bring next digit (1) of the dividend behind the 177 and repeat the process: 1771 / 877

On to step 6:
If we divide 1771 by 877, we get 2 and a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 902.0
If we subtract 1754 from 1771, we get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 877

On to step 7:
If we divide 178 by 877, we get 0 and a remainder of 178.
Put 0 as the next digit of the answer. 
Result so far: 9020.0
Subtracting 0 from 178 leaves us with 178.
Append the next digit (0) from the dividend to 178 and continue with: 1780 / 877

Moving on to step 8:
877 goes into 1780 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 90202.0
Subtract 1754 from 1780 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
When dividing 260 by 877, we get 0 with a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 90202.0
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 10:
The number 877 fits into 2600 2 times, leaving a remainder of 846.
Record the quotient 2 as the next digit in the result. 
Result so far: 90202.02
Subtracting 1754 from 2600 leaves us with 846.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8460, and continue the process.

On to step 11:
If we divide 8460 by 877, we get 9 and a remainder of 567.
The number 9 becomes the next digit in our result. 
Result so far: 90202.029
Deduct 7893 from 8460 and we're left with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 12:
If we divide 5670 by 877, we get 6 and a remainder of 408.
The number 6 becomes the next digit in our result. 
Result so far: 90202.0296
Subtracting 5262 from 5670 leaves us with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 13:
The number 877 fits into 4080 4 times, leaving a remainder of 572.
Write down 4 as next digit of the result. 
Result so far: 90202.02964
Subtracting 3508 from 4080 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 14:
The number 877 fits into 5720 6 times, leaving a remainder of 458.
The next digit of our result is 6. 
Result so far: 90202.029646
Deduct 5262 from 5720 and we're left with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Let's proceed to step 15:
4580 divided by 877 is 5 with a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 90202.0296465
If we subtract 4385 from 4580, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 16:
When dividing 1950 by 877, we get 2 with a remainder of 196.
The next digit of our result is 2. 
Result so far: 90202.02964652
The remainder is 196 after subtracting 1754 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The quotient of the division is 90202.02964652, and the remainder is 1.96e-07.
