Let's divide 79861084 by 877
The aim is to understand the frequency of 877 in 79861084.

On to step 1:
7 divided by 877 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 877

Let's proceed to step 2:
The number 877 fits into 79 0 times, leaving a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Bring next digit (8) of the dividend behind the 79 and repeat the process: 798 / 877

Step 3:
877 goes into 798 0 times with a remainder of 798.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 798 and we're left with 798.
Bring next digit (6) of the dividend behind the 798 and repeat the process: 7986 / 877

Going ahead to step 4:
877 goes into 7986 9 times with a remainder of 93.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7893 away from 7986, we end up with 93.
Include the next digit (1) from the dividend after 93, then repeat: 931 / 877

On to step 5:
If we divide 931 by 877, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we take 877 away from 931, we end up with 54.
Append the next digit (0) from the dividend to 54 and continue with: 540 / 877

Advancing to step 6:
If we divide 540 by 877, we get 0 and a remainder of 540.
The number 0 becomes the next digit in our result. 
Result so far: 910.0
If we take 0 away from 540, we end up with 540.
Take the next digit (8) from the dividend and append it to 540, then repeat: 5408 / 877

Going ahead to step 7:
The number 877 fits into 5408 6 times, leaving a remainder of 146.
The number 6 becomes the next digit in our result. 
Result so far: 9106.0
Subtracting 5262 from 5408 leaves us with 146.
Fetch the next digit (4) from the dividend, attach it to 146 and continue: 1464 / 877

Moving on to step 8:
877 goes into 1464 1 times with a remainder of 587.
Write down 1 as next digit of the result. 
Result so far: 91061.0
Deduct 877 from 1464 and we're left with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 9:
877 goes into 5870 6 times with a remainder of 608.
Record the quotient 6 as the next digit in the result. 
Result so far: 91061.6
Subtract 5262 from 5870 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Step 10:
877 can be fit into 6080 6 times, resulting in a remainder of 818.
The number 6 becomes the next digit in our result. 
Result so far: 91061.66
Subtracting 5262 from 6080 leaves us with 818.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8180, and continue the process.

After the division, we end up with 91061.66 and a remainder of 0.818.
