We look at the division of 73647007 by 878 
The aim is to understand the frequency of 878 in 73647007.

Step 1:
878 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 878

Advancing to step 2:
878 can be fit into 73 0 times, resulting in a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 878

Step 3:
878 can be fit into 736 0 times, resulting in a remainder of 736.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 736 leaves us with 736.
Include the next digit (4) from the dividend after 736, then repeat: 7364 / 878

Let's proceed to step 4:
878 can be fit into 7364 8 times, resulting in a remainder of 340.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 340 after subtracting 7024 from 7364.
Append the next digit (7) from the dividend to 340 and continue with: 3407 / 878

Step 5:
When dividing 3407 by 878, we get 3 with a remainder of 773.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtracting 2634 from 3407 leaves us with 773.
Fetch the next digit (0) from the dividend, attach it to 773 and continue: 7730 / 878

Advancing to step 6:
878 goes into 7730 8 times with a remainder of 706.
The number 8 becomes the next digit in our result. 
Result so far: 838.0
Deduct 7024 from 7730 and we're left with 706.
Bring next digit (0) of the dividend behind the 706 and repeat the process: 7060 / 878

Step 7:
878 goes into 7060 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8388.0
If we take 7024 away from 7060, we end up with 36.
Append the next digit (7) from the dividend to 36 and continue with: 367 / 878

Advancing to step 8:
878 can be fit into 367 0 times, resulting in a remainder of 367.
The number 0 becomes the next digit in our result. 
Result so far: 83880.0
Subtract 0 from 367 to get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 9:
878 can be fit into 3670 4 times, resulting in a remainder of 158.
The number 4 becomes the next digit in our result. 
Result so far: 83880.4
If we take 3512 away from 3670, we end up with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 10:
When dividing 1580 by 878, we get 1 with a remainder of 702.
The next digit of our result is 1. 
Result so far: 83880.41
If we take 878 away from 1580, we end up with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

Moving on to step 11:
878 can be fit into 7020 7 times, resulting in a remainder of 874.
The number 7 becomes the next digit in our result. 
Result so far: 83880.417
Subtracting 6146 from 7020 leaves us with 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Let's proceed to step 12:
When dividing 8740 by 878, we get 9 with a remainder of 838.
Put 9 as the next digit of the answer. 
Result so far: 83880.4179
Deduct 7902 from 8740 and we're left with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Advancing to step 13:
The number 878 fits into 8380 9 times, leaving a remainder of 478.
Write down 9 as next digit of the result. 
Result so far: 83880.41799
The remainder is 478 after subtracting 7902 from 8380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

In conclusion, the division gives 83880.41799 with a balance of 0.000478.
