We divide 18879323 by 878
The aim is to understand the frequency of 878 in 18879323.

Advancing to step 1:
878 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 878

Advancing to step 2:
The number 878 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 878

On to step 3:
When dividing 188 by 878, we get 0 with a remainder of 188.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 188 leaves us with 188.
Fetch the next digit (7) from the dividend, attach it to 188 and continue: 1887 / 878

Advancing to step 4:
When dividing 1887 by 878, we get 2 with a remainder of 131.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 131 after subtracting 1756 from 1887.
Take the next digit (9) from the dividend and append it to 131, then repeat: 1319 / 878

On to step 5:
1319 divided by 878 is 1 with a remainder of 441.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 878 from 1319 and we're left with 441.
Fetch the next digit (3) from the dividend, attach it to 441 and continue: 4413 / 878

Going ahead to step 6:
4413 divided by 878 is 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 215.0
The remainder is 23 after subtracting 4390 from 4413.
Take the next digit (2) from the dividend and append it to 23, then repeat: 232 / 878

Advancing to step 7:
878 can be fit into 232 0 times, resulting in a remainder of 232.
Use 0 as the next digit of our solution. 
Result so far: 2150.0
If we take 0 away from 232, we end up with 232.
Grab the next digit (3) from the dividend, add it to 232, then carry on: 2323 / 878

Advancing to step 8:
878 can be fit into 2323 2 times, resulting in a remainder of 567.
The next digit of our result is 2. 
Result so far: 21502.0
If we take 1756 away from 2323, we end up 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 9:
The number 878 fits into 5670 6 times, leaving a remainder of 402.
Put 6 as the next digit of the answer. 
Result so far: 21502.6
Subtracting 5268 from 5670 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 10:
878 goes into 4020 4 times with a remainder of 508.
Record the quotient 4 as the next digit in the result. 
Result so far: 21502.64
The remainder is 508 after subtracting 3512 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

On to step 11:
878 goes into 5080 5 times with a remainder of 690.
The next digit of our result is 5. 
Result so far: 21502.645
If we subtract 4390 from 5080, we get 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Moving on to step 12:
878 can be fit into 6900 7 times, resulting in a remainder of 754.
Use 7 as the next digit of our solution. 
Result so far: 21502.6457
The remainder is 754 after subtracting 6146 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7540, and continue the process.

On to step 13:
When dividing 7540 by 878, we get 8 with a remainder of 516.
The next digit of our result is 8. 
Result so far: 21502.64578
If we subtract 7024 from 7540, we get 516.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Moving on to step 14:
5160 divided by 878 is 5 with a remainder of 770.
Put 5 as the next digit of the answer. 
Result so far: 21502.645785
If we take 4390 away from 5160, we end up with 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 15:
878 can be fit into 7700 8 times, resulting in a remainder of 676.
The number 8 becomes the next digit in our result. 
Result so far: 21502.6457858
Deduct 7024 from 7700 and we're left with 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

Step 16:
6760 divided by 878 is 7 with a remainder of 614.
The number 7 becomes the next digit in our result. 
Result so far: 21502.64578587
Subtract 6146 from 6760 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Our division results in 21502.64578587 with a remaining 6.14e-07.
