We look at the division of 98573802 by 878 
The aim is to understand the frequency of 878 in 98573802.

Let's proceed to step 1:
If we divide 9 by 878, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 878

Step 2:
The number 878 fits into 98 0 times, leaving a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 98 leaves us with 98.
Grab the next digit (5) from the dividend, add it to 98, then carry on: 985 / 878

On to step 3:
878 goes into 985 1 times with a remainder of 107.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 878 from 985 and we're left with 107.
Include the next digit (7) from the dividend after 107, then repeat: 1077 / 878

Going ahead to step 4:
If we divide 1077 by 878, we get 1 and a remainder of 199.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 199 after subtracting 878 from 1077.
Bring next digit (3) of the dividend behind the 199 and repeat the process: 1993 / 878

Going ahead to step 5:
When dividing 1993 by 878, we get 2 with a remainder of 237.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Subtracting 1756 from 1993 leaves us with 237.
Grab the next digit (8) from the dividend, add it to 237, then carry on: 2378 / 878

Advancing to step 6:
878 can be fit into 2378 2 times, resulting in a remainder of 622.
Put 2 as the next digit of the answer. 
Result so far: 1122.0
Subtract 1756 from 2378 to get 622.
Bring next digit (0) of the dividend behind the 622 and repeat the process: 6220 / 878

On to step 7:
The number 878 fits into 6220 7 times, leaving a remainder of 74.
Record the quotient 7 as the next digit in the result. 
Result so far: 11227.0
Subtracting 6146 from 6220 leaves us with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 878

Let's proceed to step 8:
878 goes into 742 0 times with a remainder of 742.
The number 0 becomes the next digit in our result. 
Result so far: 112270.0
Subtract 0 from 742 to get 742.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7420, and continue the process.

Advancing to step 9:
When dividing 7420 by 878, we get 8 with a remainder of 396.
Put 8 as the next digit of the answer. 
Result so far: 112270.8
The remainder is 396 after subtracting 7024 from 7420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 10:
3960 divided by 878 is 4 with a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 112270.84
Subtracting 3512 from 3960 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 11:
878 goes into 4480 5 times with a remainder of 90.
The next digit of our result is 5. 
Result so far: 112270.845
If we take 4390 away from 4480, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 12:
When dividing 900 by 878, we get 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 112270.8451
Subtract 878 from 900 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
The number 878 fits into 220 0 times, leaving a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 112270.8451
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 14:
If we divide 2200 by 878, we get 2 and a remainder of 444.
Put 2 as the next digit of the answer. 
Result so far: 112270.845102
The remainder is 444 after subtracting 1756 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 15:
4440 divided by 878 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 112270.8451025
If we subtract 4390 from 4440, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 16:
878 goes into 500 0 times with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 112270.8451025
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The quotient of the division is 112270.8451025, and the remainder is 5e-07.
