17245031 ÷ 878 
The aim is to understand the frequency of 878 in 17245031.

Step 1:
1 divided by 878 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 878

On to step 2:
If we divide 17 by 878, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 878

On to step 3:
878 goes into 172 0 times with a remainder of 172.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 172 to get 172.
Append the next digit (4) from the dividend to 172 and continue with: 1724 / 878

Moving on to step 4:
878 can be fit into 1724 1 times, resulting in a remainder of 846.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 878 from 1724 to get 846.
Fetch the next digit (5) from the dividend, attach it to 846 and continue: 8465 / 878

On to step 5:
The number 878 fits into 8465 9 times, leaving a remainder of 563.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 7902 from 8465 to get 563.
Fetch the next digit (0) from the dividend, attach it to 563 and continue: 5630 / 878

Let's proceed to step 6:
When dividing 5630 by 878, we get 6 with a remainder of 362.
Record the quotient 6 as the next digit in the result. 
Result so far: 196.0
If we subtract 5268 from 5630, we get 362.
Bring next digit (3) of the dividend behind the 362 and repeat the process: 3623 / 878

On to step 7:
878 can be fit into 3623 4 times, resulting in a remainder of 111.
The number 4 becomes the next digit in our result. 
Result so far: 1964.0
The remainder is 111 after subtracting 3512 from 3623.
Fetch the next digit (1) from the dividend, attach it to 111 and continue: 1111 / 878

Going ahead to step 8:
When dividing 1111 by 878, we get 1 with a remainder of 233.
The next digit of our result is 1. 
Result so far: 19641.0
The remainder is 233 after subtracting 878 from 1111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 9:
If we divide 2330 by 878, we get 2 and a remainder of 574.
The number 2 becomes the next digit in our result. 
Result so far: 19641.2
The remainder is 574 after subtracting 1756 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Let's proceed to step 10:
When dividing 5740 by 878, we get 6 with a remainder of 472.
Record the quotient 6 as the next digit in the result. 
Result so far: 19641.26
Subtracting 5268 from 5740 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 11:
4720 divided by 878 is 5 with a remainder of 330.
Write down 5 as next digit of the result. 
Result so far: 19641.265
Deduct 4390 from 4720 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 12:
When dividing 3300 by 878, we get 3 with a remainder of 666.
The number 3 becomes the next digit in our result. 
Result so far: 19641.2653
If we take 2634 away from 3300, we end up with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

On to step 13:
When dividing 6660 by 878, we get 7 with a remainder of 514.
The number 7 becomes the next digit in our result. 
Result so far: 19641.26537
Subtract 6146 from 6660 to get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 14:
5140 divided by 878 is 5 with a remainder of 750.
The next digit of our result is 5. 
Result so far: 19641.265375
If we subtract 4390 from 5140, we get 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

On to step 15:
If we divide 7500 by 878, we get 8 and a remainder of 476.
Write down 8 as next digit of the result. 
Result so far: 19641.2653758
Deduct 7024 from 7500 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

On to step 16:
When dividing 4760 by 878, we get 5 with a remainder of 370.
Record the quotient 5 as the next digit in the result. 
Result so far: 19641.26537585
The remainder is 370 after subtracting 4390 from 4760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

The final result is 19641.26537585 with a remainder of 3.7e-07.
