19784821 ÷ 877 
The aim is to understand the frequency of 877 in 19784821.

Advancing to step 1:
877 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 877

On to step 2:
877 goes into 19 0 times with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 877

Going ahead to step 3:
When dividing 197 by 877, we get 0 with a remainder of 197.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 197, we get 197.
Bring next digit (8) of the dividend behind the 197 and repeat the process: 1978 / 877

On to step 4:
The number 877 fits into 1978 2 times, leaving a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1754 from 1978 and we're left with 224.
Grab the next digit (4) from the dividend, add it to 224, then carry on: 2244 / 877

Step 5:
When dividing 2244 by 877, we get 2 with a remainder of 490.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we take 1754 away from 2244, we end up with 490.
Take the next digit (8) from the dividend and append it to 490, then repeat: 4908 / 877

Going ahead to step 6:
4908 divided by 877 is 5 with a remainder of 523.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Subtract 4385 from 4908 to get 523.
Append the next digit (2) from the dividend to 523 and continue with: 5232 / 877

Let's proceed to step 7:
If we divide 5232 by 877, we get 5 and a remainder of 847.
The next digit of our result is 5. 
Result so far: 2255.0
Subtract 4385 from 5232 to get 847.
Fetch the next digit (1) from the dividend, attach it to 847 and continue: 8471 / 877

Going ahead to step 8:
8471 divided by 877 is 9 with a remainder of 578.
The number 9 becomes the next digit in our result. 
Result so far: 22559.0
Subtract 7893 from 8471 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 9:
If we divide 5780 by 877, we get 6 and a remainder of 518.
Record the quotient 6 as the next digit in the result. 
Result so far: 22559.6
The remainder is 518 after subtracting 5262 from 5780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Going ahead to step 10:
5180 divided by 877 is 5 with a remainder of 795.
The next digit of our result is 5. 
Result so far: 22559.65
Subtract 4385 from 5180 to get 795.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7950, and continue the process.

Going ahead to step 11:
When dividing 7950 by 877, we get 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 22559.659
If we subtract 7893 from 7950, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
When dividing 570 by 877, we get 0 with a remainder of 570.
The next digit of our result is 0. 
Result so far: 22559.659
Subtract 0 from 570 to get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 13:
877 goes into 5700 6 times with a remainder of 438.
Put 6 as the next digit of the answer. 
Result so far: 22559.65906
Subtract 5262 from 5700 to get 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Step 14:
When dividing 4380 by 877, we get 4 with a remainder of 872.
Write down 4 as next digit of the result. 
Result so far: 22559.659064
The remainder is 872 after subtracting 3508 from 4380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Step 15:
When dividing 8720 by 877, we get 9 with a remainder of 827.
Use 9 as the next digit of our solution. 
Result so far: 22559.6590649
Subtract 7893 from 8720 to get 827.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8270, and continue the process.

Moving on to step 16:
877 can be fit into 8270 9 times, resulting in a remainder of 377.
Put 9 as the next digit of the answer. 
Result so far: 22559.65906499
The remainder is 377 after subtracting 7893 from 8270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Our division results in 22559.65906499 with a remaining 3.77e-07.
