13619257 divided by 874 
The aim is to understand the frequency of 874 in 13619257.

Going ahead to step 1:
If we divide 1 by 874, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 874

Let's proceed to step 2:
13 divided by 874 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 874

On to step 3:
136 divided by 874 is 0 with a remainder of 136.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 136 after subtracting 0 from 136.
Append the next digit (1) from the dividend to 136 and continue with: 1361 / 874

Step 4:
1361 divided by 874 is 1 with a remainder of 487.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 874 from 1361 to get 487.
Include the next digit (9) from the dividend after 487, then repeat: 4879 / 874

Let's proceed to step 5:
874 can be fit into 4879 5 times, resulting in a remainder of 509.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 4370 from 4879 leaves us with 509.
Grab the next digit (2) from the dividend, add it to 509, then carry on: 5092 / 874

Going ahead to step 6:
If we divide 5092 by 874, we get 5 and a remainder of 722.
Put 5 as the next digit of the answer. 
Result so far: 155.0
If we subtract 4370 from 5092, we get 722.
Fetch the next digit (5) from the dividend, attach it to 722 and continue: 7225 / 874

Moving on to step 7:
874 goes into 7225 8 times with a remainder of 233.
Write down 8 as next digit of the result. 
Result so far: 1558.0
If we take 6992 away from 7225, we end up with 233.
Fetch the next digit (7) from the dividend, attach it to 233 and continue: 2337 / 874

Advancing to step 8:
The number 874 fits into 2337 2 times, leaving a remainder of 589.
Use 2 as the next digit of our solution. 
Result so far: 15582.0
The remainder is 589 after subtracting 1748 from 2337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Step 9:
5890 divided by 874 is 6 with a remainder of 646.
Put 6 as the next digit of the answer. 
Result so far: 15582.6
If we subtract 5244 from 5890, we get 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 10:
If we divide 6460 by 874, we get 7 and a remainder of 342.
The next digit of our result is 7. 
Result so far: 15582.67
If we subtract 6118 from 6460, we get 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Moving on to step 11:
874 goes into 3420 3 times with a remainder of 798.
Use 3 as the next digit of our solution. 
Result so far: 15582.673
If we take 2622 away from 3420, we end up with 798.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7980, and continue the process.

Advancing to step 12:
When dividing 7980 by 874, we get 9 with a remainder of 114.
Put 9 as the next digit of the answer. 
Result so far: 15582.6739
The remainder is 114 after subtracting 7866 from 7980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Advancing to step 13:
When dividing 1140 by 874, we get 1 with a remainder of 266.
Write down 1 as next digit of the result. 
Result so far: 15582.67391
If we take 874 away from 1140, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 14:
The number 874 fits into 2660 3 times, leaving a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 15582.673913
If we subtract 2622 from 2660, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 15:
If we divide 380 by 874, we get 0 and a remainder of 380.
Write down 0 as next digit of the result. 
Result so far: 15582.673913
Subtracting 0 from 380 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 16:
If we divide 3800 by 874, we get 4 and a remainder of 304.
The next digit of our result is 4. 
Result so far: 15582.67391304
Subtracting 3496 from 3800 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

The final outcome is 15582.67391304, with a leftover of 3.04e-07.
