We look at the division of 1887829 by 874 
The aim is to understand the frequency of 874 in 1887829.

Step 1:
874 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 874

Advancing to step 2:
874 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 874

Moving on to step 3:
874 goes into 188 0 times with a remainder of 188.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 188 to get 188.
Grab the next digit (7) from the dividend, add it to 188, then carry on: 1887 / 874

Step 4:
874 can be fit into 1887 2 times, resulting in a remainder of 139.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1748 from 1887 to get 139.
Grab the next digit (8) from the dividend, add it to 139, then carry on: 1398 / 874

Let's proceed to step 5:
874 can be fit into 1398 1 times, resulting in a remainder of 524.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 874 from 1398 and we're left with 524.
Bring next digit (2) of the dividend behind the 524 and repeat the process: 5242 / 874

Step 6:
If we divide 5242 by 874, we get 5 and a remainder of 872.
Put 5 as the next digit of the answer. 
Result so far: 215.0
The remainder is 872 after subtracting 4370 from 5242.
Grab the next digit (9) from the dividend, add it to 872, then carry on: 8729 / 874

On to step 7:
The number 874 fits into 8729 9 times, leaving a remainder of 863.
Put 9 as the next digit of the answer. 
Result so far: 2159.0
The remainder is 863 after subtracting 7866 from 8729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8630, and continue the process.

Moving on to step 8:
874 can be fit into 8630 9 times, resulting in a remainder of 764.
Write down 9 as next digit of the result. 
Result so far: 2159.9
Subtract 7866 from 8630 to get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Going ahead to step 9:
If we divide 7640 by 874, we get 8 and a remainder of 648.
Put 8 as the next digit of the answer. 
Result so far: 2159.98
Deduct 6992 from 7640 and we're left with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Advancing to step 10:
874 goes into 6480 7 times with a remainder of 362.
The next digit of our result is 7. 
Result so far: 2159.987
Subtracting 6118 from 6480 leaves us with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

On to step 11:
When dividing 3620 by 874, we get 4 with a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 2159.9874
The remainder is 124 after subtracting 3496 from 3620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 12:
874 can be fit into 1240 1 times, resulting in a remainder of 366.
Put 1 as the next digit of the answer. 
Result so far: 2159.98741
If we subtract 874 from 1240, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Going ahead to step 13:
When dividing 3660 by 874, we get 4 with a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 2159.987414
If we subtract 3496 from 3660, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 14:
874 can be fit into 1640 1 times, resulting in a remainder of 766.
Write down 1 as next digit of the result. 
Result so far: 2159.9874141
Subtract 874 from 1640 to get 766.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7660, and continue the process.

Going ahead to step 15:
7660 divided by 874 is 8 with a remainder of 668.
The next digit of our result is 8. 
Result so far: 2159.98741418
Deduct 6992 from 7660 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

After the division, we end up with 2159.98741418 and a remainder of 6.68e-07.
