Let's divide 38004240 by 874
The aim is to understand the frequency of 874 in 38004240.

On to step 1:
If we divide 3 by 874, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 874

On to step 2:
When dividing 38 by 874, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 874

Let's proceed to step 3:
874 goes into 380 0 times with a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 380, we get 380.
Append the next digit (0) from the dividend to 380 and continue with: 3800 / 874

Moving on to step 4:
If we divide 3800 by 874, we get 4 and a remainder of 304.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3496 from 3800, we get 304.
Include the next digit (4) from the dividend after 304, then repeat: 3044 / 874

Advancing to step 5:
The number 874 fits into 3044 3 times, leaving a remainder of 422.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 2622 from 3044 and we're left with 422.
Include the next digit (2) from the dividend after 422, then repeat: 4222 / 874

Advancing to step 6:
874 can be fit into 4222 4 times, resulting in a remainder of 726.
Put 4 as the next digit of the answer. 
Result so far: 434.0
Subtracting 3496 from 4222 leaves us with 726.
Include the next digit (4) from the dividend after 726, then repeat: 7264 / 874

Advancing to step 7:
When dividing 7264 by 874, we get 8 with a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 4348.0
If we subtract 6992 from 7264, we get 272.
Fetch the next digit (0) from the dividend, attach it to 272 and continue: 2720 / 874

Moving on to step 8:
If we divide 2720 by 874, we get 3 and a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 43483.0
If we take 2622 away from 2720, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
874 can be fit into 980 1 times, resulting in a remainder of 106.
The number 1 becomes the next digit in our result. 
Result so far: 43483.1
If we take 874 away from 980, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 10:
874 goes into 1060 1 times with a remainder of 186.
Write down 1 as next digit of the result. 
Result so far: 43483.11
If we take 874 away from 1060, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

After the division, we end up with 43483.11 and a remainder of 0.186.
