7851031 ÷ 874 
The aim is to understand the frequency of 874 in 7851031.

Advancing to step 1:
7 divided by 874 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 874

Advancing to step 2:
If we divide 78 by 874, we get 0 and a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 874

On to step 3:
785 divided by 874 is 0 with a remainder of 785.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 785 to get 785.
Include the next digit (1) from the dividend after 785, then repeat: 7851 / 874

Let's proceed to step 4:
7851 divided by 874 is 8 with a remainder of 859.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 6992 from 7851 leaves us with 859.
Take the next digit (0) from the dividend and append it to 859, then repeat: 8590 / 874

Let's proceed to step 5:
874 can be fit into 8590 9 times, resulting in a remainder of 724.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we subtract 7866 from 8590, we get 724.
Include the next digit (3) from the dividend after 724, then repeat: 7243 / 874

Let's proceed to step 6:
874 goes into 7243 8 times with a remainder of 251.
Put 8 as the next digit of the answer. 
Result so far: 898.0
If we take 6992 away from 7243, we end up with 251.
Fetch the next digit (1) from the dividend, attach it to 251 and continue: 2511 / 874

On to step 7:
874 can be fit into 2511 2 times, resulting in a remainder of 763.
The next digit of our result is 2. 
Result so far: 8982.0
If we subtract 1748 from 2511, we get 763.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7630, and continue the process.

Advancing to step 8:
When dividing 7630 by 874, we get 8 with a remainder of 638.
Put 8 as the next digit of the answer. 
Result so far: 8982.8
Deduct 6992 from 7630 and we're left with 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 9:
The number 874 fits into 6380 7 times, leaving a remainder of 262.
The number 7 becomes the next digit in our result. 
Result so far: 8982.87
If we take 6118 away from 6380, we end up with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 10:
If we divide 2620 by 874, we get 2 and a remainder of 872.
Write down 2 as next digit of the result. 
Result so far: 8982.872
Deduct 1748 from 2620 and we're left with 872.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8720, and continue the process.

Moving on to step 11:
The number 874 fits into 8720 9 times, leaving a remainder of 854.
Put 9 as the next digit of the answer. 
Result so far: 8982.8729
Subtracting 7866 from 8720 leaves us with 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Advancing to step 12:
If we divide 8540 by 874, we get 9 and a remainder of 674.
Write down 9 as next digit of the result. 
Result so far: 8982.87299
Subtract 7866 from 8540 to get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

In conclusion, the division gives 8982.87299 with a balance of 0.000674.
