87981140 divided by 234 
The aim is to understand the frequency of 234 in 87981140.

Moving on to step 1:
If we divide 8 by 234, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 234

On to step 2:
The number 234 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 234

Advancing to step 3:
If we divide 879 by 234, we get 3 and a remainder of 177.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 702 from 879, we get 177.
Bring next digit (8) of the dividend behind the 177 and repeat the process: 1778 / 234

Advancing to step 4:
The number 234 fits into 1778 7 times, leaving a remainder of 140.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 1638 away from 1778, we end up with 140.
Include the next digit (1) from the dividend after 140, then repeat: 1401 / 234

Going ahead to step 5:
The number 234 fits into 1401 5 times, leaving a remainder of 231.
Write down 5 as next digit of the result. 
Result so far: 375.0
The remainder is 231 after subtracting 1170 from 1401.
Append the next digit (1) from the dividend to 231 and continue with: 2311 / 234

On to step 6:
The number 234 fits into 2311 9 times, leaving a remainder of 205.
Use 9 as the next digit of our solution. 
Result so far: 3759.0
Subtracting 2106 from 2311 leaves us with 205.
Append the next digit (4) from the dividend to 205 and continue with: 2054 / 234

On to step 7:
The number 234 fits into 2054 8 times, leaving a remainder of 182.
Write down 8 as next digit of the result. 
Result so far: 37598.0
Subtract 1872 from 2054 to get 182.
Bring next digit (0) of the dividend behind the 182 and repeat the process: 1820 / 234

Let's proceed to step 8:
234 goes into 1820 7 times with a remainder of 182.
The next digit of our result is 7. 
Result so far: 375987.0
The remainder is 182 after subtracting 1638 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 9:
234 goes into 1820 7 times with a remainder of 182.
The number 7 becomes the next digit in our result. 
Result so far: 375987.7
If we take 1638 away from 1820, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 10:
234 can be fit into 1820 7 times, resulting in a remainder of 182.
Write down 7 as next digit of the result. 
Result so far: 375987.77
If we take 1638 away from 1820, we end up with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

The final result is 375987.77 with a remainder of 0.182.
