We divide 31992 by 87
The aim is to understand the frequency of 87 in 31992.

Let's proceed to step 1:
87 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 87

Step 2:
87 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (9) of the dividend behind the 31 and repeat the process: 319 / 87

Step 3:
87 can be fit into 319 3 times, resulting in a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 261 from 319 and we're left with 58.
Fetch the next digit (9) from the dividend, attach it to 58 and continue: 589 / 87

Moving on to step 4:
When dividing 589 by 87, we get 6 with a remainder of 67.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 522 from 589, we get 67.
Take the next digit (2) from the dividend and append it to 67, then repeat: 672 / 87

Step 5:
When dividing 672 by 87, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 367.0
If we take 609 away from 672, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 6:
87 can be fit into 630 7 times, resulting in a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 367.7
Deduct 609 from 630 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
87 can be fit into 210 2 times, resulting in a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 367.72
The remainder is 36 after subtracting 174 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
When dividing 360 by 87, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 367.724
The remainder is 12 after subtracting 348 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
The number 87 fits into 120 1 times, leaving a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 367.7241
The remainder is 33 after subtracting 87 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 10:
When dividing 330 by 87, we get 3 with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 367.72413
If we take 261 away from 330, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 11:
87 can be fit into 690 7 times, resulting in a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 367.724137
Subtracting 609 from 690 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 12:
87 can be fit into 810 9 times, resulting in a remainder of 27.
The next digit of our result is 9. 
Result so far: 367.7241379
Subtract 783 from 810 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 13:
If we divide 270 by 87, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 367.72413793
If we subtract 261 from 270, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Our division results in 367.72413793 with a remaining 9e-09.
