We're dividing 77031 by 87 
The aim is to understand the frequency of 87 in 77031.

Let's proceed to step 1:
When dividing 7 by 87, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 87

On to step 2:
77 divided by 87 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (0) of the dividend behind the 77 and repeat the process: 770 / 87

Advancing to step 3:
The number 87 fits into 770 8 times, leaving a remainder of 74.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 74 after subtracting 696 from 770.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 87

On to step 4:
The number 87 fits into 743 8 times, leaving a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 47 after subtracting 696 from 743.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 87

Step 5:
When dividing 471 by 87, we get 5 with a remainder of 36.
The next digit of our result is 5. 
Result so far: 885.0
The remainder is 36 after subtracting 435 from 471.
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 6:
If we divide 360 by 87, we get 4 and a remainder of 12.
The next digit of our result is 4. 
Result so far: 885.4
Subtract 348 from 360 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
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: 885.41
Subtracting 87 from 120 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
If we divide 330 by 87, we get 3 and a remainder of 69.
The next digit of our result is 3. 
Result so far: 885.413
Subtract 261 from 330 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
If we divide 690 by 87, we get 7 and a remainder of 81.
The next digit of our result is 7. 
Result so far: 885.4137
Deduct 609 from 690 and we're left 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.

Let's proceed to step 10:
When dividing 810 by 87, we get 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 885.41379
The remainder is 27 after subtracting 783 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 11:
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: 885.413793
The remainder is 9 after subtracting 261 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
When dividing 90 by 87, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 885.4137931
If we take 87 away from 90, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
87 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 885.4137931
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 885.4137931, and the remainder is 3e-08.
