Let's divide 431676 by 87
The aim is to understand the frequency of 87 in 431676.

Let's proceed to step 1:
The number 87 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 87

Advancing to step 2:
87 can be fit into 43 0 times, resulting in a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Append the next digit (1) from the dividend to 43 and continue with: 431 / 87

Advancing to step 3:
431 divided by 87 is 4 with a remainder of 83.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 348 away from 431, we end up with 83.
Grab the next digit (6) from the dividend, add it to 83, then carry on: 836 / 87

Step 4:
87 can be fit into 836 9 times, resulting in a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 53 after subtracting 783 from 836.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 87

Moving on to step 5:
87 goes into 537 6 times with a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 496.0
Subtracting 522 from 537 leaves us with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 87

Step 6:
87 can be fit into 156 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 4961.0
The remainder is 69 after subtracting 87 from 156.
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 7:
When dividing 690 by 87, we get 7 with a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 4961.7
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 8:
If we divide 810 by 87, we get 9 and a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 4961.79
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.

Going ahead to step 9:
87 can be fit into 270 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 4961.793
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.

Moving on to step 10:
87 can be fit into 90 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 4961.7931
Subtracting 87 from 90 leaves us 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 11:
87 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 4961.7931
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
When dividing 300 by 87, we get 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 4961.793103
If we take 261 away from 300, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
The number 87 fits into 390 4 times, leaving a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4961.7931034
Deduct 348 from 390 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 4961.79310344
Subtract 348 from 420 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 4961.79310344, with a leftover of 7.2e-08.
