We divide 433958 by 87
The aim is to understand the frequency of 87 in 433958.

Going ahead to step 1:
87 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 87

On 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
If we take 0 away from 43, we end up with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 87

Step 3:
If we divide 433 by 87, we get 4 and a remainder of 85.
The next digit of our result is 4. 
Result so far: 4.0
If we take 348 away from 433, we end up with 85.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 87

Moving on to step 4:
859 divided by 87 is 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 783 away from 859, we end up with 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 87

Going ahead to step 5:
765 divided by 87 is 8 with a remainder of 69.
Write down 8 as next digit of the result. 
Result so far: 498.0
Subtract 696 from 765 to get 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 87

Moving on to step 6:
If we divide 698 by 87, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 4988.0
The remainder is 2 after subtracting 696 from 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
20 divided by 87 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4988.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
87 goes into 200 2 times with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 4988.02
Subtract 174 from 200 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 87 is 2 with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 4988.022
If we take 174 away from 260, we end up with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The quotient of the division is 4988.022, and the remainder is 0.0086.
