We're dividing 87171811 by 962 
The aim is to understand the frequency of 962 in 87171811.

Step 1:
If we divide 8 by 962, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 962

On to step 2:
The number 962 fits into 87 0 times, leaving a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Fetch the next digit (1) from the dividend, attach it to 87 and continue: 871 / 962

Let's proceed to step 3:
962 can be fit into 871 0 times, resulting in a remainder of 871.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 871 after subtracting 0 from 871.
Take the next digit (7) from the dividend and append it to 871, then repeat: 8717 / 962

Step 4:
962 goes into 8717 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 8658 from 8717 and we're left with 59.
Take the next digit (1) from the dividend and append it to 59, then repeat: 591 / 962

Advancing to step 5:
The number 962 fits into 591 0 times, leaving a remainder of 591.
The next digit of our result is 0. 
Result so far: 90.0
Deduct 0 from 591 and we're left with 591.
Bring next digit (8) of the dividend behind the 591 and repeat the process: 5918 / 962

Moving on to step 6:
5918 divided by 962 is 6 with a remainder of 146.
Put 6 as the next digit of the answer. 
Result so far: 906.0
Subtract 5772 from 5918 to get 146.
Fetch the next digit (1) from the dividend, attach it to 146 and continue: 1461 / 962

Moving on to step 7:
962 can be fit into 1461 1 times, resulting in a remainder of 499.
Write down 1 as next digit of the result. 
Result so far: 9061.0
If we take 962 away from 1461, we end up with 499.
Include the next digit (1) from the dividend after 499, then repeat: 4991 / 962

Let's proceed to step 8:
The number 962 fits into 4991 5 times, leaving a remainder of 181.
The number 5 becomes the next digit in our result. 
Result so far: 90615.0
If we take 4810 away from 4991, we end up with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 9:
1810 divided by 962 is 1 with a remainder of 848.
Record the quotient 1 as the next digit in the result. 
Result so far: 90615.1
If we take 962 away from 1810, we end up with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Advancing to step 10:
If we divide 8480 by 962, we get 8 and a remainder of 784.
Write down 8 as next digit of the result. 
Result so far: 90615.18
If we subtract 7696 from 8480, we get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Going ahead to step 11:
962 can be fit into 7840 8 times, resulting in a remainder of 144.
The number 8 becomes the next digit in our result. 
Result so far: 90615.188
Subtract 7696 from 7840 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 90615.188 with a remaining 0.0144.
