87580472 ÷ 964 
The aim is to understand the frequency of 964 in 87580472.

Going ahead to step 1:
If we divide 8 by 964, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 964

On to step 2:
87 divided by 964 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Take the next digit (5) from the dividend and append it to 87, then repeat: 875 / 964

Moving on to step 3:
If we divide 875 by 964, we get 0 and a remainder of 875.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 875, we end up with 875.
Include the next digit (8) from the dividend after 875, then repeat: 8758 / 964

Advancing to step 4:
964 goes into 8758 9 times with a remainder of 82.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 8676 from 8758 and we're left with 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 964

On to step 5:
If we divide 820 by 964, we get 0 and a remainder of 820.
The next digit of our result is 0. 
Result so far: 90.0
If we take 0 away from 820, we end up with 820.
Take the next digit (4) from the dividend and append it to 820, then repeat: 8204 / 964

Advancing to step 6:
The number 964 fits into 8204 8 times, leaving a remainder of 492.
Use 8 as the next digit of our solution. 
Result so far: 908.0
Subtract 7712 from 8204 to get 492.
Fetch the next digit (7) from the dividend, attach it to 492 and continue: 4927 / 964

Let's proceed to step 7:
The number 964 fits into 4927 5 times, leaving a remainder of 107.
The next digit of our result is 5. 
Result so far: 9085.0
Subtract 4820 from 4927 to get 107.
Grab the next digit (2) from the dividend, add it to 107, then carry on: 1072 / 964

Moving on to step 8:
964 goes into 1072 1 times with a remainder of 108.
The next digit of our result is 1. 
Result so far: 90851.0
The remainder is 108 after subtracting 964 from 1072.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 9:
1080 divided by 964 is 1 with a remainder of 116.
The next digit of our result is 1. 
Result so far: 90851.1
The remainder is 116 after subtracting 964 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
1160 divided by 964 is 1 with a remainder of 196.
Record the quotient 1 as the next digit in the result. 
Result so far: 90851.11
If we subtract 964 from 1160, we get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

The final result is 90851.11 with a remainder of 0.196.
