61535509 ÷ 964 
The aim is to understand the frequency of 964 in 61535509.

Let's proceed to step 1:
964 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 964

On to step 2:
964 can be fit into 61 0 times, resulting in a remainder of 61.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 61 and we're left with 61.
Append the next digit (5) from the dividend to 61 and continue with: 615 / 964

Advancing to step 3:
If we divide 615 by 964, we get 0 and a remainder of 615.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 615, we get 615.
Include the next digit (3) from the dividend after 615, then repeat: 6153 / 964

Going ahead to step 4:
If we divide 6153 by 964, we get 6 and a remainder of 369.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 5784 from 6153 to get 369.
Include the next digit (5) from the dividend after 369, then repeat: 3695 / 964

Advancing to step 5:
The number 964 fits into 3695 3 times, leaving a remainder of 803.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 2892 from 3695 to get 803.
Append the next digit (5) from the dividend to 803 and continue with: 8035 / 964

Going ahead to step 6:
The number 964 fits into 8035 8 times, leaving a remainder of 323.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
The remainder is 323 after subtracting 7712 from 8035.
Append the next digit (0) from the dividend to 323 and continue with: 3230 / 964

Moving on to step 7:
When dividing 3230 by 964, we get 3 with a remainder of 338.
Write down 3 as next digit of the result. 
Result so far: 6383.0
If we subtract 2892 from 3230, we get 338.
Take the next digit (9) from the dividend and append it to 338, then repeat: 3389 / 964

Step 8:
If we divide 3389 by 964, we get 3 and a remainder of 497.
Write down 3 as next digit of the result. 
Result so far: 63833.0
If we subtract 2892 from 3389, we get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 9:
4970 divided by 964 is 5 with a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 63833.5
The remainder is 150 after subtracting 4820 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
If we divide 1500 by 964, we get 1 and a remainder of 536.
Write down 1 as next digit of the result. 
Result so far: 63833.51
Subtract 964 from 1500 to get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 11:
5360 divided by 964 is 5 with a remainder of 540.
Record the quotient 5 as the next digit in the result. 
Result so far: 63833.515
Deduct 4820 from 5360 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 12:
When dividing 5400 by 964, we get 5 with a remainder of 580.
Use 5 as the next digit of our solution. 
Result so far: 63833.5155
Subtracting 4820 from 5400 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

The quotient of the division is 63833.5155, and the remainder is 0.0058.
