69435863 divided by 964 
The aim is to understand the frequency of 964 in 69435863.

Moving on to step 1:
When dividing 6 by 964, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 964

Let's proceed to step 2:
If we divide 69 by 964, we get 0 and a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Append the next digit (4) from the dividend to 69 and continue with: 694 / 964

On to step 3:
964 goes into 694 0 times with a remainder of 694.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 694 to get 694.
Bring next digit (3) of the dividend behind the 694 and repeat the process: 6943 / 964

On to step 4:
964 can be fit into 6943 7 times, resulting in a remainder of 195.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 6748 from 6943 to get 195.
Grab the next digit (5) from the dividend, add it to 195, then carry on: 1955 / 964

Advancing to step 5:
When dividing 1955 by 964, we get 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 1928 from 1955 and we're left with 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 964

On to step 6:
If we divide 278 by 964, we get 0 and a remainder of 278.
The number 0 becomes the next digit in our result. 
Result so far: 720.0
If we subtract 0 from 278, we get 278.
Include the next digit (6) from the dividend after 278, then repeat: 2786 / 964

Let's proceed to step 7:
If we divide 2786 by 964, we get 2 and a remainder of 858.
The number 2 becomes the next digit in our result. 
Result so far: 7202.0
If we take 1928 away from 2786, we end up with 858.
Bring next digit (3) of the dividend behind the 858 and repeat the process: 8583 / 964

Step 8:
8583 divided by 964 is 8 with a remainder of 871.
Use 8 as the next digit of our solution. 
Result so far: 72028.0
Subtract 7712 from 8583 to get 871.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8710, and continue the process.

Moving on to step 9:
8710 divided by 964 is 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 72028.9
The remainder is 34 after subtracting 8676 from 8710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
When dividing 340 by 964, we get 0 with a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 72028.9
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 11:
3400 divided by 964 is 3 with a remainder of 508.
Use 3 as the next digit of our solution. 
Result so far: 72028.903
Subtract 2892 from 3400 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 12:
964 goes into 5080 5 times with a remainder of 260.
Use 5 as the next digit of our solution. 
Result so far: 72028.9035
Deduct 4820 from 5080 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
The number 964 fits into 2600 2 times, leaving a remainder of 672.
Use 2 as the next digit of our solution. 
Result so far: 72028.90352
If we subtract 1928 from 2600, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 14:
964 goes into 6720 6 times with a remainder of 936.
The number 6 becomes the next digit in our result. 
Result so far: 72028.903526
Deduct 5784 from 6720 and we're left with 936.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9360, and continue the process.

Advancing to step 15:
The number 964 fits into 9360 9 times, leaving a remainder of 684.
Use 9 as the next digit of our solution. 
Result so far: 72028.9035269
If we take 8676 away from 9360, we end up with 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 16:
6840 divided by 964 is 7 with a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 72028.90352697
Subtract 6748 from 6840 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 72028.90352697 with a remainder of 9.2e-08.
