We look at the division of 78114192 by 964 
The aim is to understand the frequency of 964 in 78114192.

Advancing to step 1:
964 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 964

Moving on to step 2:
964 goes into 78 0 times with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 964

Advancing to step 3:
The number 964 fits into 781 0 times, leaving a remainder of 781.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 781 after subtracting 0 from 781.
Fetch the next digit (1) from the dividend, attach it to 781 and continue: 7811 / 964

Step 4:
964 goes into 7811 8 times with a remainder of 99.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 7712 away from 7811, we end up with 99.
Include the next digit (4) from the dividend after 99, then repeat: 994 / 964

On to step 5:
994 divided by 964 is 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 964 from 994 leaves us with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 964

On to step 6:
301 divided by 964 is 0 with a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 810.0
If we subtract 0 from 301, we get 301.
Fetch the next digit (9) from the dividend, attach it to 301 and continue: 3019 / 964

Going ahead to step 7:
964 goes into 3019 3 times with a remainder of 127.
The number 3 becomes the next digit in our result. 
Result so far: 8103.0
Subtracting 2892 from 3019 leaves us with 127.
Take the next digit (2) from the dividend and append it to 127, then repeat: 1272 / 964

Going ahead to step 8:
When dividing 1272 by 964, we get 1 with a remainder of 308.
The number 1 becomes the next digit in our result. 
Result so far: 81031.0
The remainder is 308 after subtracting 964 from 1272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 9:
3080 divided by 964 is 3 with a remainder of 188.
The next digit of our result is 3. 
Result so far: 81031.3
If we subtract 2892 from 3080, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 10:
964 can be fit into 1880 1 times, resulting in a remainder of 916.
Record the quotient 1 as the next digit in the result. 
Result so far: 81031.31
Deduct 964 from 1880 and we're left with 916.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9160, and continue the process.

Step 11:
9160 divided by 964 is 9 with a remainder of 484.
Record the quotient 9 as the next digit in the result. 
Result so far: 81031.319
If we take 8676 away from 9160, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

On to step 12:
When dividing 4840 by 964, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 81031.3195
Deduct 4820 from 4840 and we're left with 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 13:
The number 964 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 81031.3195
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 14:
964 can be fit into 2000 2 times, resulting in a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 81031.319502
Deduct 1928 from 2000 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 15:
720 divided by 964 is 0 with a remainder of 720.
Use 0 as the next digit of our solution. 
Result so far: 81031.319502
Subtracting 0 from 720 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 16:
The number 964 fits into 7200 7 times, leaving a remainder of 452.
Write down 7 as next digit of the result. 
Result so far: 81031.31950207
If we take 6748 away from 7200, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

The quotient of the division is 81031.31950207, and the remainder is 4.52e-07.
