64165768 divided by 891 
The aim is to understand the frequency of 891 in 64165768.

Step 1:
891 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 891

On to step 2:
The number 891 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 891

Advancing to step 3:
The number 891 fits into 641 0 times, leaving a remainder of 641.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 641, we get 641.
Include the next digit (6) from the dividend after 641, then repeat: 6416 / 891

Advancing to step 4:
891 can be fit into 6416 7 times, resulting in a remainder of 179.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 179 after subtracting 6237 from 6416.
Append the next digit (5) from the dividend to 179 and continue with: 1795 / 891

Advancing to step 5:
891 goes into 1795 2 times with a remainder of 13.
The next digit of our result is 2. 
Result so far: 72.0
Deduct 1782 from 1795 and we're left with 13.
Grab the next digit (7) from the dividend, add it to 13, then carry on: 137 / 891

Moving on to step 6:
When dividing 137 by 891, we get 0 with a remainder of 137.
The number 0 becomes the next digit in our result. 
Result so far: 720.0
If we take 0 away from 137, we end up with 137.
Append the next digit (6) from the dividend to 137 and continue with: 1376 / 891

Going ahead to step 7:
891 can be fit into 1376 1 times, resulting in a remainder of 485.
Use 1 as the next digit of our solution. 
Result so far: 7201.0
If we subtract 891 from 1376, we get 485.
Bring next digit (8) of the dividend behind the 485 and repeat the process: 4858 / 891

On to step 8:
The number 891 fits into 4858 5 times, leaving a remainder of 403.
Put 5 as the next digit of the answer. 
Result so far: 72015.0
Deduct 4455 from 4858 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Going ahead to step 9:
891 can be fit into 4030 4 times, resulting in a remainder of 466.
Write down 4 as next digit of the result. 
Result so far: 72015.4
If we subtract 3564 from 4030, we get 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

On to step 10:
The number 891 fits into 4660 5 times, leaving a remainder of 205.
Use 5 as the next digit of our solution. 
Result so far: 72015.45
If we subtract 4455 from 4660, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 11:
2050 divided by 891 is 2 with a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 72015.452
Subtracting 1782 from 2050 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 12:
2680 divided by 891 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 72015.4523
Subtract 2673 from 2680 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
70 divided by 891 is 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 72015.4523
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
The number 891 fits into 700 0 times, leaving a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 72015.4523
Subtract 0 from 700 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

In conclusion, the division gives 72015.4523 with a balance of 7e-05.
