81155135 ÷ 960 
The aim is to understand the frequency of 960 in 81155135.

On to step 1:
The number 960 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 960

Step 2:
960 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 960

Let's proceed to step 3:
960 can be fit into 811 0 times, resulting in a remainder of 811.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 811 leaves us with 811.
Bring next digit (5) of the dividend behind the 811 and repeat the process: 8115 / 960

Advancing to step 4:
When dividing 8115 by 960, we get 8 with a remainder of 435.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 7680 from 8115, we get 435.
Include the next digit (5) from the dividend after 435, then repeat: 4355 / 960

Moving on to step 5:
The number 960 fits into 4355 4 times, leaving a remainder of 515.
Write down 4 as next digit of the result. 
Result so far: 84.0
If we subtract 3840 from 4355, we get 515.
Bring next digit (1) of the dividend behind the 515 and repeat the process: 5151 / 960

On to step 6:
The number 960 fits into 5151 5 times, leaving a remainder of 351.
Write down 5 as next digit of the result. 
Result so far: 845.0
The remainder is 351 after subtracting 4800 from 5151.
Grab the next digit (3) from the dividend, add it to 351, then carry on: 3513 / 960

Advancing to step 7:
3513 divided by 960 is 3 with a remainder of 633.
Put 3 as the next digit of the answer. 
Result so far: 8453.0
If we take 2880 away from 3513, we end up with 633.
Bring next digit (5) of the dividend behind the 633 and repeat the process: 6335 / 960

Moving on to step 8:
6335 divided by 960 is 6 with a remainder of 575.
The number 6 becomes the next digit in our result. 
Result so far: 84536.0
Subtract 5760 from 6335 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 9:
960 goes into 5750 5 times with a remainder of 950.
The next digit of our result is 5. 
Result so far: 84536.5
Subtract 4800 from 5750 to get 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9500, and continue the process.

Moving on to step 10:
9500 divided by 960 is 9 with a remainder of 860.
Use 9 as the next digit of our solution. 
Result so far: 84536.59
Deduct 8640 from 9500 and we're left with 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8600, and continue the process.

On to step 11:
960 can be fit into 8600 8 times, resulting in a remainder of 920.
The number 8 becomes the next digit in our result. 
Result so far: 84536.598
The remainder is 920 after subtracting 7680 from 8600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9200, and continue the process.

On to step 12:
9200 divided by 960 is 9 with a remainder of 560.
Use 9 as the next digit of our solution. 
Result so far: 84536.5989
Subtracting 8640 from 9200 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

On to step 13:
960 can be fit into 5600 5 times, resulting in a remainder of 800.
The number 5 becomes the next digit in our result. 
Result so far: 84536.59895
The remainder is 800 after subtracting 4800 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 14:
960 goes into 8000 8 times with a remainder of 320.
Record the quotient 8 as the next digit in the result. 
Result so far: 84536.598958
Subtract 7680 from 8000 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

On to step 15:
3200 divided by 960 is 3 with a remainder of 320.
The number 3 becomes the next digit in our result. 
Result so far: 84536.5989583
The remainder is 320 after subtracting 2880 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 16:
960 goes into 3200 3 times with a remainder of 320.
Put 3 as the next digit of the answer. 
Result so far: 84536.59895833
The remainder is 320 after subtracting 2880 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Our division results in 84536.59895833 with a remaining 3.2e-07.
