16621164 divided by 960 
The aim is to understand the frequency of 960 in 16621164.

Step 1:
The number 960 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 960

Step 2:
960 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 960

Step 3:
960 can be fit into 166 0 times, resulting in a remainder of 166.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 166, we get 166.
Grab the next digit (2) from the dividend, add it to 166, then carry on: 1662 / 960

On to step 4:
960 can be fit into 1662 1 times, resulting in a remainder of 702.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 960 from 1662 leaves us with 702.
Fetch the next digit (1) from the dividend, attach it to 702 and continue: 7021 / 960

Going ahead to step 5:
960 can be fit into 7021 7 times, resulting in a remainder of 301.
Write down 7 as next digit of the result. 
Result so far: 17.0
Subtracting 6720 from 7021 leaves us with 301.
Fetch the next digit (1) from the dividend, attach it to 301 and continue: 3011 / 960

Going ahead to step 6:
If we divide 3011 by 960, we get 3 and a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 173.0
Subtracting 2880 from 3011 leaves us with 131.
Bring next digit (6) of the dividend behind the 131 and repeat the process: 1316 / 960

On to step 7:
The number 960 fits into 1316 1 times, leaving a remainder of 356.
Use 1 as the next digit of our solution. 
Result so far: 1731.0
Subtracting 960 from 1316 leaves us with 356.
Fetch the next digit (4) from the dividend, attach it to 356 and continue: 3564 / 960

Going ahead to step 8:
960 can be fit into 3564 3 times, resulting in a remainder of 684.
Record the quotient 3 as the next digit in the result. 
Result so far: 17313.0
Subtract 2880 from 3564 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Moving on to step 9:
6840 divided by 960 is 7 with a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 17313.7
Deduct 6720 from 6840 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
If we divide 1200 by 960, we get 1 and a remainder of 240.
Write down 1 as next digit of the result. 
Result so far: 17313.71
Subtract 960 from 1200 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 11:
If we divide 2400 by 960, we get 2 and a remainder of 480.
The number 2 becomes the next digit in our result. 
Result so far: 17313.712
The remainder is 480 after subtracting 1920 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
960 goes into 4800 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 17313.7125
If we take 4800 away from 4800, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 13:
When dividing 0 by 960, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17313.7125
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 14:
960 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17313.7125
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 17313.7125 and a remainder of 0.0.
