37155591 divided by 960 
The aim is to understand the frequency of 960 in 37155591.

Step 1:
When dividing 3 by 960, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 960

Going ahead to step 2:
960 goes into 37 0 times with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 960

Step 3:
If we divide 371 by 960, we get 0 and a remainder of 371.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 371 and we're left with 371.
Bring next digit (5) of the dividend behind the 371 and repeat the process: 3715 / 960

Moving on to step 4:
The number 960 fits into 3715 3 times, leaving a remainder of 835.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2880 from 3715, we get 835.
Include the next digit (5) from the dividend after 835, then repeat: 8355 / 960

On to step 5:
960 goes into 8355 8 times with a remainder of 675.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 675 after subtracting 7680 from 8355.
Bring next digit (5) of the dividend behind the 675 and repeat the process: 6755 / 960

Going ahead to step 6:
If we divide 6755 by 960, we get 7 and a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 387.0
The remainder is 35 after subtracting 6720 from 6755.
Grab the next digit (9) from the dividend, add it to 35, then carry on: 359 / 960

Moving on to step 7:
960 goes into 359 0 times with a remainder of 359.
Put 0 as the next digit of the answer. 
Result so far: 3870.0
Subtracting 0 from 359 leaves us with 359.
Bring next digit (1) of the dividend behind the 359 and repeat the process: 3591 / 960

Moving on to step 8:
When dividing 3591 by 960, we get 3 with a remainder of 711.
Put 3 as the next digit of the answer. 
Result so far: 38703.0
Subtracting 2880 from 3591 leaves us with 711.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7110, and continue the process.

Step 9:
If we divide 7110 by 960, we get 7 and a remainder of 390.
Record the quotient 7 as the next digit in the result. 
Result so far: 38703.7
Subtracting 6720 from 7110 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 10:
3900 divided by 960 is 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 38703.74
The remainder is 60 after subtracting 3840 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
When dividing 600 by 960, we get 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 38703.74
If we subtract 0 from 600, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 12:
The number 960 fits into 6000 6 times, leaving a remainder of 240.
Write down 6 as next digit of the result. 
Result so far: 38703.7406
If we subtract 5760 from 6000, we 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.

Step 13:
960 can be fit into 2400 2 times, resulting in a remainder of 480.
Put 2 as the next digit of the answer. 
Result so far: 38703.74062
If we take 1920 away from 2400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 14:
If we divide 4800 by 960, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 38703.740625
Deduct 4800 from 4800 and we're left 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.

Advancing to step 15:
If we divide 0 by 960, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38703.740625
Deduct 0 from 0 and we're left 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 16:
0 divided by 960 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 38703.740625
The remainder is 0 after subtracting 0 from 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 38703.740625 and a remainder of 0.0.
