We divide 75553 by 66
The aim is to understand the frequency of 66 in 75553.

Step 1:
66 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 66

Let's proceed to step 2:
66 can be fit into 75 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 66 from 75 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 66

Let's proceed to step 3:
95 divided by 66 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 66 from 95 to get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 66

Going ahead to step 4:
295 divided by 66 is 4 with a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
If we take 264 away from 295, we end up with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 66

Let's proceed to step 5:
The number 66 fits into 313 4 times, leaving a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 1144.0
Subtracting 264 from 313 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 6:
When dividing 490 by 66, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 1144.7
If we subtract 462 from 490, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
66 goes into 280 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1144.74
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
If we divide 160 by 66, we get 2 and a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 1144.742
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 9:
66 goes into 280 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1144.7424
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
160 divided by 66 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 1144.74242
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
If we divide 280 by 66, we get 4 and a remainder of 16.
The next digit of our result is 4. 
Result so far: 1144.742424
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
66 can be fit into 160 2 times, resulting in a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1144.7424242
Subtract 132 from 160 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
66 can be fit into 280 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1144.74242424
Subtract 264 from 280 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1144.74242424 and a remainder of 1.6e-08.
