78407132 divided by 522 
The aim is to understand the frequency of 522 in 78407132.

Step 1:
The number 522 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 522

Let's proceed to step 2:
522 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (4) from the dividend after 78, then repeat: 784 / 522

Advancing to step 3:
If we divide 784 by 522, we get 1 and a remainder of 262.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 522 from 784 leaves us with 262.
Bring next digit (0) of the dividend behind the 262 and repeat the process: 2620 / 522

On to step 4:
522 can be fit into 2620 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 10 after subtracting 2610 from 2620.
Append the next digit (7) from the dividend to 10 and continue with: 107 / 522

Moving on to step 5:
107 divided by 522 is 0 with a remainder of 107.
The next digit of our result is 0. 
Result so far: 150.0
Deduct 0 from 107 and we're left with 107.
Fetch the next digit (1) from the dividend, attach it to 107 and continue: 1071 / 522

On to step 6:
When dividing 1071 by 522, we get 2 with a remainder of 27.
Record the quotient 2 as the next digit in the result. 
Result so far: 1502.0
Subtracting 1044 from 1071 leaves us with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 522

Going ahead to step 7:
273 divided by 522 is 0 with a remainder of 273.
The next digit of our result is 0. 
Result so far: 15020.0
Subtract 0 from 273 to get 273.
Append the next digit (2) from the dividend to 273 and continue with: 2732 / 522

On to step 8:
522 can be fit into 2732 5 times, resulting in a remainder of 122.
The next digit of our result is 5. 
Result so far: 150205.0
If we subtract 2610 from 2732, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 9:
522 goes into 1220 2 times with a remainder of 176.
The number 2 becomes the next digit in our result. 
Result so far: 150205.2
If we subtract 1044 from 1220, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 10:
If we divide 1760 by 522, we get 3 and a remainder of 194.
The next digit of our result is 3. 
Result so far: 150205.23
Subtract 1566 from 1760 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

On to step 11:
When dividing 1940 by 522, we get 3 with a remainder of 374.
The next digit of our result is 3. 
Result so far: 150205.233
If we subtract 1566 from 1940, we get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

The quotient of the division is 150205.233, and the remainder is 0.0374.
