We're dividing 12012173 by 442 
The aim is to understand the frequency of 442 in 12012173.

On to step 1:
When dividing 1 by 442, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 442

Let's proceed to step 2:
442 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 442

On to step 3:
If we divide 120 by 442, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 120 to get 120.
Take the next digit (1) from the dividend and append it to 120, then repeat: 1201 / 442

Let's proceed to step 4:
442 can be fit into 1201 2 times, resulting in a remainder of 317.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 884 from 1201 to get 317.
Bring next digit (2) of the dividend behind the 317 and repeat the process: 3172 / 442

On to step 5:
442 can be fit into 3172 7 times, resulting in a remainder of 78.
The next digit of our result is 7. 
Result so far: 27.0
If we take 3094 away from 3172, we end up with 78.
Append the next digit (1) from the dividend to 78 and continue with: 781 / 442

On to step 6:
442 goes into 781 1 times with a remainder of 339.
Put 1 as the next digit of the answer. 
Result so far: 271.0
Deduct 442 from 781 and we're left with 339.
Append the next digit (7) from the dividend to 339 and continue with: 3397 / 442

On to step 7:
3397 divided by 442 is 7 with a remainder of 303.
Record the quotient 7 as the next digit in the result. 
Result so far: 2717.0
Subtracting 3094 from 3397 leaves us with 303.
Bring next digit (3) of the dividend behind the 303 and repeat the process: 3033 / 442

Going ahead to step 8:
442 goes into 3033 6 times with a remainder of 381.
Record the quotient 6 as the next digit in the result. 
Result so far: 27176.0
Subtract 2652 from 3033 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 9:
The number 442 fits into 3810 8 times, leaving a remainder of 274.
Write down 8 as next digit of the result. 
Result so far: 27176.8
Subtracting 3536 from 3810 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 10:
442 can be fit into 2740 6 times, resulting in a remainder of 88.
Put 6 as the next digit of the answer. 
Result so far: 27176.86
Subtracting 2652 from 2740 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
The number 442 fits into 880 1 times, leaving a remainder of 438.
Put 1 as the next digit of the answer. 
Result so far: 27176.861
If we take 442 away from 880, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

Advancing to step 12:
When dividing 4380 by 442, we get 9 with a remainder of 402.
The number 9 becomes the next digit in our result. 
Result so far: 27176.8619
Subtracting 3978 from 4380 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

On to step 13:
If we divide 4020 by 442, we get 9 and a remainder of 42.
The next digit of our result is 9. 
Result so far: 27176.86199
If we take 3978 away from 4020, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 27176.86199 with a remainder of 4.2e-05.
