Let's divide 73148942 by 428
The aim is to understand the frequency of 428 in 73148942.

On to step 1:
7 divided by 428 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 428

On to step 2:
The number 428 fits into 73 0 times, leaving a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 428

Advancing to step 3:
428 can be fit into 731 1 times, resulting in a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 428 from 731 leaves us with 303.
Include the next digit (4) from the dividend after 303, then repeat: 3034 / 428

On to step 4:
When dividing 3034 by 428, we get 7 with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 2996 away from 3034, we end up with 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 428

Advancing to step 5:
When dividing 388 by 428, we get 0 with a remainder of 388.
Record the quotient 0 as the next digit in the result. 
Result so far: 170.0
Subtracting 0 from 388 leaves us with 388.
Bring next digit (9) of the dividend behind the 388 and repeat the process: 3889 / 428

Let's proceed to step 6:
3889 divided by 428 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 1709.0
The remainder is 37 after subtracting 3852 from 3889.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 428

On to step 7:
428 goes into 374 0 times with a remainder of 374.
Record the quotient 0 as the next digit in the result. 
Result so far: 17090.0
The remainder is 374 after subtracting 0 from 374.
Include the next digit (2) from the dividend after 374, then repeat: 3742 / 428

Step 8:
If we divide 3742 by 428, we get 8 and a remainder of 318.
Record the quotient 8 as the next digit in the result. 
Result so far: 170908.0
Subtracting 3424 from 3742 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 9:
The number 428 fits into 3180 7 times, leaving a remainder of 184.
Put 7 as the next digit of the answer. 
Result so far: 170908.7
If we subtract 2996 from 3180, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 10:
1840 divided by 428 is 4 with a remainder of 128.
Write down 4 as next digit of the result. 
Result so far: 170908.74
Deduct 1712 from 1840 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

On to step 11:
1280 divided by 428 is 2 with a remainder of 424.
The number 2 becomes the next digit in our result. 
Result so far: 170908.742
If we subtract 856 from 1280, we get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

On to step 12:
428 can be fit into 4240 9 times, resulting in a remainder of 388.
Record the quotient 9 as the next digit in the result. 
Result so far: 170908.7429
If we subtract 3852 from 4240, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 13:
If we divide 3880 by 428, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 170908.74299
Subtracting 3852 from 3880 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.

In conclusion, the division gives 170908.74299 with a balance of 2.8e-05.
