373175 divided by 428 
The aim is to understand the frequency of 428 in 373175.

Going ahead to step 1:
The number 428 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 428

On to step 2:
If we divide 37 by 428, we get 0 and a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Fetch the next digit (3) from the dividend, attach it to 37 and continue: 373 / 428

Moving on to step 3:
428 goes into 373 0 times with a remainder of 373.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 373 leaves us with 373.
Take the next digit (1) from the dividend and append it to 373, then repeat: 3731 / 428

On to step 4:
If we divide 3731 by 428, we get 8 and a remainder of 307.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 3424 from 3731 leaves us with 307.
Fetch the next digit (7) from the dividend, attach it to 307 and continue: 3077 / 428

Let's proceed to step 5:
428 can be fit into 3077 7 times, resulting in a remainder of 81.
Use 7 as the next digit of our solution. 
Result so far: 87.0
If we take 2996 away from 3077, we end up with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 428

Moving on to step 6:
428 can be fit into 815 1 times, resulting in a remainder of 387.
Record the quotient 1 as the next digit in the result. 
Result so far: 871.0
Subtracting 428 from 815 leaves us with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Advancing to step 7:
The number 428 fits into 3870 9 times, leaving a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 871.9
If we take 3852 away from 3870, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
428 can be fit into 180 0 times, resulting in a remainder of 180.
Put 0 as the next digit of the answer. 
Result so far: 871.9
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
If we divide 1800 by 428, we get 4 and a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 871.904
The remainder is 88 after subtracting 1712 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 10:
The number 428 fits into 880 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 871.9042
Subtract 856 from 880 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
If we divide 240 by 428, we get 0 and a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 871.9042
If we take 0 away from 240, we end up with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 12:
428 goes into 2400 5 times with a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 871.904205
If we take 2140 away from 2400, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 13:
If we divide 2600 by 428, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 871.9042056
If we take 2568 away from 2600, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
428 goes into 320 0 times with a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 871.9042056
If we take 0 away from 320, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 871.9042056, with a leftover of 3.2e-07.
