75341394 ÷ 428 
The aim is to understand the frequency of 428 in 75341394.

Moving on to step 1:
428 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 428

Let's proceed to step 2:
75 divided by 428 is 0 with a remainder of 75.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Append the next digit (3) from the dividend to 75 and continue with: 753 / 428

On to step 3:
When dividing 753 by 428, we get 1 with a remainder of 325.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 428 from 753 leaves us with 325.
Bring next digit (4) of the dividend behind the 325 and repeat the process: 3254 / 428

On to step 4:
The number 428 fits into 3254 7 times, leaving a remainder of 258.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 258 after subtracting 2996 from 3254.
Include the next digit (1) from the dividend after 258, then repeat: 2581 / 428

Step 5:
428 goes into 2581 6 times with a remainder of 13.
The next digit of our result is 6. 
Result so far: 176.0
If we take 2568 away from 2581, we end up with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 428

On to step 6:
The number 428 fits into 133 0 times, leaving a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 1760.0
If we take 0 away from 133, we end up with 133.
Append the next digit (9) from the dividend to 133 and continue with: 1339 / 428

Step 7:
If we divide 1339 by 428, we get 3 and a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 17603.0
If we take 1284 away from 1339, we end up with 55.
Append the next digit (4) from the dividend to 55 and continue with: 554 / 428

On to step 8:
When dividing 554 by 428, we get 1 with a remainder of 126.
Record the quotient 1 as the next digit in the result. 
Result so far: 176031.0
If we subtract 428 from 554, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 9:
428 goes into 1260 2 times with a remainder of 404.
The next digit of our result is 2. 
Result so far: 176031.2
Subtract 856 from 1260 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Let's proceed to step 10:
The number 428 fits into 4040 9 times, leaving a remainder of 188.
Use 9 as the next digit of our solution. 
Result so far: 176031.29
Subtracting 3852 from 4040 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 11:
If we divide 1880 by 428, we get 4 and a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 176031.294
If we subtract 1712 from 1880, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 12:
The number 428 fits into 1680 3 times, leaving a remainder of 396.
The number 3 becomes the next digit in our result. 
Result so far: 176031.2943
Subtract 1284 from 1680 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Going ahead to step 13:
The number 428 fits into 3960 9 times, leaving a remainder of 108.
Use 9 as the next digit of our solution. 
Result so far: 176031.29439
If we take 3852 away from 3960, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 14:
1080 divided by 428 is 2 with a remainder of 224.
Write down 2 as next digit of the result. 
Result so far: 176031.294392
If we subtract 856 from 1080, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 15:
2240 divided by 428 is 5 with a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 176031.2943925
If we take 2140 away from 2240, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 16:
428 can be fit into 1000 2 times, resulting in a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 176031.29439252
If we subtract 856 from 1000, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final result is 176031.29439252 with a remainder of 1.44e-07.
