We're dividing 16344347 by 428 
The aim is to understand the frequency of 428 in 16344347.

On to step 1:
When dividing 1 by 428, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 428

Let's proceed to step 2:
If we divide 16 by 428, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 428

Advancing to step 3:
The number 428 fits into 163 0 times, leaving a remainder of 163.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 163 to get 163.
Grab the next digit (4) from the dividend, add it to 163, then carry on: 1634 / 428

Advancing to step 4:
When dividing 1634 by 428, we get 3 with a remainder of 350.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 1284 from 1634 to get 350.
Bring next digit (4) of the dividend behind the 350 and repeat the process: 3504 / 428

On to step 5:
428 can be fit into 3504 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 80 after subtracting 3424 from 3504.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 428

Going ahead to step 6:
803 divided by 428 is 1 with a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 381.0
Subtracting 428 from 803 leaves us with 375.
Fetch the next digit (4) from the dividend, attach it to 375 and continue: 3754 / 428

Moving on to step 7:
If we divide 3754 by 428, we get 8 and a remainder of 330.
The next digit of our result is 8. 
Result so far: 3818.0
Deduct 3424 from 3754 and we're left with 330.
Grab the next digit (7) from the dividend, add it to 330, then carry on: 3307 / 428

Going ahead to step 8:
428 can be fit into 3307 7 times, resulting in a remainder of 311.
Record the quotient 7 as the next digit in the result. 
Result so far: 38187.0
If we take 2996 away from 3307, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 9:
If we divide 3110 by 428, we get 7 and a remainder of 114.
The next digit of our result is 7. 
Result so far: 38187.7
If we take 2996 away from 3110, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Let's proceed to step 10:
If we divide 1140 by 428, we get 2 and a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 38187.72
If we subtract 856 from 1140, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
428 goes into 2840 6 times with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 38187.726
If we subtract 2568 from 2840, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 12:
If we divide 2720 by 428, we get 6 and a remainder of 152.
The next digit of our result is 6. 
Result so far: 38187.7266
Deduct 2568 from 2720 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

After the division, we end up with 38187.7266 and a remainder of 0.00152.
