We divide 64559932 by 428
The aim is to understand the frequency of 428 in 64559932.

Moving on to step 1:
When dividing 6 by 428, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 428

Going ahead to step 2:
428 goes into 64 0 times with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 428

Going ahead to step 3:
428 goes into 645 1 times with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 428 away from 645, we end up with 217.
Include the next digit (5) from the dividend after 217, then repeat: 2175 / 428

Going ahead to step 4:
2175 divided by 428 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 2140 from 2175 to get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 428

Step 5:
The number 428 fits into 359 0 times, leaving a remainder of 359.
Write down 0 as next digit of the result. 
Result so far: 150.0
Deduct 0 from 359 and we're left with 359.
Fetch the next digit (9) from the dividend, attach it to 359 and continue: 3599 / 428

Let's proceed to step 6:
The number 428 fits into 3599 8 times, leaving a remainder of 175.
The next digit of our result is 8. 
Result so far: 1508.0
If we take 3424 away from 3599, we end up with 175.
Fetch the next digit (3) from the dividend, attach it to 175 and continue: 1753 / 428

Moving on to step 7:
428 can be fit into 1753 4 times, resulting in a remainder of 41.
Record the quotient 4 as the next digit in the result. 
Result so far: 15084.0
If we take 1712 away from 1753, we end up with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 428

Going ahead to step 8:
412 divided by 428 is 0 with a remainder of 412.
Write down 0 as next digit of the result. 
Result so far: 150840.0
Subtracting 0 from 412 leaves us with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Let's proceed to step 9:
If we divide 4120 by 428, we get 9 and a remainder of 268.
Put 9 as the next digit of the answer. 
Result so far: 150840.9
If we take 3852 away from 4120, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Let's proceed to step 10:
The number 428 fits into 2680 6 times, leaving a remainder of 112.
The number 6 becomes the next digit in our result. 
Result so far: 150840.96
If we subtract 2568 from 2680, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 11:
When dividing 1120 by 428, we get 2 with a remainder of 264.
The next digit of our result is 2. 
Result so far: 150840.962
Subtracting 856 from 1120 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 12:
The number 428 fits into 2640 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 150840.9626
Subtracting 2568 from 2640 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 13:
428 goes into 720 1 times with a remainder of 292.
Put 1 as the next digit of the answer. 
Result so far: 150840.96261
Subtract 428 from 720 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 14:
The number 428 fits into 2920 6 times, leaving a remainder of 352.
Use 6 as the next digit of our solution. 
Result so far: 150840.962616
Subtracting 2568 from 2920 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Let's proceed to step 15:
428 can be fit into 3520 8 times, resulting in a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 150840.9626168
Subtract 3424 from 3520 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 16:
960 divided by 428 is 2 with a remainder of 104.
Use 2 as the next digit of our solution. 
Result so far: 150840.96261682
Subtracting 856 from 960 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 150840.96261682, and the remainder is 1.04e-07.
