We're dividing 52471582 by 642 
The aim is to understand the frequency of 642 in 52471582.

Moving on to step 1:
642 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 642

Let's proceed to step 2:
When dividing 52 by 642, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 642

Moving on to step 3:
The number 642 fits into 524 0 times, leaving a remainder of 524.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 524, we get 524.
Bring next digit (7) of the dividend behind the 524 and repeat the process: 5247 / 642

Moving on to step 4:
When dividing 5247 by 642, we get 8 with a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 5136 from 5247 and we're left with 111.
Bring next digit (1) of the dividend behind the 111 and repeat the process: 1111 / 642

Let's proceed to step 5:
When dividing 1111 by 642, we get 1 with a remainder of 469.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 469 after subtracting 642 from 1111.
Include the next digit (5) from the dividend after 469, then repeat: 4695 / 642

Moving on to step 6:
642 can be fit into 4695 7 times, resulting in a remainder of 201.
Use 7 as the next digit of our solution. 
Result so far: 817.0
Subtracting 4494 from 4695 leaves us with 201.
Append the next digit (8) from the dividend to 201 and continue with: 2018 / 642

Advancing to step 7:
If we divide 2018 by 642, we get 3 and a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 8173.0
Subtract 1926 from 2018 to get 92.
Append the next digit (2) from the dividend to 92 and continue with: 922 / 642

Step 8:
642 goes into 922 1 times with a remainder of 280.
The number 1 becomes the next digit in our result. 
Result so far: 81731.0
Deduct 642 from 922 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 9:
When dividing 2800 by 642, we get 4 with a remainder of 232.
Use 4 as the next digit of our solution. 
Result so far: 81731.4
The remainder is 232 after subtracting 2568 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 10:
When dividing 2320 by 642, we get 3 with a remainder of 394.
The next digit of our result is 3. 
Result so far: 81731.43
If we take 1926 away from 2320, we end up with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Going ahead to step 11:
The number 642 fits into 3940 6 times, leaving a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 81731.436
If we take 3852 away from 3940, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
880 divided by 642 is 1 with a remainder of 238.
Write down 1 as next digit of the result. 
Result so far: 81731.4361
Deduct 642 from 880 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 13:
642 can be fit into 2380 3 times, resulting in a remainder of 454.
Write down 3 as next digit of the result. 
Result so far: 81731.43613
The remainder is 454 after subtracting 1926 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Let's proceed to step 14:
642 can be fit into 4540 7 times, resulting in a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 81731.436137
Subtract 4494 from 4540 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 15:
642 can be fit into 460 0 times, resulting in a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 81731.436137
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 16:
642 can be fit into 4600 7 times, resulting in a remainder of 106.
Put 7 as the next digit of the answer. 
Result so far: 81731.43613707
If we subtract 4494 from 4600, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

After the division, we end up with 81731.43613707 and a remainder of 1.06e-07.
