We're dividing 38403342 by 642 
The aim is to understand the frequency of 642 in 38403342.

Moving on to step 1:
3 divided by 642 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 642

Moving on to step 2:
If we divide 38 by 642, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 38 after subtracting 0 from 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 642

Step 3:
When dividing 384 by 642, we get 0 with a remainder of 384.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 384 leaves us with 384.
Append the next digit (0) from the dividend to 384 and continue with: 3840 / 642

Moving on to step 4:
3840 divided by 642 is 5 with a remainder of 630.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 3210 from 3840, we get 630.
Include the next digit (3) from the dividend after 630, then repeat: 6303 / 642

Going ahead to step 5:
642 goes into 6303 9 times with a remainder of 525.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtract 5778 from 6303 to get 525.
Take the next digit (3) from the dividend and append it to 525, then repeat: 5253 / 642

Step 6:
642 can be fit into 5253 8 times, resulting in a remainder of 117.
Put 8 as the next digit of the answer. 
Result so far: 598.0
Subtract 5136 from 5253 to get 117.
Include the next digit (4) from the dividend after 117, then repeat: 1174 / 642

Let's proceed to step 7:
If we divide 1174 by 642, we get 1 and a remainder of 532.
The number 1 becomes the next digit in our result. 
Result so far: 5981.0
The remainder is 532 after subtracting 642 from 1174.
Append the next digit (2) from the dividend to 532 and continue with: 5322 / 642

Advancing to step 8:
642 can be fit into 5322 8 times, resulting in a remainder of 186.
The next digit of our result is 8. 
Result so far: 59818.0
If we take 5136 away from 5322, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 9:
1860 divided by 642 is 2 with a remainder of 576.
The next digit of our result is 2. 
Result so far: 59818.2
If we take 1284 away from 1860, we end up with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Step 10:
If we divide 5760 by 642, we get 8 and a remainder of 624.
The number 8 becomes the next digit in our result. 
Result so far: 59818.28
Subtracting 5136 from 5760 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Let's proceed to step 11:
642 can be fit into 6240 9 times, resulting in a remainder of 462.
The next digit of our result is 9. 
Result so far: 59818.289
The remainder is 462 after subtracting 5778 from 6240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 12:
When dividing 4620 by 642, we get 7 with a remainder of 126.
The next digit of our result is 7. 
Result so far: 59818.2897
Subtracting 4494 from 4620 leaves us with 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 13:
1260 divided by 642 is 1 with a remainder of 618.
Use 1 as the next digit of our solution. 
Result so far: 59818.28971
Subtract 642 from 1260 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 14:
642 can be fit into 6180 9 times, resulting in a remainder of 402.
Write down 9 as next digit of the result. 
Result so far: 59818.289719
Subtracting 5778 from 6180 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 15:
The number 642 fits into 4020 6 times, leaving a remainder of 168.
Put 6 as the next digit of the answer. 
Result so far: 59818.2897196
If we subtract 3852 from 4020, 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.

Step 16:
1680 divided by 642 is 2 with a remainder of 396.
Write down 2 as next digit of the result. 
Result so far: 59818.28971962
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.

In conclusion, the division gives 59818.28971962 with a balance of 3.96e-07.
