357898 divided by 42 
The aim is to understand the frequency of 42 in 357898.

Moving on to step 1:
42 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 42

Let's proceed to step 2:
42 goes into 35 0 times with a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 42

Going ahead to step 3:
42 goes into 357 8 times with a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 336 from 357 leaves us with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 42

Let's proceed to step 4:
If we divide 218 by 42, we get 5 and a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 210 from 218 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 42

Moving on to step 5:
89 divided by 42 is 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 852.0
Subtract 84 from 89 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 42

Step 6:
58 divided by 42 is 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 8521.0
Subtract 42 from 58 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
42 goes into 160 3 times with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 8521.3
Subtracting 126 from 160 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 8:
If we divide 340 by 42, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8521.38
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
42 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8521.38
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
The number 42 fits into 400 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 8521.3809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
If we divide 220 by 42, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 8521.38095
If we take 210 away from 220, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
When dividing 100 by 42, we get 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 8521.380952
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
42 can be fit into 160 3 times, resulting in a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 8521.3809523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
The number 42 fits into 340 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 8521.38095238
Deduct 336 from 340 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 8521.38095238 with a balance of 4e-09.
