We divide 373857 by 42
The aim is to understand the frequency of 42 in 373857.

Step 1:
When dividing 3 by 42, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 42

Step 2:
If we divide 37 by 42, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 42

Going ahead to step 3:
If we divide 373 by 42, we get 8 and a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 336 from 373 and we're left with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 42

Let's proceed to step 4:
42 can be fit into 378 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtracting 378 from 378 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 42

Step 5:
If we divide 5 by 42, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 890.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 42

Let's proceed to step 6:
57 divided by 42 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 8901.0
If we subtract 42 from 57, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
42 goes into 150 3 times with a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 8901.3
Subtracting 126 from 150 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
42 goes into 240 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 8901.35
If we subtract 210 from 240, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
300 divided by 42 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 8901.357
Subtracting 294 from 300 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 8901.3571
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
When dividing 180 by 42, we get 4 with a remainder of 12.
The next digit of our result is 4. 
Result so far: 8901.35714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 8901.357142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
42 goes into 360 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 8901.3571428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
240 divided by 42 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 8901.35714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 8901.35714285, and the remainder is 3e-08.
