We divide 157470 by 42
The aim is to understand the frequency of 42 in 157470.

Moving on to step 1:
42 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 42

Step 2:
If we divide 15 by 42, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 42

Moving on to step 3:
42 goes into 157 3 times with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 126 from 157 to get 31.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 42

Step 4:
42 goes into 314 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 294 from 314 and we're left with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 42

Step 5:
If we divide 207 by 42, we get 4 and a remainder of 39.
The next digit of our result is 4. 
Result so far: 374.0
The remainder is 39 after subtracting 168 from 207.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 42

Going ahead to step 6:
The number 42 fits into 390 9 times, leaving a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 3749.0
If we subtract 378 from 390, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 42, we get 2 and a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3749.2
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 42, we get 8 and a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 3749.28
If we subtract 336 from 360, we get 24.
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 9:
The number 42 fits into 240 5 times, leaving a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 3749.285
If we take 210 away from 240, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
When dividing 300 by 42, we get 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 3749.2857
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.

Let's proceed to step 11:
If we divide 60 by 42, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 3749.28571
If we take 42 away from 60, we end up 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 12:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 3749.285714
If we take 168 away from 180, we end up 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.

Step 13:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 3749.2857142
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.

Step 14:
42 can be fit into 360 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 3749.28571428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 3749.28571428 with a remaining 2.4e-08.
