124727 ÷ 42 
The aim is to understand the frequency of 42 in 124727.

Let's proceed to step 1:
The number 42 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 42

On to step 2:
If we divide 12 by 42, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 42

Moving on to step 3:
If we divide 124 by 42, we get 2 and a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 84 from 124, we get 40.
Bring next digit (7) of the dividend behind the 40 and repeat the process: 407 / 42

Going ahead to step 4:
The number 42 fits into 407 9 times, leaving a remainder of 29.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 378 from 407 leaves us with 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 42

Going ahead to step 5:
If we divide 292 by 42, we get 6 and a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 296.0
The remainder is 40 after subtracting 252 from 292.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 42

Step 6:
407 divided by 42 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 2969.0
Subtract 378 from 407 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 7:
If we divide 290 by 42, we get 6 and a remainder of 38.
Write down 6 as next digit of the result. 
Result so far: 2969.6
Subtracting 252 from 290 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
If we divide 380 by 42, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 2969.69
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 42, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 2969.69
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
42 goes into 200 4 times with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 2969.6904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
If we divide 320 by 42, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 2969.69047
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 42 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2969.690476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
The number 42 fits into 80 1 times, leaving a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 2969.6904761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
380 divided by 42 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 2969.69047619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 2969.69047619, and the remainder is 2e-09.
