279743 ÷ 42 
The aim is to understand the frequency of 42 in 279743.

Going ahead to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 42

On to step 2:
When dividing 27 by 42, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 42

Moving on to step 3:
When dividing 279 by 42, we get 6 with a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 252 away from 279, we end up with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 42

On to step 4:
42 can be fit into 277 6 times, resulting in a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 66.0
The remainder is 25 after subtracting 252 from 277.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 42

Going ahead to step 5:
If we divide 254 by 42, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 666.0
If we subtract 252 from 254, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 42

Moving on to step 6:
42 goes into 23 0 times with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 6660.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
The number 42 fits into 230 5 times, leaving a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 6660.5
If we subtract 210 from 230, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 42 is 4 with a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 6660.54
The remainder is 32 after subtracting 168 from 200.
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 9:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 6660.547
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 6660.5476
Deduct 252 from 260 and we're left 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.

Advancing to step 11:
When dividing 80 by 42, we get 1 with a remainder of 38.
The next digit of our result is 1. 
Result so far: 6660.54761
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.

Moving on to step 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 6660.547619
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.

Advancing to step 13:
If we divide 20 by 42, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 6660.547619
If we take 0 away from 20, we end up 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.

Advancing to step 14:
42 goes into 200 4 times with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 6660.54761904
Deduct 168 from 200 and we're left 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.

The quotient of the division is 6660.54761904, and the remainder is 3.2e-08.
