We look at the division of 221874 by 42 
We're looking to find how many times 42 goes into 221874.

Step 1:
42 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 42

Advancing to step 2:
The number 42 fits into 22 0 times, leaving a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Append the next digit (1) from the dividend to 22 and continue with: 221 / 42

Let's proceed to step 3:
42 goes into 221 5 times with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 11 after subtracting 210 from 221.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 42

Moving on to step 4:
42 goes into 118 2 times with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
The remainder is 34 after subtracting 84 from 118.
Append the next digit (7) from the dividend to 34 and continue with: 347 / 42

On to step 5:
When dividing 347 by 42, we get 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 528.0
If we take 336 away from 347, we end up with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 42

Step 6:
The number 42 fits into 114 2 times, leaving a remainder of 30.
The next digit of our result is 2. 
Result so far: 5282.0
Deduct 84 from 114 and we're left 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.

Going ahead to step 7:
If we divide 300 by 42, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 5282.7
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
If we divide 60 by 42, we get 1 and a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 5282.71
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
42 goes into 180 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 5282.714
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 10:
42 can be fit into 120 2 times, resulting in a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 5282.7142
If we subtract 84 from 120, we get 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 11:
360 divided by 42 is 8 with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 5282.71428
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.

On to step 12:
240 divided by 42 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 5282.714285
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 13:
If we divide 300 by 42, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 5282.7142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
If we divide 60 by 42, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 5282.71428571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 5282.71428571, with a leftover of 1.8e-08.
