21854928 ÷ 42 
We're looking to find how many times 42 goes into 21854928.

On to step 1:
The number 42 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 42

On to step 2:
42 can be fit into 21 0 times, resulting in a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 42

Step 3:
218 divided by 42 is 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 210 from 218 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 42

Going ahead to step 4:
42 goes into 85 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 84 from 85 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 42

Moving on to step 5:
14 divided by 42 is 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 520.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 42

Moving on to step 6:
When dividing 149 by 42, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 5203.0
Deduct 126 from 149 and we're left with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 42

Moving on to step 7:
When dividing 232 by 42, we get 5 with a remainder of 22.
The next digit of our result is 5. 
Result so far: 52035.0
If we take 210 away from 232, we end up with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 42

Step 8:
If we divide 228 by 42, we get 5 and a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 520355.0
The remainder is 18 after subtracting 210 from 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
180 divided by 42 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 520355.4
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.

Let's proceed to step 10:
If we divide 120 by 42, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 520355.42
Subtract 84 from 120 to 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.

Going ahead to step 11:
42 goes into 360 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 520355.428
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.

Going ahead to step 12:
240 divided by 42 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 520355.4285
Subtract 210 from 240 to 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.

Going ahead to step 13:
300 divided by 42 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 520355.42857
Deduct 294 from 300 and we're left 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 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 520355.428571
If we subtract 42 from 60, we 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.

Going ahead to step 15:
42 goes into 180 4 times with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 520355.4285714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 16:
If we divide 120 by 42, we get 2 and a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 520355.42857142
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.

Our division results in 520355.42857142 with a remaining 3.6e-08.
