We're dividing 23163885 by 42 
We want to divide 23163885 by 42.

On to step 1:
If we divide 2 by 42, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 42

On to step 2:
42 goes into 23 0 times with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 42

Step 3:
42 goes into 231 5 times with a remainder of 21.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 21 after subtracting 210 from 231.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 42

On to step 4:
42 can be fit into 216 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 55.0
If we take 210 away from 216, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 42

On to step 5:
42 goes into 63 1 times with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 551.0
The remainder is 21 after subtracting 42 from 63.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 42

On to step 6:
The number 42 fits into 218 5 times, leaving a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 5515.0
If we take 210 away from 218, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 42

Step 7:
The number 42 fits into 88 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 55152.0
If we take 84 away from 88, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 42

Going ahead to step 8:
If we divide 45 by 42, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 551521.0
Subtract 42 from 45 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
When dividing 30 by 42, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 551521.0
If we take 0 away from 30, 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:
The number 42 fits into 300 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 551521.07
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.

Step 11:
42 goes into 60 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 551521.071
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.

Going ahead to step 12:
42 goes into 180 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 551521.0714
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:
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: 551521.07142
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.

Going ahead to step 14:
42 goes into 360 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 551521.071428
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.

Step 15:
When dividing 240 by 42, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 551521.0714285
Deduct 210 from 240 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.

Moving on to step 16:
300 divided by 42 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 551521.07142857
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.

The final outcome is 551521.07142857, with a leftover of 6e-09.
