142351 divided by 23 
We're looking to find how many times 23 goes into 142351.

Moving on to step 1:
23 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 23

On to step 2:
If we divide 14 by 23, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 23

On to step 3:
142 divided by 23 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 138 from 142, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 23

Moving on to step 4:
43 divided by 23 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 23 from 43 leaves us with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 23

Advancing to step 5:
205 divided by 23 is 8 with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 618.0
The remainder is 21 after subtracting 184 from 205.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 23

Going ahead to step 6:
211 divided by 23 is 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 6189.0
If we subtract 207 from 211, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 6189.1
Subtract 23 from 40 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 8:
23 goes into 170 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 6189.17
If we take 161 away from 170, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
23 goes into 90 3 times with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 6189.173
Deduct 69 from 90 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 6189.1739
Subtract 207 from 210 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 11:
30 divided by 23 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 6189.17391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
If we divide 70 by 23, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 6189.173913
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 6189.173913
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
When dividing 100 by 23, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 6189.17391304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 6189.17391304 with a remaining 8e-09.
