Let's divide 42738 by 23
We want to figure out the number of times 42738 can be divided by 23.

Advancing to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 23

Moving on to step 2:
When dividing 42 by 23, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 23 from 42 and we're left with 19.
Grab the next digit (7) from the dividend, add it to 19, then carry on: 197 / 23

On to step 3:
When dividing 197 by 23, we get 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 184 from 197 and we're left with 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 23

Going ahead to step 4:
The number 23 fits into 133 5 times, leaving a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
Subtracting 115 from 133 leaves us with 18.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 23

Advancing to step 5:
23 goes into 188 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1858.0
If we subtract 184 from 188, 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.

Going ahead to step 6:
When dividing 40 by 23, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1858.1
If we subtract 23 from 40, we 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.

Advancing to step 7:
170 divided by 23 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1858.17
The remainder is 9 after subtracting 161 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
If we divide 90 by 23, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 1858.173
Subtract 69 from 90 to get 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 9:
23 goes into 210 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 1858.1739
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
When dividing 30 by 23, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1858.17391
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.

Moving on to step 11:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1858.173913
The remainder is 1 after subtracting 69 from 70.
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 12:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1858.173913
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 13:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1858.17391304
Subtracting 92 from 100 leaves us 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.

The final outcome is 1858.17391304, with a leftover of 8e-09.
