428070 ÷ 23 
Our goal is to divide 428070 by 23.

Moving on to step 1:
4 divided by 23 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 23

Let's proceed to step 2:
23 can be fit into 42 1 times, resulting in a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 23 from 42 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 23

Step 3:
23 goes into 198 8 times with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 184 from 198 and we're left with 14.
Bring next digit (0) of the dividend behind the 14 and repeat the process: 140 / 23

Moving on to step 4:
23 goes into 140 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 186.0
The remainder is 2 after subtracting 138 from 140.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 23

Step 5:
If we divide 27 by 23, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1861.0
If we take 23 away from 27, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 23

On to step 6:
If we divide 40 by 23, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 18611.0
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 18611.7
Subtracting 161 from 170 leaves us 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.

On to step 8:
23 goes into 90 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 18611.73
Subtracting 69 from 90 leaves us 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.

Advancing to step 9:
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: 18611.739
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.

On to step 10:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 18611.7391
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.

Let's proceed to step 11:
23 goes into 70 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 18611.73913
If we take 69 away from 70, we end up 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.

Advancing to step 12:
10 divided by 23 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 18611.73913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 18611.7391304
Deduct 92 from 100 and we're left 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.

Let's proceed to step 14:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 18611.73913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 18611.73913043 and a remainder of 1.1e-08.
