43970 ÷ 23 
Let's see how many times 23 fits into 43970.

Moving on to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 23

Advancing to step 2:
When dividing 43 by 23, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 23 from 43 leaves us with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 23

Moving on to step 3:
When dividing 209 by 23, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 207 from 209 to get 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 23

Going ahead to step 4:
27 divided by 23 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Subtracting 23 from 27 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 23

Advancing to step 5:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1911.0
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.

Moving on to step 6:
23 goes into 170 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 1911.7
Subtract 161 from 170 to get 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 7:
90 divided by 23 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 1911.73
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.

Step 8:
If we divide 210 by 23, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1911.739
If we take 207 away from 210, we end up with 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 9:
23 goes into 30 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1911.7391
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.

Going ahead to step 10:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1911.73913
Subtracting 69 from 70 leaves us 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.

Moving on to step 11:
The number 23 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 1911.73913
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.

Going ahead to step 12:
100 divided by 23 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 1911.7391304
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.

On to step 13:
If we divide 80 by 23, we get 3 and a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 1911.73913043
If we take 69 away from 80, we end up 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.

The final outcome is 1911.73913043, with a leftover of 1.1e-08.
