378569 ÷ 23 
Our goal is to divide 378569 by 23.

Step 1:
When dividing 3 by 23, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 23

Step 2:
The number 23 fits into 37 1 times, leaving a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 23 from 37 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 23

Going ahead to step 3:
The number 23 fits into 148 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 138 from 148, we get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 23

Step 4:
23 can be fit into 105 4 times, resulting in a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 164.0
The remainder is 13 after subtracting 92 from 105.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 23

Step 5:
23 goes into 136 5 times with a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 1645.0
Deduct 115 from 136 and we're left with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 23

Going ahead to step 6:
23 goes into 219 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 16459.0
If we take 207 away from 219, 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 7:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 16459.5
Deduct 115 from 120 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
When dividing 50 by 23, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 16459.52
Subtracting 46 from 50 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
23 goes into 40 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 16459.521
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.

Moving on to step 10:
23 goes into 170 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 16459.5217
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.

Going ahead to step 11:
23 goes into 90 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 16459.52173
If we subtract 69 from 90, we 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.

Advancing to step 12:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 16459.521739
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.

Advancing to step 13:
If we divide 30 by 23, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 16459.5217391
Subtract 23 from 30 to get 7.
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 14:
If we divide 70 by 23, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 16459.52173913
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.

In conclusion, the division gives 16459.52173913 with a balance of 1e-09.
