We look at the division of 22378 by 23 
We're looking to find how many times 23 goes into 22378.

Going ahead to step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 23

Let's proceed to step 2:
23 goes into 22 0 times with a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Grab the next digit (3) from the dividend, add it to 22, then carry on: 223 / 23

On to step 3:
The number 23 fits into 223 9 times, leaving a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 16 after subtracting 207 from 223.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 23

Moving on to step 4:
23 goes into 167 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtract 161 from 167 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 23

Moving on to step 5:
The number 23 fits into 68 2 times, leaving a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 972.0
If we subtract 46 from 68, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 6:
If we divide 220 by 23, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 972.9
If we take 207 away from 220, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
23 goes into 130 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 972.95
Subtracting 115 from 130 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 972.956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
120 divided by 23 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 972.9565
Subtracting 115 from 120 leaves us 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 10:
23 goes into 50 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 972.95652
Subtract 46 from 50 to 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 11:
23 can be fit into 40 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 972.956521
Deduct 23 from 40 and we're left with 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 12:
170 divided by 23 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 972.9565217
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.

Moving on to step 13:
23 can be fit into 90 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 972.95652173
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.

The final result is 972.95652173 with a remainder of 2.1e-08.
