46378579 ÷ 23 
Our goal is to divide 46378579 by 23.

Step 1:
When dividing 4 by 23, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 23

Let's proceed to step 2:
When dividing 46 by 23, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 46 from 46 to get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 23

Step 3:
If we divide 3 by 23, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 23

Going ahead to step 4:
37 divided by 23 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 201.0
Deduct 23 from 37 and we're left with 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 23

Moving on to step 5:
23 goes into 148 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 2016.0
Subtracting 138 from 148 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 23

Step 6:
105 divided by 23 is 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 20164.0
Subtract 92 from 105 to get 13.
Take the next digit (7) from the dividend and append it to 13, then repeat: 137 / 23

Step 7:
When dividing 137 by 23, we get 5 with a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 201645.0
If we subtract 115 from 137, we get 22.
Grab the next digit (9) from the dividend, add it to 22, then carry on: 229 / 23

Step 8:
If we divide 229 by 23, we get 9 and a remainder of 22.
Put 9 as the next digit of the answer. 
Result so far: 2016459.0
Deduct 207 from 229 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
23 can be fit into 220 9 times, resulting in a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 2016459.9
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 2016459.95
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.

Advancing to step 11:
The number 23 fits into 150 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 2016459.956
Subtract 138 from 150 to get 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 12:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2016459.9565
If we take 115 away from 120, we end up 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.

Let's proceed to step 13:
When dividing 50 by 23, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2016459.95652
If we subtract 46 from 50, 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 14:
The number 23 fits into 40 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 2016459.956521
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.

On to step 15:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 2016459.9565217
Deduct 161 from 170 and we're left 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.

Advancing to step 16:
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: 2016459.95652173
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 quotient of the division is 2016459.95652173, and the remainder is 2.1e-08.
