Let's divide 456859 by 23
Let's see how many times 23 fits into 456859.

Moving on to step 1:
23 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 23

Moving on to step 2:
23 goes into 45 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 23 from 45 to get 22.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 23

Going ahead to step 3:
23 can be fit into 226 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 207 away from 226, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 23

Step 4:
23 can be fit into 198 8 times, resulting in a remainder of 14.
The next digit of our result is 8. 
Result so far: 198.0
If we subtract 184 from 198, we get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 23

Let's proceed to step 5:
When dividing 145 by 23, we get 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 1986.0
Subtracting 138 from 145 leaves us with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 23

Step 6:
79 divided by 23 is 3 with a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 19863.0
If we subtract 69 from 79, we 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.

Step 7:
23 can be fit into 100 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 19863.4
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.

Advancing to step 8:
23 goes into 80 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 19863.43
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.

Going ahead to step 9:
If we divide 110 by 23, we get 4 and a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 19863.434
If we take 92 away from 110, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
180 divided by 23 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 19863.4347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
190 divided by 23 is 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 19863.43478
Deduct 184 from 190 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
23 goes into 60 2 times with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 19863.434782
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 19863.4347826
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
The number 23 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 19863.4347826
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 19863.4347826 and a remainder of 2e-08.
