We're dividing 420124 by 23 
Our goal is to divide 420124 by 23.

Let's proceed to step 1:
23 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 23

Going ahead to step 2:
If we divide 42 by 23, we get 1 and a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
If we take 23 away from 42, we end up with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 23

On to step 3:
When dividing 190 by 23, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 184 from 190 and we're left with 6.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 23

Step 4:
When dividing 61 by 23, we get 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
Subtracting 46 from 61 leaves us with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 23

Going ahead to step 5:
When dividing 152 by 23, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 1826.0
If we subtract 138 from 152, we get 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 23

Let's proceed to step 6:
When dividing 144 by 23, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 18266.0
If we subtract 138 from 144, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
60 divided by 23 is 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 18266.2
The remainder is 14 after subtracting 46 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
23 goes into 140 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 18266.26
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 18266.26
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 18266.2608
Deduct 184 from 200 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
160 divided by 23 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 18266.26086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 18266.260869
Deduct 207 from 220 and we're left 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.

Step 13:
23 can be fit into 130 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 18266.2608695
Deduct 115 from 130 and we're left 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.

On to step 14:
23 can be fit into 150 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 18266.26086956
Deduct 138 from 150 and we're left 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.

After the division, we end up with 18266.26086956 and a remainder of 1.2e-08.
