We look at the division of 23454428 by 489 
We want to figure out the number of times 23454428 can be divided by 489.

Going ahead to step 1:
When dividing 2 by 489, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 489

Advancing to step 2:
489 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 489

Let's proceed to step 3:
489 can be fit into 234 0 times, resulting in a remainder of 234.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 234 and we're left with 234.
Bring next digit (5) of the dividend behind the 234 and repeat the process: 2345 / 489

Moving on to step 4:
The number 489 fits into 2345 4 times, leaving a remainder of 389.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1956 from 2345, we get 389.
Bring next digit (4) of the dividend behind the 389 and repeat the process: 3894 / 489

Step 5:
The number 489 fits into 3894 7 times, leaving a remainder of 471.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 3423 away from 3894, we end up with 471.
Take the next digit (4) from the dividend and append it to 471, then repeat: 4714 / 489

Advancing to step 6:
If we divide 4714 by 489, we get 9 and a remainder of 313.
Use 9 as the next digit of our solution. 
Result so far: 479.0
The remainder is 313 after subtracting 4401 from 4714.
Bring next digit (2) of the dividend behind the 313 and repeat the process: 3132 / 489

Moving on to step 7:
489 goes into 3132 6 times with a remainder of 198.
Put 6 as the next digit of the answer. 
Result so far: 4796.0
The remainder is 198 after subtracting 2934 from 3132.
Include the next digit (8) from the dividend after 198, then repeat: 1988 / 489

Advancing to step 8:
1988 divided by 489 is 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 47964.0
If we take 1956 away from 1988, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
The number 489 fits into 320 0 times, leaving a remainder of 320.
Put 0 as the next digit of the answer. 
Result so far: 47964.0
If we subtract 0 from 320, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 10:
489 can be fit into 3200 6 times, resulting in a remainder of 266.
Put 6 as the next digit of the answer. 
Result so far: 47964.06
Deduct 2934 from 3200 and we're left with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 11:
The number 489 fits into 2660 5 times, leaving a remainder of 215.
Record the quotient 5 as the next digit in the result. 
Result so far: 47964.065
Subtract 2445 from 2660 to get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 12:
489 goes into 2150 4 times with a remainder of 194.
The next digit of our result is 4. 
Result so far: 47964.0654
The remainder is 194 after subtracting 1956 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 13:
When dividing 1940 by 489, we get 3 with a remainder of 473.
Use 3 as the next digit of our solution. 
Result so far: 47964.06543
If we take 1467 away from 1940, we end up with 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

On to step 14:
489 can be fit into 4730 9 times, resulting in a remainder of 329.
Put 9 as the next digit of the answer. 
Result so far: 47964.065439
Subtracting 4401 from 4730 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Step 15:
When dividing 3290 by 489, we get 6 with a remainder of 356.
Record the quotient 6 as the next digit in the result. 
Result so far: 47964.0654396
Deduct 2934 from 3290 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 16:
3560 divided by 489 is 7 with a remainder of 137.
The next digit of our result is 7. 
Result so far: 47964.06543967
The remainder is 137 after subtracting 3423 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

After the division, we end up with 47964.06543967 and a remainder of 1.37e-07.
