72154945 divided by 489 
We want to divide 72154945 by 489.

Step 1:
If we divide 7 by 489, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 489

Step 2:
If we divide 72 by 489, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 489

On to step 3:
The number 489 fits into 721 1 times, leaving a remainder of 232.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 489 from 721 leaves us with 232.
Fetch the next digit (5) from the dividend, attach it to 232 and continue: 2325 / 489

Moving on to step 4:
489 can be fit into 2325 4 times, resulting in a remainder of 369.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 1956 from 2325 to get 369.
Bring next digit (4) of the dividend behind the 369 and repeat the process: 3694 / 489

Going ahead to step 5:
3694 divided by 489 is 7 with a remainder of 271.
Put 7 as the next digit of the answer. 
Result so far: 147.0
Subtracting 3423 from 3694 leaves us with 271.
Fetch the next digit (9) from the dividend, attach it to 271 and continue: 2719 / 489

Moving on to step 6:
489 goes into 2719 5 times with a remainder of 274.
The next digit of our result is 5. 
Result so far: 1475.0
If we take 2445 away from 2719, we end up with 274.
Grab the next digit (4) from the dividend, add it to 274, then carry on: 2744 / 489

Moving on to step 7:
If we divide 2744 by 489, we get 5 and a remainder of 299.
The next digit of our result is 5. 
Result so far: 14755.0
Subtract 2445 from 2744 to get 299.
Include the next digit (5) from the dividend after 299, then repeat: 2995 / 489

Let's proceed to step 8:
489 can be fit into 2995 6 times, resulting in a remainder of 61.
The number 6 becomes the next digit in our result. 
Result so far: 147556.0
If we take 2934 away from 2995, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 9:
610 divided by 489 is 1 with a remainder of 121.
The next digit of our result is 1. 
Result so far: 147556.1
Subtracting 489 from 610 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Advancing to step 10:
When dividing 1210 by 489, we get 2 with a remainder of 232.
The number 2 becomes the next digit in our result. 
Result so far: 147556.12
Subtracting 978 from 1210 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 11:
When dividing 2320 by 489, we get 4 with a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 147556.124
Subtract 1956 from 2320 to get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Let's proceed to step 12:
The number 489 fits into 3640 7 times, leaving a remainder of 217.
Put 7 as the next digit of the answer. 
Result so far: 147556.1247
If we subtract 3423 from 3640, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 13:
If we divide 2170 by 489, we get 4 and a remainder of 214.
Put 4 as the next digit of the answer. 
Result so far: 147556.12474
Subtract 1956 from 2170 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Step 14:
2140 divided by 489 is 4 with a remainder of 184.
Record the quotient 4 as the next digit in the result. 
Result so far: 147556.124744
Deduct 1956 from 2140 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The quotient of the division is 147556.124744, and the remainder is 1.84e-05.
