Let's divide 77199649 by 489
We want to divide 77199649 by 489.

Advancing to 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
The remainder is 7 after subtracting 0 from 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 489

Advancing to step 2:
When dividing 77 by 489, we get 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 489

Going ahead to step 3:
489 goes into 771 1 times with a remainder of 282.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 489 from 771 leaves us with 282.
Fetch the next digit (9) from the dividend, attach it to 282 and continue: 2829 / 489

On to step 4:
2829 divided by 489 is 5 with a remainder of 384.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 2445 from 2829 and we're left with 384.
Bring next digit (9) of the dividend behind the 384 and repeat the process: 3849 / 489

Moving on to step 5:
If we divide 3849 by 489, we get 7 and a remainder of 426.
Put 7 as the next digit of the answer. 
Result so far: 157.0
If we take 3423 away from 3849, we end up with 426.
Append the next digit (6) from the dividend to 426 and continue with: 4266 / 489

Step 6:
The number 489 fits into 4266 8 times, leaving a remainder of 354.
The number 8 becomes the next digit in our result. 
Result so far: 1578.0
Deduct 3912 from 4266 and we're left with 354.
Bring next digit (4) of the dividend behind the 354 and repeat the process: 3544 / 489

Going ahead to step 7:
3544 divided by 489 is 7 with a remainder of 121.
Write down 7 as next digit of the result. 
Result so far: 15787.0
Subtracting 3423 from 3544 leaves us with 121.
Grab the next digit (9) from the dividend, add it to 121, then carry on: 1219 / 489

Let's proceed to step 8:
If we divide 1219 by 489, we get 2 and a remainder of 241.
The next digit of our result is 2. 
Result so far: 157872.0
If we take 978 away from 1219, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 9:
2410 divided by 489 is 4 with a remainder of 454.
The next digit of our result is 4. 
Result so far: 157872.4
Subtracting 1956 from 2410 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Advancing to step 10:
The number 489 fits into 4540 9 times, leaving a remainder of 139.
The number 9 becomes the next digit in our result. 
Result so far: 157872.49
Subtracting 4401 from 4540 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

On to step 11:
The number 489 fits into 1390 2 times, leaving a remainder of 412.
Put 2 as the next digit of the answer. 
Result so far: 157872.492
Deduct 978 from 1390 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 12:
4120 divided by 489 is 8 with a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 157872.4928
Subtract 3912 from 4120 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 13:
489 can be fit into 2080 4 times, resulting in a remainder of 124.
The number 4 becomes the next digit in our result. 
Result so far: 157872.49284
Subtracting 1956 from 2080 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 14:
When dividing 1240 by 489, we get 2 with a remainder of 262.
Write down 2 as next digit of the result. 
Result so far: 157872.492842
Subtract 978 from 1240 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 15:
The number 489 fits into 2620 5 times, leaving a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 157872.4928425
Subtracting 2445 from 2620 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Step 16:
The number 489 fits into 1750 3 times, leaving a remainder of 283.
Write down 3 as next digit of the result. 
Result so far: 157872.49284253
If we subtract 1467 from 1750, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Our division results in 157872.49284253 with a remaining 2.83e-07.
