Let's divide 77272121 by 439
We're looking to find how many times 439 goes into 77272121.

Going ahead to step 1:
439 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 439

Going ahead to step 2:
When dividing 77 by 439, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 439

Going ahead to step 3:
If we divide 772 by 439, we get 1 and a remainder of 333.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 333 after subtracting 439 from 772.
Grab the next digit (7) from the dividend, add it to 333, then carry on: 3337 / 439

On to step 4:
When dividing 3337 by 439, we get 7 with a remainder of 264.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 264 after subtracting 3073 from 3337.
Bring next digit (2) of the dividend behind the 264 and repeat the process: 2642 / 439

Advancing to step 5:
The number 439 fits into 2642 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 176.0
If we subtract 2634 from 2642, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 439

Advancing to step 6:
If we divide 81 by 439, we get 0 and a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 1760.0
Subtract 0 from 81 to get 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 439

On to step 7:
812 divided by 439 is 1 with a remainder of 373.
Put 1 as the next digit of the answer. 
Result so far: 17601.0
Subtract 439 from 812 to get 373.
Bring next digit (1) of the dividend behind the 373 and repeat the process: 3731 / 439

Going ahead to step 8:
439 can be fit into 3731 8 times, resulting in a remainder of 219.
Write down 8 as next digit of the result. 
Result so far: 176018.0
If we take 3512 away from 3731, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Going ahead to step 9:
2190 divided by 439 is 4 with a remainder of 434.
The number 4 becomes the next digit in our result. 
Result so far: 176018.4
If we subtract 1756 from 2190, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Advancing to step 10:
439 can be fit into 4340 9 times, resulting in a remainder of 389.
Write down 9 as next digit of the result. 
Result so far: 176018.49
If we subtract 3951 from 4340, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

On to step 11:
The number 439 fits into 3890 8 times, leaving a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 176018.498
The remainder is 378 after subtracting 3512 from 3890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 12:
If we divide 3780 by 439, we get 8 and a remainder of 268.
The next digit of our result is 8. 
Result so far: 176018.4988
Subtract 3512 from 3780 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

In conclusion, the division gives 176018.4988 with a balance of 0.00268.
