49129112 ÷ 830 
Let's see how many times 830 fits into 49129112.

Step 1:
830 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 830

Going ahead to step 2:
The number 830 fits into 49 0 times, leaving a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (1) from the dividend, attach it to 49 and continue: 491 / 830

Advancing to step 3:
When dividing 491 by 830, we get 0 with a remainder of 491.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 491, we end up with 491.
Grab the next digit (2) from the dividend, add it to 491, then carry on: 4912 / 830

Moving on to step 4:
When dividing 4912 by 830, we get 5 with a remainder of 762.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 4150 from 4912 to get 762.
Include the next digit (9) from the dividend after 762, then repeat: 7629 / 830

Moving on to step 5:
The number 830 fits into 7629 9 times, leaving a remainder of 159.
Put 9 as the next digit of the answer. 
Result so far: 59.0
Subtracting 7470 from 7629 leaves us with 159.
Take the next digit (1) from the dividend and append it to 159, then repeat: 1591 / 830

Moving on to step 6:
830 can be fit into 1591 1 times, resulting in a remainder of 761.
Write down 1 as next digit of the result. 
Result so far: 591.0
The remainder is 761 after subtracting 830 from 1591.
Bring next digit (1) of the dividend behind the 761 and repeat the process: 7611 / 830

Advancing to step 7:
830 goes into 7611 9 times with a remainder of 141.
The number 9 becomes the next digit in our result. 
Result so far: 5919.0
If we take 7470 away from 7611, we end up with 141.
Append the next digit (2) from the dividend to 141 and continue with: 1412 / 830

Let's proceed to step 8:
830 goes into 1412 1 times with a remainder of 582.
Put 1 as the next digit of the answer. 
Result so far: 59191.0
If we subtract 830 from 1412, we get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Going ahead to step 9:
830 can be fit into 5820 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 59191.7
Deduct 5810 from 5820 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
830 can be fit into 100 0 times, resulting in a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 59191.7
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
When dividing 1000 by 830, we get 1 with a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 59191.701
Deduct 830 from 1000 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 12:
830 goes into 1700 2 times with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 59191.7012
Deduct 1660 from 1700 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
The number 830 fits into 400 0 times, leaving a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 59191.7012
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 14:
The number 830 fits into 4000 4 times, leaving a remainder of 680.
The next digit of our result is 4. 
Result so far: 59191.701204
Deduct 3320 from 4000 and we're left with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 15:
6800 divided by 830 is 8 with a remainder of 160.
Put 8 as the next digit of the answer. 
Result so far: 59191.7012048
Deduct 6640 from 6800 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 16:
When dividing 1600 by 830, we get 1 with a remainder of 770.
The number 1 becomes the next digit in our result. 
Result so far: 59191.70120481
Subtract 830 from 1600 to get 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

After the division, we end up with 59191.70120481 and a remainder of 7.7e-07.
