30687286 ÷ 724 
We want to figure out the number of times 30687286 can be divided by 724.

Step 1:
724 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 724

Let's proceed to step 2:
The number 724 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 724

Step 3:
724 goes into 306 0 times with a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 306, we get 306.
Take the next digit (8) from the dividend and append it to 306, then repeat: 3068 / 724

Moving on to step 4:
If we divide 3068 by 724, we get 4 and a remainder of 172.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 172 after subtracting 2896 from 3068.
Grab the next digit (7) from the dividend, add it to 172, then carry on: 1727 / 724

Let's proceed to step 5:
1727 divided by 724 is 2 with a remainder of 279.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 1448 from 1727 and we're left with 279.
Bring next digit (2) of the dividend behind the 279 and repeat the process: 2792 / 724

Step 6:
The number 724 fits into 2792 3 times, leaving a remainder of 620.
Write down 3 as next digit of the result. 
Result so far: 423.0
Subtracting 2172 from 2792 leaves us with 620.
Bring next digit (8) of the dividend behind the 620 and repeat the process: 6208 / 724

Step 7:
The number 724 fits into 6208 8 times, leaving a remainder of 416.
The next digit of our result is 8. 
Result so far: 4238.0
If we take 5792 away from 6208, we end up with 416.
Bring next digit (6) of the dividend behind the 416 and repeat the process: 4166 / 724

Advancing to step 8:
If we divide 4166 by 724, we get 5 and a remainder of 546.
Write down 5 as next digit of the result. 
Result so far: 42385.0
If we subtract 3620 from 4166, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Moving on to step 9:
When dividing 5460 by 724, we get 7 with a remainder of 392.
Write down 7 as next digit of the result. 
Result so far: 42385.7
Subtract 5068 from 5460 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 10:
3920 divided by 724 is 5 with a remainder of 300.
The next digit of our result is 5. 
Result so far: 42385.75
If we take 3620 away from 3920, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
724 goes into 3000 4 times with a remainder of 104.
The next digit of our result is 4. 
Result so far: 42385.754
Subtract 2896 from 3000 to get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
724 can be fit into 1040 1 times, resulting in a remainder of 316.
Use 1 as the next digit of our solution. 
Result so far: 42385.7541
Subtracting 724 from 1040 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 13:
724 goes into 3160 4 times with a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 42385.75414
The remainder is 264 after subtracting 2896 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 14:
If we divide 2640 by 724, we get 3 and a remainder of 468.
Put 3 as the next digit of the answer. 
Result so far: 42385.754143
If we take 2172 away from 2640, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Going ahead to step 15:
The number 724 fits into 4680 6 times, leaving a remainder of 336.
Record the quotient 6 as the next digit in the result. 
Result so far: 42385.7541436
If we take 4344 away from 4680, we end up with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 16:
724 can be fit into 3360 4 times, resulting in a remainder of 464.
The next digit of our result is 4. 
Result so far: 42385.75414364
If we subtract 2896 from 3360, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

After the division, we end up with 42385.75414364 and a remainder of 4.64e-07.
