28158964 ÷ 721 
We're looking to find how many times 721 goes into 28158964.

Moving on to step 1:
The number 721 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 721

Let's proceed to step 2:
721 goes into 28 0 times with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 721

Moving on to step 3:
281 divided by 721 is 0 with a remainder of 281.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 281 after subtracting 0 from 281.
Grab the next digit (5) from the dividend, add it to 281, then carry on: 2815 / 721

On to step 4:
If we divide 2815 by 721, we get 3 and a remainder of 652.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 2163 from 2815 and we're left with 652.
Include the next digit (8) from the dividend after 652, then repeat: 6528 / 721

Step 5:
If we divide 6528 by 721, we get 9 and a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 6489 from 6528 leaves us with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 721

On to step 6:
The number 721 fits into 399 0 times, leaving a remainder of 399.
The next digit of our result is 0. 
Result so far: 390.0
Subtracting 0 from 399 leaves us with 399.
Include the next digit (6) from the dividend after 399, then repeat: 3996 / 721

Step 7:
721 can be fit into 3996 5 times, resulting in a remainder of 391.
The number 5 becomes the next digit in our result. 
Result so far: 3905.0
If we subtract 3605 from 3996, we get 391.
Include the next digit (4) from the dividend after 391, then repeat: 3914 / 721

Step 8:
When dividing 3914 by 721, we get 5 with a remainder of 309.
Use 5 as the next digit of our solution. 
Result so far: 39055.0
Deduct 3605 from 3914 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Let's proceed to step 9:
When dividing 3090 by 721, we get 4 with a remainder of 206.
Use 4 as the next digit of our solution. 
Result so far: 39055.4
If we take 2884 away from 3090, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 10:
2060 divided by 721 is 2 with a remainder of 618.
Put 2 as the next digit of the answer. 
Result so far: 39055.42
Deduct 1442 from 2060 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 11:
The number 721 fits into 6180 8 times, leaving a remainder of 412.
The number 8 becomes the next digit in our result. 
Result so far: 39055.428
Subtract 5768 from 6180 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Advancing to step 12:
If we divide 4120 by 721, we get 5 and a remainder of 515.
Write down 5 as next digit of the result. 
Result so far: 39055.4285
If we subtract 3605 from 4120, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 13:
5150 divided by 721 is 7 with a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 39055.42857
Subtracting 5047 from 5150 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 14:
When dividing 1030 by 721, we get 1 with a remainder of 309.
The number 1 becomes the next digit in our result. 
Result so far: 39055.428571
Subtracting 721 from 1030 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 15:
3090 divided by 721 is 4 with a remainder of 206.
Use 4 as the next digit of our solution. 
Result so far: 39055.4285714
The remainder is 206 after subtracting 2884 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 16:
When dividing 2060 by 721, we get 2 with a remainder of 618.
The next digit of our result is 2. 
Result so far: 39055.42857142
Subtract 1442 from 2060 to get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

The final result is 39055.42857142 with a remainder of 6.18e-07.
