We're dividing 28976080 by 721 
We want to figure out the number of times 28976080 can be divided by 721.

Going ahead to step 1:
The number 721 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 721

Moving on to step 2:
The number 721 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Bring next digit (9) of the dividend behind the 28 and repeat the process: 289 / 721

Going ahead to step 3:
The number 721 fits into 289 0 times, leaving a remainder of 289.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 289, we get 289.
Grab the next digit (7) from the dividend, add it to 289, then carry on: 2897 / 721

Let's proceed to step 4:
The number 721 fits into 2897 4 times, leaving a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2884 from 2897, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 721

Step 5:
721 can be fit into 136 0 times, resulting in a remainder of 136.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 136 after subtracting 0 from 136.
Append the next digit (0) from the dividend to 136 and continue with: 1360 / 721

Going ahead to step 6:
1360 divided by 721 is 1 with a remainder of 639.
The next digit of our result is 1. 
Result so far: 401.0
Subtract 721 from 1360 to get 639.
Grab the next digit (8) from the dividend, add it to 639, then carry on: 6398 / 721

Step 7:
721 goes into 6398 8 times with a remainder of 630.
The next digit of our result is 8. 
Result so far: 4018.0
If we take 5768 away from 6398, we end up with 630.
Fetch the next digit (0) from the dividend, attach it to 630 and continue: 6300 / 721

Advancing to step 8:
6300 divided by 721 is 8 with a remainder of 532.
The number 8 becomes the next digit in our result. 
Result so far: 40188.0
Deduct 5768 from 6300 and we're left with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

On to step 9:
5320 divided by 721 is 7 with a remainder of 273.
The number 7 becomes the next digit in our result. 
Result so far: 40188.7
If we subtract 5047 from 5320, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 10:
721 goes into 2730 3 times with a remainder of 567.
Record the quotient 3 as the next digit in the result. 
Result so far: 40188.73
If we subtract 2163 from 2730, we get 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Going ahead to step 11:
5670 divided by 721 is 7 with a remainder of 623.
Put 7 as the next digit of the answer. 
Result so far: 40188.737
If we take 5047 away from 5670, we end up with 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Advancing to step 12:
721 goes into 6230 8 times with a remainder of 462.
The next digit of our result is 8. 
Result so far: 40188.7378
Deduct 5768 from 6230 and we're left with 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4620, and continue the process.

Advancing to step 13:
When dividing 4620 by 721, we get 6 with a remainder of 294.
Use 6 as the next digit of our solution. 
Result so far: 40188.73786
Subtracting 4326 from 4620 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 14:
If we divide 2940 by 721, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 40188.737864
The remainder is 56 after subtracting 2884 from 2940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 15:
If we divide 560 by 721, we get 0 and a remainder of 560.
Put 0 as the next digit of the answer. 
Result so far: 40188.737864
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 16:
5600 divided by 721 is 7 with a remainder of 553.
The number 7 becomes the next digit in our result. 
Result so far: 40188.73786407
If we take 5047 away from 5600, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Our division results in 40188.73786407 with a remaining 5.53e-07.
