21280046 divided by 726 
We want to figure out the number of times 21280046 can be divided by 726.

Advancing to step 1:
726 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 726

Moving on to step 2:
726 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 726

Step 3:
726 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 212 and we're left with 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 726

On to step 4:
2128 divided by 726 is 2 with a remainder of 676.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 676 after subtracting 1452 from 2128.
Take the next digit (0) from the dividend and append it to 676, then repeat: 6760 / 726

Let's proceed to step 5:
If we divide 6760 by 726, we get 9 and a remainder of 226.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we take 6534 away from 6760, we end up with 226.
Grab the next digit (0) from the dividend, add it to 226, then carry on: 2260 / 726

Moving on to step 6:
If we divide 2260 by 726, we get 3 and a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 293.0
Subtract 2178 from 2260 to get 82.
Fetch the next digit (4) from the dividend, attach it to 82 and continue: 824 / 726

Step 7:
The number 726 fits into 824 1 times, leaving a remainder of 98.
Use 1 as the next digit of our solution. 
Result so far: 2931.0
The remainder is 98 after subtracting 726 from 824.
Bring next digit (6) of the dividend behind the 98 and repeat the process: 986 / 726

Going ahead to step 8:
When dividing 986 by 726, we get 1 with a remainder of 260.
Record the quotient 1 as the next digit in the result. 
Result so far: 29311.0
Subtract 726 from 986 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 9:
726 goes into 2600 3 times with a remainder of 422.
Put 3 as the next digit of the answer. 
Result so far: 29311.3
Subtract 2178 from 2600 to get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Advancing to step 10:
4220 divided by 726 is 5 with a remainder of 590.
Record the quotient 5 as the next digit in the result. 
Result so far: 29311.35
Subtracting 3630 from 4220 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Step 11:
726 can be fit into 5900 8 times, resulting in a remainder of 92.
Record the quotient 8 as the next digit in the result. 
Result so far: 29311.358
If we take 5808 away from 5900, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 12:
If we divide 920 by 726, we get 1 and a remainder of 194.
Put 1 as the next digit of the answer. 
Result so far: 29311.3581
Subtract 726 from 920 to get 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Advancing to step 13:
726 can be fit into 1940 2 times, resulting in a remainder of 488.
Use 2 as the next digit of our solution. 
Result so far: 29311.35812
If we subtract 1452 from 1940, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Step 14:
When dividing 4880 by 726, we get 6 with a remainder of 524.
Write down 6 as next digit of the result. 
Result so far: 29311.358126
Subtract 4356 from 4880 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 15:
When dividing 5240 by 726, we get 7 with a remainder of 158.
The number 7 becomes the next digit in our result. 
Result so far: 29311.3581267
Subtracting 5082 from 5240 leaves us with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 16:
If we divide 1580 by 726, we get 2 and a remainder of 128.
Put 2 as the next digit of the answer. 
Result so far: 29311.35812672
Subtracting 1452 from 1580 leaves us with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final outcome is 29311.35812672, with a leftover of 1.28e-07.
