Let's divide 21951258 by 730
We want to divide 21951258 by 730.

Advancing to step 1:
The number 730 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 730

Going ahead to step 2:
When dividing 21 by 730, we get 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 730

Going ahead to step 3:
730 goes into 219 0 times with a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 219 to get 219.
Grab the next digit (5) from the dividend, add it to 219, then carry on: 2195 / 730

Step 4:
730 goes into 2195 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 2190 away from 2195, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 730

Let's proceed to step 5:
If we divide 51 by 730, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 730

Going ahead to step 6:
512 divided by 730 is 0 with a remainder of 512.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
If we take 0 away from 512, we end up with 512.
Fetch the next digit (5) from the dividend, attach it to 512 and continue: 5125 / 730

Going ahead to step 7:
The number 730 fits into 5125 7 times, leaving a remainder of 15.
The next digit of our result is 7. 
Result so far: 3007.0
Deduct 5110 from 5125 and we're left with 15.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 730

Going ahead to step 8:
730 can be fit into 158 0 times, resulting in a remainder of 158.
The next digit of our result is 0. 
Result so far: 30070.0
If we subtract 0 from 158, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
The number 730 fits into 1580 2 times, leaving a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 30070.2
The remainder is 120 after subtracting 1460 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
When dividing 1200 by 730, we get 1 with a remainder of 470.
Use 1 as the next digit of our solution. 
Result so far: 30070.21
If we take 730 away from 1200, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 11:
When dividing 4700 by 730, we get 6 with a remainder of 320.
The next digit of our result is 6. 
Result so far: 30070.216
Deduct 4380 from 4700 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Let's proceed to step 12:
If we divide 3200 by 730, we get 4 and a remainder of 280.
Put 4 as the next digit of the answer. 
Result so far: 30070.2164
Deduct 2920 from 3200 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 13:
If we divide 2800 by 730, we get 3 and a remainder of 610.
Write down 3 as next digit of the result. 
Result so far: 30070.21643
If we subtract 2190 from 2800, we get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Let's proceed to step 14:
The number 730 fits into 6100 8 times, leaving a remainder of 260.
The next digit of our result is 8. 
Result so far: 30070.216438
Deduct 5840 from 6100 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 15:
If we divide 2600 by 730, we get 3 and a remainder of 410.
Use 3 as the next digit of our solution. 
Result so far: 30070.2164383
If we subtract 2190 from 2600, we get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 16:
The number 730 fits into 4100 5 times, leaving a remainder of 450.
Write down 5 as next digit of the result. 
Result so far: 30070.21643835
The remainder is 450 after subtracting 3650 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 30070.21643835 and a remainder of 4.5e-07.
