21306318 ÷ 611 
We want to figure out the number of times 21306318 can be divided by 611.

Let's proceed to step 1:
611 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 611

Advancing to step 2:
If we divide 21 by 611, we get 0 and a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 611

Step 3:
The number 611 fits into 213 0 times, leaving a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Grab the next digit (0) from the dividend, add it to 213, then carry on: 2130 / 611

On to step 4:
2130 divided by 611 is 3 with a remainder of 297.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 1833 from 2130 and we're left with 297.
Take the next digit (6) from the dividend and append it to 297, then repeat: 2976 / 611

Let's proceed to step 5:
The number 611 fits into 2976 4 times, leaving a remainder of 532.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 2444 from 2976 and we're left with 532.
Append the next digit (3) from the dividend to 532 and continue with: 5323 / 611

On to step 6:
When dividing 5323 by 611, we get 8 with a remainder of 435.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
The remainder is 435 after subtracting 4888 from 5323.
Fetch the next digit (1) from the dividend, attach it to 435 and continue: 4351 / 611

Let's proceed to step 7:
4351 divided by 611 is 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 3487.0
Deduct 4277 from 4351 and we're left with 74.
Grab the next digit (8) from the dividend, add it to 74, then carry on: 748 / 611

Step 8:
611 goes into 748 1 times with a remainder of 137.
Write down 1 as next digit of the result. 
Result so far: 34871.0
If we take 611 away from 748, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 9:
1370 divided by 611 is 2 with a remainder of 148.
The next digit of our result is 2. 
Result so far: 34871.2
If we take 1222 away from 1370, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
If we divide 1480 by 611, we get 2 and a remainder of 258.
The next digit of our result is 2. 
Result so far: 34871.22
Deduct 1222 from 1480 and we're left with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Our division results in 34871.22 with a remaining 0.258.
