We divide 21558337 by 518
We're looking to find how many times 518 goes into 21558337.

Going ahead to step 1:
518 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 518

Advancing to step 2:
The number 518 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 518

On to step 3:
If we divide 215 by 518, we get 0 and a remainder of 215.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 215 leaves us with 215.
Fetch the next digit (5) from the dividend, attach it to 215 and continue: 2155 / 518

Going ahead to step 4:
518 goes into 2155 4 times with a remainder of 83.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 2072 from 2155 and we're left with 83.
Fetch the next digit (8) from the dividend, attach it to 83 and continue: 838 / 518

On to step 5:
When dividing 838 by 518, we get 1 with a remainder of 320.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 518 from 838 to get 320.
Append the next digit (3) from the dividend to 320 and continue with: 3203 / 518

Advancing to step 6:
3203 divided by 518 is 6 with a remainder of 95.
The number 6 becomes the next digit in our result. 
Result so far: 416.0
Deduct 3108 from 3203 and we're left with 95.
Fetch the next digit (3) from the dividend, attach it to 95 and continue: 953 / 518

On to step 7:
If we divide 953 by 518, we get 1 and a remainder of 435.
The number 1 becomes the next digit in our result. 
Result so far: 4161.0
The remainder is 435 after subtracting 518 from 953.
Bring next digit (7) of the dividend behind the 435 and repeat the process: 4357 / 518

Moving on to step 8:
If we divide 4357 by 518, we get 8 and a remainder of 213.
Put 8 as the next digit of the answer. 
Result so far: 41618.0
If we subtract 4144 from 4357, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 9:
2130 divided by 518 is 4 with a remainder of 58.
Record the quotient 4 as the next digit in the result. 
Result so far: 41618.4
If we subtract 2072 from 2130, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
518 goes into 580 1 times with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 41618.41
Subtracting 518 from 580 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
518 goes into 620 1 times with a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 41618.411
Subtracting 518 from 620 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 41618.411 with a remaining 0.0102.
