21798999 ÷ 521 
We want to divide 21798999 by 521.

Going ahead to step 1:
2 divided by 521 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 521

Step 2:
521 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 521

Moving on to step 3:
If we divide 217 by 521, we get 0 and a remainder of 217.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 217, we end up with 217.
Bring next digit (9) of the dividend behind the 217 and repeat the process: 2179 / 521

Moving on to step 4:
When dividing 2179 by 521, we get 4 with a remainder of 95.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 95 after subtracting 2084 from 2179.
Bring next digit (8) of the dividend behind the 95 and repeat the process: 958 / 521

Let's proceed to step 5:
521 can be fit into 958 1 times, resulting in a remainder of 437.
Write down 1 as next digit of the result. 
Result so far: 41.0
The remainder is 437 after subtracting 521 from 958.
Grab the next digit (9) from the dividend, add it to 437, then carry on: 4379 / 521

On to step 6:
521 can be fit into 4379 8 times, resulting in a remainder of 211.
Put 8 as the next digit of the answer. 
Result so far: 418.0
Subtracting 4168 from 4379 leaves us with 211.
Bring next digit (9) of the dividend behind the 211 and repeat the process: 2119 / 521

On to step 7:
The number 521 fits into 2119 4 times, leaving a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 4184.0
The remainder is 35 after subtracting 2084 from 2119.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 521

Step 8:
If we divide 359 by 521, we get 0 and a remainder of 359.
Write down 0 as next digit of the result. 
Result so far: 41840.0
Subtract 0 from 359 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 9:
3590 divided by 521 is 6 with a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 41840.6
If we subtract 3126 from 3590, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 10:
521 goes into 4640 8 times with a remainder of 472.
Use 8 as the next digit of our solution. 
Result so far: 41840.68
Deduct 4168 from 4640 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 11:
The number 521 fits into 4720 9 times, leaving a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 41840.689
Subtract 4689 from 4720 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 12:
521 goes into 310 0 times with a remainder of 310.
Write down 0 as next digit of the result. 
Result so far: 41840.689
Subtract 0 from 310 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 13:
3100 divided by 521 is 5 with a remainder of 495.
The next digit of our result is 5. 
Result so far: 41840.68905
Subtracting 2605 from 3100 leaves us with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

On to step 14:
The number 521 fits into 4950 9 times, leaving a remainder of 261.
The number 9 becomes the next digit in our result. 
Result so far: 41840.689059
Subtract 4689 from 4950 to get 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Moving on to step 15:
521 goes into 2610 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 41840.6890595
Subtracting 2605 from 2610 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 16:
521 goes into 50 0 times with a remainder of 50.
The next digit of our result is 0. 
Result so far: 41840.6890595
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 41840.6890595 with a remaining 5e-08.
