21551913 ÷ 464 
Let's see how many times 464 fits into 21551913.

Moving on to step 1:
464 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
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 464

Let's proceed to step 2:
If we divide 21 by 464, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 464

Moving on to step 3:
The number 464 fits into 215 0 times, leaving a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Take the next digit (5) from the dividend and append it to 215, then repeat: 2155 / 464

Going ahead to step 4:
464 goes into 2155 4 times with a remainder of 299.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1856 from 2155, we get 299.
Grab the next digit (1) from the dividend, add it to 299, then carry on: 2991 / 464

Let's proceed to step 5:
464 goes into 2991 6 times with a remainder of 207.
Use 6 as the next digit of our solution. 
Result so far: 46.0
Deduct 2784 from 2991 and we're left with 207.
Bring next digit (9) of the dividend behind the 207 and repeat the process: 2079 / 464

Advancing to step 6:
If we divide 2079 by 464, we get 4 and a remainder of 223.
The number 4 becomes the next digit in our result. 
Result so far: 464.0
The remainder is 223 after subtracting 1856 from 2079.
Include the next digit (1) from the dividend after 223, then repeat: 2231 / 464

On to step 7:
464 goes into 2231 4 times with a remainder of 375.
Use 4 as the next digit of our solution. 
Result so far: 4644.0
Subtracting 1856 from 2231 leaves us with 375.
Append the next digit (3) from the dividend to 375 and continue with: 3753 / 464

On to step 8:
When dividing 3753 by 464, we get 8 with a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 46448.0
Subtract 3712 from 3753 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
The number 464 fits into 410 0 times, leaving a remainder of 410.
The next digit of our result is 0. 
Result so far: 46448.0
Subtract 0 from 410 to 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.

On to step 10:
If we divide 4100 by 464, we get 8 and a remainder of 388.
Use 8 as the next digit of our solution. 
Result so far: 46448.08
The remainder is 388 after subtracting 3712 from 4100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
464 goes into 3880 8 times with a remainder of 168.
Record the quotient 8 as the next digit in the result. 
Result so far: 46448.088
Deduct 3712 from 3880 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The quotient of the division is 46448.088, and the remainder is 0.0168.
