We divide 21286912 by 464
We're looking to find how many times 464 goes into 21286912.

Step 1:
If we divide 2 by 464, we get 0 and 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.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 464

Let's proceed to step 2:
The number 464 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
If we take 0 away from 21, we end up with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 464

Let's proceed to step 3:
When dividing 212 by 464, we get 0 with a remainder of 212.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 212 leaves us with 212.
Append the next digit (8) from the dividend to 212 and continue with: 2128 / 464

Let's proceed to step 4:
The number 464 fits into 2128 4 times, leaving a remainder of 272.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 272 after subtracting 1856 from 2128.
Append the next digit (6) from the dividend to 272 and continue with: 2726 / 464

Going ahead to step 5:
When dividing 2726 by 464, we get 5 with a remainder of 406.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 2320 from 2726, we get 406.
Append the next digit (9) from the dividend to 406 and continue with: 4069 / 464

Let's proceed to step 6:
464 can be fit into 4069 8 times, resulting in a remainder of 357.
Record the quotient 8 as the next digit in the result. 
Result so far: 458.0
If we subtract 3712 from 4069, we get 357.
Include the next digit (1) from the dividend after 357, then repeat: 3571 / 464

Let's proceed to step 7:
3571 divided by 464 is 7 with a remainder of 323.
Use 7 as the next digit of our solution. 
Result so far: 4587.0
Deduct 3248 from 3571 and we're left with 323.
Fetch the next digit (2) from the dividend, attach it to 323 and continue: 3232 / 464

Going ahead to step 8:
3232 divided by 464 is 6 with a remainder of 448.
Put 6 as the next digit of the answer. 
Result so far: 45876.0
Subtract 2784 from 3232 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 9:
464 can be fit into 4480 9 times, resulting in a remainder of 304.
Put 9 as the next digit of the answer. 
Result so far: 45876.9
The remainder is 304 after subtracting 4176 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 10:
464 goes into 3040 6 times with a remainder of 256.
Use 6 as the next digit of our solution. 
Result so far: 45876.96
Subtract 2784 from 3040 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 11:
When dividing 2560 by 464, we get 5 with a remainder of 240.
Write down 5 as next digit of the result. 
Result so far: 45876.965
Subtracting 2320 from 2560 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 12:
464 can be fit into 2400 5 times, resulting in a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 45876.9655
If we take 2320 away from 2400, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 45876.9655, with a leftover of 0.0008.
