Let's divide 21917876 by 456
We want to divide 21917876 by 456.

Let's proceed to step 1:
If we divide 2 by 456, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 456

Advancing to step 2:
456 can be fit into 21 0 times, resulting in a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 456

On to step 3:
When dividing 219 by 456, we get 0 with a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 219 to get 219.
Bring next digit (1) of the dividend behind the 219 and repeat the process: 2191 / 456

Step 4:
When dividing 2191 by 456, we get 4 with a remainder of 367.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 1824 from 2191, we get 367.
Append the next digit (7) from the dividend to 367 and continue with: 3677 / 456

On to step 5:
If we divide 3677 by 456, we get 8 and a remainder of 29.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 3648 from 3677 and we're left with 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 456

Let's proceed to step 6:
The number 456 fits into 298 0 times, leaving a remainder of 298.
Write down 0 as next digit of the result. 
Result so far: 480.0
Subtracting 0 from 298 leaves us with 298.
Grab the next digit (7) from the dividend, add it to 298, then carry on: 2987 / 456

Going ahead to step 7:
456 goes into 2987 6 times with a remainder of 251.
Use 6 as the next digit of our solution. 
Result so far: 4806.0
Subtracting 2736 from 2987 leaves us with 251.
Grab the next digit (6) from the dividend, add it to 251, then carry on: 2516 / 456

Advancing to step 8:
The number 456 fits into 2516 5 times, leaving a remainder of 236.
Record the quotient 5 as the next digit in the result. 
Result so far: 48065.0
Subtracting 2280 from 2516 leaves us with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Step 9:
456 can be fit into 2360 5 times, resulting in a remainder of 80.
Use 5 as the next digit of our solution. 
Result so far: 48065.5
Subtract 2280 from 2360 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
456 goes into 800 1 times with a remainder of 344.
The next digit of our result is 1. 
Result so far: 48065.51
The remainder is 344 after subtracting 456 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

On to step 11:
When dividing 3440 by 456, we get 7 with a remainder of 248.
Use 7 as the next digit of our solution. 
Result so far: 48065.517
The remainder is 248 after subtracting 3192 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 12:
When dividing 2480 by 456, we get 5 with a remainder of 200.
The next digit of our result is 5. 
Result so far: 48065.5175
The remainder is 200 after subtracting 2280 from 2480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 13:
The number 456 fits into 2000 4 times, leaving a remainder of 176.
Write down 4 as next digit of the result. 
Result so far: 48065.51754
Subtract 1824 from 2000 to get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 14:
1760 divided by 456 is 3 with a remainder of 392.
The next digit of our result is 3. 
Result so far: 48065.517543
Deduct 1368 from 1760 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 15:
456 goes into 3920 8 times with a remainder of 272.
The number 8 becomes the next digit in our result. 
Result so far: 48065.5175438
Subtracting 3648 from 3920 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 16:
If we divide 2720 by 456, we get 5 and a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 48065.51754385
Subtract 2280 from 2720 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Our division results in 48065.51754385 with a remaining 4.4e-07.
