56399830 ÷ 456 
We want to divide 56399830 by 456.

Moving on to step 1:
When dividing 5 by 456, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 456

Let's proceed to step 2:
456 can be fit into 56 0 times, resulting in a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Append the next digit (3) from the dividend to 56 and continue with: 563 / 456

Moving on to step 3:
456 can be fit into 563 1 times, resulting in a remainder of 107.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 456 from 563 leaves us with 107.
Include the next digit (9) from the dividend after 107, then repeat: 1079 / 456

Moving on to step 4:
If we divide 1079 by 456, we get 2 and a remainder of 167.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 912 away from 1079, we end up with 167.
Include the next digit (9) from the dividend after 167, then repeat: 1679 / 456

Moving on to step 5:
456 goes into 1679 3 times with a remainder of 311.
Use 3 as the next digit of our solution. 
Result so far: 123.0
If we take 1368 away from 1679, we end up with 311.
Take the next digit (8) from the dividend and append it to 311, then repeat: 3118 / 456

On to step 6:
456 can be fit into 3118 6 times, resulting in a remainder of 382.
The next digit of our result is 6. 
Result so far: 1236.0
Subtracting 2736 from 3118 leaves us with 382.
Append the next digit (3) from the dividend to 382 and continue with: 3823 / 456

On to step 7:
456 can be fit into 3823 8 times, resulting in a remainder of 175.
Write down 8 as next digit of the result. 
Result so far: 12368.0
If we take 3648 away from 3823, we end up with 175.
Take the next digit (0) from the dividend and append it to 175, then repeat: 1750 / 456

Advancing to step 8:
If we divide 1750 by 456, we get 3 and a remainder of 382.
Put 3 as the next digit of the answer. 
Result so far: 123683.0
The remainder is 382 after subtracting 1368 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

On to step 9:
456 goes into 3820 8 times with a remainder of 172.
The next digit of our result is 8. 
Result so far: 123683.8
Subtracting 3648 from 3820 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 10:
456 can be fit into 1720 3 times, resulting in a remainder of 352.
Write down 3 as next digit of the result. 
Result so far: 123683.83
Subtracting 1368 from 1720 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Advancing to step 11:
456 can be fit into 3520 7 times, resulting in a remainder of 328.
The number 7 becomes the next digit in our result. 
Result so far: 123683.837
Subtracting 3192 from 3520 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

On to step 12:
456 goes into 3280 7 times with a remainder of 88.
The next digit of our result is 7. 
Result so far: 123683.8377
If we subtract 3192 from 3280, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The quotient of the division is 123683.8377, and the remainder is 0.00088.
