56510128 divided by 343 
We want to divide 56510128 by 343.

Let's proceed to step 1:
When dividing 5 by 343, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 343

Let's proceed to step 2:
56 divided by 343 is 0 with a remainder of 56.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 343

Step 3:
The number 343 fits into 565 1 times, leaving a remainder of 222.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 343 from 565 to get 222.
Grab the next digit (1) from the dividend, add it to 222, then carry on: 2221 / 343

Step 4:
2221 divided by 343 is 6 with a remainder of 163.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2058 from 2221 to get 163.
Append the next digit (0) from the dividend to 163 and continue with: 1630 / 343

Advancing to step 5:
The number 343 fits into 1630 4 times, leaving a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 164.0
The remainder is 258 after subtracting 1372 from 1630.
Bring next digit (1) of the dividend behind the 258 and repeat the process: 2581 / 343

On to step 6:
When dividing 2581 by 343, we get 7 with a remainder of 180.
Put 7 as the next digit of the answer. 
Result so far: 1647.0
Subtract 2401 from 2581 to get 180.
Take the next digit (2) from the dividend and append it to 180, then repeat: 1802 / 343

Going ahead to step 7:
343 goes into 1802 5 times with a remainder of 87.
Write down 5 as next digit of the result. 
Result so far: 16475.0
The remainder is 87 after subtracting 1715 from 1802.
Include the next digit (8) from the dividend after 87, then repeat: 878 / 343

Moving on to step 8:
343 can be fit into 878 2 times, resulting in a remainder of 192.
The next digit of our result is 2. 
Result so far: 164752.0
Subtracting 686 from 878 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 9:
The number 343 fits into 1920 5 times, leaving a remainder of 205.
Write down 5 as next digit of the result. 
Result so far: 164752.5
If we take 1715 away from 1920, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Going ahead to step 10:
The number 343 fits into 2050 5 times, leaving a remainder of 335.
The next digit of our result is 5. 
Result so far: 164752.55
If we subtract 1715 from 2050, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The quotient of the division is 164752.55, and the remainder is 0.335.
