42130180 ÷ 856 
Let's see how many times 856 fits into 42130180.

On to step 1:
When dividing 4 by 856, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 856

Moving on to step 2:
If we divide 42 by 856, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 856

Advancing to step 3:
When dividing 421 by 856, we get 0 with a remainder of 421.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 421, we get 421.
Include the next digit (3) from the dividend after 421, then repeat: 4213 / 856

Going ahead to step 4:
If we divide 4213 by 856, we get 4 and a remainder of 789.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 3424 from 4213 to get 789.
Fetch the next digit (0) from the dividend, attach it to 789 and continue: 7890 / 856

Advancing to step 5:
If we divide 7890 by 856, we get 9 and a remainder of 186.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
The remainder is 186 after subtracting 7704 from 7890.
Append the next digit (1) from the dividend to 186 and continue with: 1861 / 856

Moving on to step 6:
When dividing 1861 by 856, we get 2 with a remainder of 149.
Use 2 as the next digit of our solution. 
Result so far: 492.0
Subtract 1712 from 1861 to get 149.
Fetch the next digit (8) from the dividend, attach it to 149 and continue: 1498 / 856

Moving on to step 7:
1498 divided by 856 is 1 with a remainder of 642.
Write down 1 as next digit of the result. 
Result so far: 4921.0
Subtracting 856 from 1498 leaves us with 642.
Append the next digit (0) from the dividend to 642 and continue with: 6420 / 856

Moving on to step 8:
6420 divided by 856 is 7 with a remainder of 428.
Use 7 as the next digit of our solution. 
Result so far: 49217.0
Subtracting 5992 from 6420 leaves us with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 9:
856 goes into 4280 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 49217.5
If we take 4280 away from 4280, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 856 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 49217.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 11:
0 divided by 856 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49217.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 49217.5 with a remainder of 0.0.
