51008481 ÷ 115 
We're looking to find how many times 115 goes into 51008481.

Moving on to step 1:
When dividing 5 by 115, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 115

Going ahead to step 2:
If we divide 51 by 115, we get 0 and a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 115

Step 3:
115 goes into 510 4 times with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 460 from 510 to get 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 115

On to step 4:
If we divide 500 by 115, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 40 after subtracting 460 from 500.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 115

Going ahead to step 5:
115 goes into 408 3 times with a remainder of 63.
Write down 3 as next digit of the result. 
Result so far: 443.0
Deduct 345 from 408 and we're left with 63.
Take the next digit (4) from the dividend and append it to 63, then repeat: 634 / 115

Advancing to step 6:
115 goes into 634 5 times with a remainder of 59.
Record the quotient 5 as the next digit in the result. 
Result so far: 4435.0
Subtract 575 from 634 to get 59.
Grab the next digit (8) from the dividend, add it to 59, then carry on: 598 / 115

Moving on to step 7:
598 divided by 115 is 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 44355.0
Deduct 575 from 598 and we're left with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 115

Going ahead to step 8:
115 can be fit into 231 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 443552.0
If we subtract 230 from 231, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
If we divide 10 by 115, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 443552.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
115 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 443552.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Our division results in 443552.0 with a remaining 0.1.
