We divide 50518186 by 129
We want to divide 50518186 by 129.

Moving on to step 1:
129 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 129

Let's proceed to step 2:
50 divided by 129 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 129

On to step 3:
When dividing 505 by 129, we get 3 with a remainder of 118.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 387 from 505, we get 118.
Append the next digit (1) from the dividend to 118 and continue with: 1181 / 129

On to step 4:
The number 129 fits into 1181 9 times, leaving a remainder of 20.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 1161 from 1181, we get 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 129

Going ahead to step 5:
If we divide 208 by 129, we get 1 and a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 391.0
The remainder is 79 after subtracting 129 from 208.
Bring next digit (1) of the dividend behind the 79 and repeat the process: 791 / 129

Let's proceed to step 6:
791 divided by 129 is 6 with a remainder of 17.
Record the quotient 6 as the next digit in the result. 
Result so far: 3916.0
If we take 774 away from 791, we end up with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 129

Advancing to step 7:
When dividing 178 by 129, we get 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 39161.0
Deduct 129 from 178 and we're left with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 129

Moving on to step 8:
129 goes into 496 3 times with a remainder of 109.
Use 3 as the next digit of our solution. 
Result so far: 391613.0
Deduct 387 from 496 and we're left with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Going ahead to step 9:
1090 divided by 129 is 8 with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 391613.8
Deduct 1032 from 1090 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 10:
580 divided by 129 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 391613.84
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 11:
129 can be fit into 640 4 times, resulting in a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 391613.844
Deduct 516 from 640 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Our division results in 391613.844 with a remaining 0.0124.
