51186311 divided by 434 
We want to figure out the number of times 51186311 can be divided by 434.

Moving on to step 1:
434 goes into 5 0 times 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.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 434

On to step 2:
51 divided by 434 is 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 434

Let's proceed to step 3:
434 goes into 511 1 times with a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 434 from 511 and we're left with 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 434

Moving on to step 4:
434 can be fit into 778 1 times, resulting in a remainder of 344.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 434 from 778 leaves us with 344.
Append the next digit (6) from the dividend to 344 and continue with: 3446 / 434

Step 5:
If we divide 3446 by 434, we get 7 and a remainder of 408.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
If we subtract 3038 from 3446, we get 408.
Append the next digit (3) from the dividend to 408 and continue with: 4083 / 434

Moving on to step 6:
When dividing 4083 by 434, we get 9 with a remainder of 177.
Record the quotient 9 as the next digit in the result. 
Result so far: 1179.0
If we take 3906 away from 4083, we end up with 177.
Fetch the next digit (1) from the dividend, attach it to 177 and continue: 1771 / 434

On to step 7:
434 can be fit into 1771 4 times, resulting in a remainder of 35.
Use 4 as the next digit of our solution. 
Result so far: 11794.0
Subtract 1736 from 1771 to get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 434

Moving on to step 8:
If we divide 351 by 434, we get 0 and a remainder of 351.
The next digit of our result is 0. 
Result so far: 117940.0
If we take 0 away from 351, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Moving on to step 9:
The number 434 fits into 3510 8 times, leaving a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 117940.8
The remainder is 38 after subtracting 3472 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
380 divided by 434 is 0 with a remainder of 380.
The number 0 becomes the next digit in our result. 
Result so far: 117940.8
If we subtract 0 from 380, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

On to step 11:
434 goes into 3800 8 times with a remainder of 328.
The number 8 becomes the next digit in our result. 
Result so far: 117940.808
Subtract 3472 from 3800 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 12:
3280 divided by 434 is 7 with a remainder of 242.
The number 7 becomes the next digit in our result. 
Result so far: 117940.8087
Subtracting 3038 from 3280 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 13:
434 goes into 2420 5 times with a remainder of 250.
Record the quotient 5 as the next digit in the result. 
Result so far: 117940.80875
Subtract 2170 from 2420 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 14:
2500 divided by 434 is 5 with a remainder of 330.
The next digit of our result is 5. 
Result so far: 117940.808755
If we take 2170 away from 2500, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Our division results in 117940.808755 with a remaining 3.3e-05.
